New Feature Summary for Cisco IOS Release 15.2(4)EA lists new features added in added in Cisco IOS Release 15.2(4)EA.
MRP (Media Redundancy Protocol), an open standard industrial protocol for the IE2000, can support up to 50 nodes with maximum recovery time up to 200ms. MRP operates at the MAC layer and is commonly used in conjunction with the PROFINET standard for industrial networking in manufacturing. ■PROFINET stack upgrade to version 2.31. ■PROFINET support for MRP Manager (MRM) and Client (MRC) functionality. PROFINET (PNIO) Certification with v2.3 |

||
This feature enhances Express Startup to limit manual switch intervention. There are three options for using Express Setup:
■You must configure a new in the box (NIB) switch that has no configuration file loaded (config.text / vlan.dat) directly via a console cable. ■You can configure the switch with the existing Express Setup method. The existing Express Setup behavior is enhanced to improve the failure LED indication behavior. ■You can have an IP address assigned to the switch without using Device Manager if you installed the switch in an already running environment with certain services available (DHCP). A new command, locate-switch, causes the EXP/Setup indicator LED to blink green, providing a visual indication of the switch's location. This feature also includes the ability to set up the switch through Add-On Profile (AOP) by enhancing CIP. |

This time service enhancement allows the IE switches to act as Grandmaster clocks to the PTP hierarchy with NTP as the time source. The NTP time source ties the PTP working clock to the everyday “wall clock.” This allows the customer to use PTP and NTP generated timestamps together during troubleshooting and analysis. In addition, NTP is more cost effective and robust than GPS for applications that only need ~1 second precision for wide-area synchronization. |
■ Precision Time Protocol Software Configuration Guide for IE 4000 Switches |
||
This feature adds options for Boundary Clock (BC) synchronization to accommodate various PTP use cases. For improved convergence time in PTP networks, you can configure Boundary Clocks to use a feedforward algorithm to measure the delay added by the network elements forwarding plane (the disturbance) and use that measured delay to control the time output. You can configure the switch for linear packet delay variation (PDV) filtering or adaptive filtering, which filters as much PDV as possible. Note that adaptive filtering is not supported in Power Profile mode. |

MODBUS is an application layer messaging protocol that provides client/server communication between devices connected on different types of buses or networks.
MODBUS on TCP provides a Client/Server communication between devices connected on an Ethernet TCP/IP network. A MODBUS request or response message is encapsulated into a MODBUS/TCP Application Data Unit (ADU) to be carried over a TCP/IP network. All MODBUS messages are sent via TCP to registered port 502.
|
Refer to the Configuring MODBUS TCP chapter of the Cisco Industrial Ethernet 4000 Series Switch Software Configuration Guide for IE 2000 and IE 3000 MODBUS TCP information. |

■OSPF and EIGRP protocol support (IE 3000, IE 3010, and IE 4000) ■PRP interface support (IE 4000) |
This section describes the following system requirements for Cisco IOS Release 15.2(4)EA:
Note: IE 2000U does not support Express Setup or Device Manager.
■1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
■1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
■16 GB available hard disk space (32-bit) or 20 GB (64-bit)
■PC with Windows 7, or Mac OS 10.6.x
■Web browser (Internet Explorer 9.0, 10.0, and 11.0, or Firefox 32) with JavaScript enabled
■Straight-through or crossover Category 5 or 6 cable
Express Setup verifies the browser version when starting a session, and it does not require a plug-in.
These are the procedures for downloading software. Before downloading software, read these sections for important information:
■Finding the Software Version and Feature Set
■Upgrading a Switch by Using the CLI
The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. A subdirectory contains the files needed for web management. The image is stored on the compact flash memory card.
You can use the show version privileged EXEC command to see the software version that is running on your switch. The second line of the display shows the version.
You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images stored in flash memory. For example, use the dir flash: command to display the images in the flash memory.
The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file contains the Cisco IOS image file and the files needed for the embedded device manager. You must use the combined tar file to upgrade the switch through Express Setup. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.
Cisco IOS Software Image Files lists the filenames for this software release.
Note: If you download the IP services image and plan to use Layer 3 functionality, you must use the Switch Database Management (SDM) routing template. To determine the currently active template, enter the show sdm prefer privileged EXEC command. If necessary, enter the sdm prefer global configuration command to change the SDM template to a specific template. For example, if the switch uses Layer 3 routing, change the SDM template from the default to the routing template. You must reload the switch for the new template to take effect.
