New Features in Cisco IOS Release 15.2(3)E3
Cisco IOS Release 15.2(3)E3 includes one new feature, Hardware Watchdog Reset.
Hardware Watchdog Reset
The expected behavior on the switch when there is an IOS software problem is for the switch to crash, save the information that helps software engineers debug the crash, and then reload. However, there can be rare occurrences of the switch hanging without crashing. Hangs are very hard to reproduce and even harder to fix because there is no trace of what caused the hang. Following are some of the symptoms when the switch hangs:
■Switch becomes totally unresponsive to the CLI
■Switch does not save any crash information
The switch not reloading is a very serious issue, especially for IoT deployments in remote and sometimes hard to reach locations where sending personnel to reload the box is expensive, time consuming, and leads to the system being rendered unusable for that time.
The Hardware Watchdog Reset feature causes the