Before upgrading your switch software, make sure that you archive copies of both your current Cisco IOS release and the Cisco IOS release to which you are upgrading. Keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and verified that the new Cisco IOS image works properly in your network.
Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for information:
http://www.cisco.com/en/US/prod/collateral/iosswrel/ps8802/ps6969/ps1835/prod_bulletin0900aecd80281c0e.html
You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command.
Note: Although you can copy any file on the flash memory to the TFTP server, it is time consuming to copy all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and archive it on an internal host in your network.
You can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP server by using the tftp-server global configuration command.
This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image.
Note: Make sure that the compact flash card is in the switch before downloading the software.
To download software, follow these steps:
1. Use Cisco IOS Software Image Files to identify the file that you want to download.
2. Download the software image file. If you have a SMARTNet support contract, go to this URL, and log in to download the appropriate files:
http://software.cisco.com/download/navigator.html
For example, to download the image for an IE 2000 switch, select Products > Switches > Industrial Ethernet Switches > Cisco Industrial Ethernet 2000 Series Switches, then select your switch model. Select IOS Software for Software Type, then select the image you want to download.
3. Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP server is properly configured.
For more information, see the “Assigning the Switch IP Address and Default Gateway” chapter in the applicable document listed in Methods for Assigning IP Information.
4. Log into the switch through the console port or a Telnet session.
5. (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC command:
For more information about assigning an IP address and default gateway to the switch, see Methods for Assigning IP Information.
6. Download the image file from the TFTP server to the switch.
If you are installing the same version of software that currently exists on the switch, overwrite the current image by entering this privileged EXEC command:
–The /overwrite option overwrites the software image in flash memory with the downloaded one.
–The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.
–For // location, specify the IP address of the TFTP server.
–For / directory / image-name .tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive.
This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch:
You can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option.
You can assign IP information to your switch using the methods shown in Methods for Assigning IP Information.
We recommend that you review this section before you begin working with the switch. These are known limitations that will not be fixed, and there is not always a workaround for these issues. Some features might not work as documented, and some features might be affected by recent changes to the switch hardware or software.
Symptom CIP V4Router object does not display some metrics that show run | i route displays.
Conditions Applies to all switches that have routing.
Workaround There is no workaround for this issue.
Symptom SFP types SFP-GE-L and GLC-EX-SMD sometimes generate Rx power high warning without significant traffic.
Conditions Insert SFPs ( SFP-GE-L and GLC-EX-SMD) into CGS 2520. You can sometimes observe that the Rx power high warning syslog message is generated at every monitoring interval.
If snmp-server enable trap transceiver is configured, a trap is also generated.
Workaround There is no workaround for this issue. The SFPs could have gone bad or the optical cable is bad. Observe the SFPs, cable and traffic, and if you find issues replace the SFPs.
There is no functionality issue observed under this condition. This seems to be a false positive.
Symptom CPU protection and dot1x are mutually exclusive. When enabled, these features work fine. When the IE 2000U or CGS 2520 have TrustSec configured to work with ISE, dot1x fails to authenticate.
Conditions CPU protection is enabled.
Workaround Disable CPU protection by running the following command: no policer cpu uni all
Symptom show cip object v4router 0 does not display correct routes in some scenarios.
Conditions If you configure a cip unsupported route, for example, ip route 0.0.0.0 0.0.0.0 fa1/1 172.27.168.129, the route will not be displayed properly in the sh cip object v4router command output. All following routes (including supported routes such as ip route 0.0.0.0 0.0.0.0 fa1/1 or ip route 0.0.0.0 0.0.0.0 vlan1) also will not be displayed properly. Applies to all switches that support VLAN configuration and CIP features.
This section addresses the open and resolved caveats in this release and provides information on how to use the Bug Search Tool to find further details on those caveats. This section includes the following topics:
Symptom When a port gets congested, classes with a larger queue-limit size are not receiving more frames per second than the classes with a smaller queue-limit size.
Conditions This issue occurs on the IE 4000 when queue-limit sizes are configured unequally in classes.
Workaround There is no workaround for this issue.
Symptom The system allows you to configure more than 16 routes, but they are not visible in the ip route table.
Conditions On an IE 2000 with ip routing enabled, configure more than 16 routes. They are not visible in the ip route table or in show running-configuration. There is no error/warning message when you exceed the 16 route limit. Functionally, there is no impact.
Workaround There is a CLI error message when the maximum number of static routes is exceeded. To see this error message, set the following debugging CLI: debug ip routing static db. When too many routes are configured, you will see the following messages on the console:
Symptom In-line editing becomes unresponsive on the Device Manager Port Thresholds page on IE 2000, IE3000 and IE4000 switches.
Conditions Editing a field too quickly can cause in-line editing to become unresponsive.
Workaround Editing the box repeatedly works if the user waits one or two seconds for Device Manager to push the update to the device.
Symptom BX-40-DAI Description is shown as DA.
Conditions On the IE 2000, IE 3000, and IE 3010, the command show inventory PID on all SFP-pluggable ports with DA-I connected displays the SPF as DA.
Workaround There is no workaround for this issue.
Symptom On the IE 3010, the GE port shows speed as 100Mbps when another GE port is connected.
Conditions This issue occurs when the user changes media between SFP and RJ45 on the same combination interface.
Workaround Issue a shut and no shut on the interface.
Symptom Not able to configure the input alarm 3 and 4 in CGS 2520 and IE 3010 devices from the CLI (Relay, Notifies, and Syslog options).
Conditions Input alarms 3 and 4 appear to be enabled in show alarm settings output but the settings are not retained after reloading the device.
Workaround There is no workaround for this issue.
Symptom The PRP LED did not light up correctly. Observed anomalies in PRP LED in the events below:
Conditions Impacted platform: IE4K
1. Issue a shut/no shut on logical PRP interface (interface prp-channel 1|2).
2. Unplug and plug in cables for uplink ports.
3. Certain sequence issues observed with issuing shut/no shut on logical interface PRP-channel 1 followed by logical interface PRP-channel 2 and vice versa.
Workaround There is no workaround for this issue.
Symptom Inconsistent show license output.
Conditions This issue occurs in the output of show license and license boot level on IE2000 PIDs that do not support Lanlite, IPLite, or Enhanced Lanbase licenses.
Workaround If you set a license level (based on the list displayed in show license), after reload, if the license does not take effect (based on show license output), verify the license support for that SKU instead of relying on show license output.
Symptom On the Cisco IE 2000 and IE 3000, the GetAttList time sync obj 0x43 Reply sequence is inconsistent with the request.
Conditions Get Attributes List was executed against the time sync object in the IE switches. The sequence was explicitly specified with attributes of variable size at the end in order to simplify parsing the reply. While the CIP specification does not explicitly require that the reply follow the sequence of the request, this is the typical (and therefore expected) behavior in released products so far observed.
The initial sequence attempted was
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 18, 19, 20, 27, 28, 12, 13
However the reply sequence received was
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 18, 19, 20, 27, 28
To verify this, a get attributes list with sequence was attempted
5, 4, 3, 2, 1, 6, 7, 8, 9, 10, 11, 18, 19, 20, 27, 28, 12, 13
However the reply sequence received was
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 18, 19, 20, 27, 28
Workaround There is no workaround for this issue.
Symptom Logging out of Device Manager in the IE browser terminates all tab sessions. The user must log in again to any web application sessions that were terminated.
Conditions This issue occurs only with the IE browser.
Workaround Use the Firefox browser.
Symptom MRP convergence time is longer with multicast traffic than it is with unicast traffic.
Conditions This issue occurs on the IE 2000 with multicast traffic in an MRP ring. Currently, 10 multicast groups are supported for an MRP ring.
Workaround There is no workaround for this issue.
Symptom A device connected to a switch is not able to calculate the Peer Delay.
Conditions This issue occurs when the port-type uni configuration is applied to a port, on any platform that supports the port-type uni configuration (CGS2520, IE2000U, IE4000, or IE5000).
The PDel messages share the 01-80-C2-00-00-0E destination MAC address with a variety of other hop-by-hop protocols. The port-type uni command causes the switch to drop all messages sent to the 01-80-C2-00-00-0E destination MAC, including the PDel messages.
Workaround Set the port-type to NNI.
Symptom The MRP Manager blocked port shows the link up/LED color as flashing green (IE 2000). The LED should be solid amber/red instead.
Conditions When the MRP Ring is open, one of the ports is blocked. LED corresponding to the blocked MRP port should not have a flashing green light.
Workaround There is no workaround for this issue.
Symptom The MRP Manager blocked port shows STP in forwarding mode (IE 2000).
Conditions You can observe this issue when the MRP Manager port status is blocked, and you display the STP status for the port.
Workaround Use show mrp ring 1 (no-profinet mrp mode) or show profinet mrp ring 1 (profinet mrp mode) to display MRP port information.
Symptom Interface link flaps occurred on the IE 4000 with use of aggressive lsl-age timer under REP port configuration.
Conditions This issue occurs in a REP Ring with three or more nodes with lsl-age timer set to 120 msecs and after a period of a few minutes to a couple of hours.
Another side affect could be a malloc failure (CAM flush) with repeated link flaps which may cause the switch to crash.
Workaround Increase rep lsl-age timer to a value greater then 120 msec. Recommended value is 3000 msec.
Symptom When updating from Release 15.2(3)E to 15.2(4)E there is a problem with the GSD file (IE 2000).
Conditions Cisco IOS updates only, when going from 15.2(3)E to 15.2(4)E.
Workaround Downgrade to Release 15.2(2)E GSD before upgrading to 15.2(4)E.
Symptom Trace back messages are seen after reloading the IE3010 SKU.
Conditions This issue occurs on SKU IE-3010-16S-8PC only when 100FE SFPs are inserted in all 16 FE SFP and 2 Gigi SFP slots, with loopbacks created using all of them, and the device is reloaded during the boot up process.
Workaround There is no workaround for this issue.
Symptom In Device Manager, on the Configure > Security > ACL page, when you attempt to export ACLs and the combined number of access control entries (ACEs) is more than 10, the operation fails and an error message appears.
Conditions This issue occurs on the IE 3000.
Workaround Export ACLs in multiple operations so that the total number of ACEs in each operation does not have more than ten ACEs.
Symptom In Device Manager on the Configure > Spanning Tree > STP Settings Port Fast tab, Device Manager shows both BPDU Filtering and BPDU Guard as enabled.
Conditions This issue occurs on the IE 2000, IE 3000, and IE 4000 in Device Manager only. If either BPDU Guard or BPDU Filtering is enabled, Device Manager displays both features as enabled. By design, both BPDU Guard and BPDU Filtering cannot be configured at the same time.
Workaround You can verify the configuration using the CLI command show run | in bpdu.
Symptom On the IE 4000 in Device Manager, changing between IP assignment modes deletes the static IP address.
Conditions Steps to reproduce:
1. Launch the device in a browser.
2. Select Configure > Network > VLAN Management.
3. Add a VLAN with a static IP address and save it.
4. Edit the same VLAN and switch between IP assignment modes (No IP Address, Static, and DHCP).
5. The created static IP address is deleted.
Workaround Manually input the static IP address again.
Symptom On the IE 4000, igmp configurations under interface port-channel20 are not removed when the interface changes to a layer2 switch port and then back to layer3 port.
Conditions Steps to reproduce:
1. Configure igmp under layer3 interface po22.
2. Change interface po22 to a layer2 switchport.
igmp configurations are removed from the interface as soon as it becomes a layer2 interface.
3. Change interface po22 back to a layer3 interface.
The script expects igmp configurations to not be shown under interface change back to layer3 interface.
Workaround There is no workaround for this issue.
Symptom Siemens TIA Portal V12 may encounter a software application crash during an upgrade of the GSD via TIA Portal V12 from version dated V2.3-20140212.XML to IOS bundled GSD V2.31-20150807.XML.
Conditions The software crash occurs on the IE 2000 when upgrading GSD using the TIA GUI.
Workaround Remove the older GSD and restart from scratch to build Hardware for TIA12, or use the older GSD from IOS release 15.2(2)E.
Symptom On Cisco IE 3010 and CGS 2520 switches using redundant power supplies (2x PSUs), a syslog message may be seen right after the switch is power cycled or reloaded:
“%ENVIRONMENT-3-POWER_ERROR: PSU x model is not supported”
Conditions This issue occurs when redundant power supplies are installed.
Workaround The syslog does not affect any functionality of the system and does not appear any time after its first appearance after a reload. You can use the CLI command show env all to verify that power supplies are functioning normally.
Symptom On the IE2000, IE3000, and IE4000, when the host name is changed to other than the default name through the CLI, then the DUT is reloaded without saving the configuration and deleting other configuration files. The switch does not boot up with the default hostname but instead boots up with the changed hostname.
Conditions This issue occurs when PROFINET is enabled and then is disabled, and then the hostname is set to the default name.
Workaround There is no workaround for this issue.
Symptom On IE platforms, Flex-Link failover time could be around 700msec when using Gigabit Ethernet ports.
Conditions Steps to reproduce:
1. Configure two Gig links on the IE switch as flex links.
2. Shut a member link and wait for the traffic to switch over to the other link. Failover time of around 700 msec is seen.
Workaround Use Fast Ethernet ports to implement Flex-Link.
Symptom .save files accumulate in the flash folder when a new image is upgraded from CLI.
Conditions This issue occurs on the IE 2000 after upgrading the image on sdflash: and then selecting Yes to the Device Manager prompt “Switch software has been updated. Synchronize the new software between SD Card and Onboard Flash?”
Workaround Delete the.save files from flash, after the ios-image sync between sdflash and flash is complete, as follows:
switch# del /f /r flash:< image name.save >
Symptom The OSPF virtual link authentication type is configured as MD5 in the Cisco IOS CLI, but it is displayed as Password in Device Manager on the IE 4000.
Conditions Steps to reproduce:
1. Launch the device in a browser.
2. Use the Cisco IOS CLI to configure the OSPF virtual link authentication type as MD5.
3. Observe that in Device Manager Configure > Routing Protocols > OSPF, the Virtual Link tab, Password is shown as the authentication type instead of MD5.
1. Configure the virtual link from DM, with MD5 as authentication type. Specify MD5 key id and MD5 key and submit.
2. Verify configurations using the command show running-config | inc ospf < id >
Symptom On the IE 4000, Device Manager does not allow you to enter the Source/Destination Ports and Source/Destination Operator when creating Extended IP ACL lists, after first creating the ACL using the CLI.
Conditions Steps to reproduce:
1. Create an Extended IP numbered ACL from the Cisco IOS CLI (for example, 2699):
2. Launch the device in a browser.
3. Select Configure > Security > ACL.
4. On the ACL List page, add an ACE with Source Type Network.
5. Observe that all other fields can be configured except Source Operator, Source Port, Destination Operator, and Destination Port.
Workaround Re-edit the created Extended IP ACLs to add source and destination ports.
Symptom On the IE 3000, changing the Host Name in Device Manager Express Setup causes a Profinet notification to appear.
Conditions Steps to reproduce:
1. Launch the device in a browser.
2. Select Admin > Device management > Express setup.
3. Change the Host Name and click on Submit.
4. Observe that a Profinet notification appears.
Workaround Click OK and the host name change is accepted.
Symptom On the IE 2000 in Device Manager, after the Locate Switch configuration changes, the Prompt to Sync notification in Dashboard is unreadable.
Conditions This issue occurs when Locate Switch is enabled and disabled, and Prompt to Sync is enabled.
Workaround In Admin > File Management > Sync under the Auto Sync tab, disable Prompt to Sync.
Symptom On all IE switches, restarting the switch in Device Manager without saving the running configuration saves the running configuration anyway.
Conditions Steps to reproduce:
1. Make some configuration changes using the CLI and do not save them; for example, create some VLANs.
2. Navigate to Admin > Device Management > Restart/Reset page.
3. Select the option to Restart the switch without saving running configuration.
4. After restarting the switch observe that the device is reloaded with the saved running configuration. (The configuration changes made in Step 1 are present in the running configuration).
Workaround Use the CLI to reload the switch without saving the running configuration.
Symptom PROFINET requires the following manually configured lldp settings to function and may encounter frequent disconnects without these settings (IE 2000).
lldp timer: 5
lldp holdtime: 20
Conditions When a PROFINET session connects, IO devices will transmit lldp packets every 5 sec and the holdtime will be 20 sec.
Workaround Manually configure the lldp advertise (lldp timer) and holdover (lldp holdtime) timers for PROFINET through CLI on the switch as follows:
switch# conf t
switch# lldp timer 5
switch# lldp holdtime 20
switch# end
Symptom In Device Manager online help, descriptions are missing for the Reset and Reset All buttons in NAT Statistics.
Conditions This issue exists on all IE switch platforms in Device Manager online help under Monitor > Statistics > NAT Statistics.
Workaround There is no workaround for this issue.
Symptom The alarm facility power-supply rps command, which enables an alarm for the RPS, is accepted and applied in the CLI but is not added to the running configuration file.
Conditions This issue occurs on the CGS 2520 running the 15.2(3)EA image and using the alarm-facility feature.
Workaround Verify that the actual functionality works. Be aware that show running-config will not display the RPS alarm information and/or the RPS alarm configuration will not survive reload. Note that this is not related to a customer alarm-profile (default).
Symptom Ping fails when cts dot1x is configured and the SAP mode is configured with no-encap. Dot1x is authenticated, interfaces are up, and CDP is fine, but the peer SVI does not respond to ping.
Conditions This issue occurs on the IE 4000 when the sap mode in use is no-encap.
Workaround Use gcm-encrypt, gmac or null modes.
Symptom Inserting GLC-FE-T-I SFP puts FE ports of IE2000 unit in err-disable state.
Conditions The issue affects certain IE2000 SKU types on which the issue is always present. There are no pre-conditions.
IE-2000-16TC-L (on both uplink and downlink)
IE-2000-16TC-B (on both uplink and downlink)
IE-2000-16TC-G-L (on downlink)
IE-2000-16TC-G-E (on downlink)
IE-2000-16TC-G-E-U (on downlink)
IE-2000-16TC-G-X (on downlink)
Symptom When booting a switch from sdflash, no cdp enable is added to the port-channel members. When booting a switch from flash, the issue is not seen.
Conditions This issue is seen with all released IE 2000 images: 15.0 and 15.2.
Workaround This issue is resolved in Cisco IOS Release 15.2(4)EA.
For previous releases, use one of these workarounds:
Workaround 1: Enable cdp after the switch boots up from sdflash:
Workaround 2: Boot the switch from flash:
Symptom Poor clock synchronization with grandmaster.
Conditions This issue occurred on the IE 2000U during normal operation, when PTP was configured in Power Profile mode.
Workaround This issue is resolved in Cisco IOS Release 15.2(4)EA.
Symptom IE 3010 and CGS 2520 Temperature and Power monitor SNMP status report incorrectly.
Conditions This issue occurred on the IE 3010.
Workaround This issue is resolved in Cisco IOS Release 15.2(4)EA.

This section includes the following late updates to documentation for IE switches:
The Cisco IE 3010 Switch Software Configuration Guide incorrectly states that the network-policy command is supported on the IE 3010. The IE 3010 does not support this command.
This issue is in Cisco IE 3010 Switch Software Configuration Guide Release 12.2(53)EZ, 15.0(2)SE1, or later. (CSCuw22362)
Note: IE 2000U does not support Express Setup or Device Manager.
Express Setup has three options to meet the needs of different installer roles. You select an option based on how long you press the Express Setup button.
■Short press mode—You want to use the existing Express Setup method.
The existing Express Setup behavior has improved failure LED indication.
■Medium press mode—You are installing a switch into an already running environment with certain services available (DHCP) or you want to have the device receive an IP address without using Device Manager.
■Long press mode—You are confident and knowledgeable in the use of Cisco IOS CLI and can configure the switch directly using a console cable.
Express Setup Modes summarizes Express Setup for each mode.
If you need to physically connect or disconnect ports or move a device in a group of similar devices, the locate switch feature helps you to identify the specific device in the group.
The locate-switch command (also available in Device Manager as a check box on the Dashboard page) has the following actions when activated:
■The EXP/Setup indicator LED blinks green to visually notify you that the locate-switch command has been enabled.
–CLI command to enable: Switch# locate-switch
–CLI command to disable: Switch# no locate-switch
■The EXP/Setup indicator LED blinking rate is faster to easily distinguish from the EXP/Setup indicator LED pattern while in Express Setup short press mode.
■The EXP/Setup indicator LED will continue the above pattern for 60 minutes or until the locate-switch command is deactivated.
Note: The locate-switch command is also available through the supporting Add-On Profile (AOP) (through the Switch CIP interface).
The locate-switch command is a volatile command and will not be saved or displayed in running or startup configuration.
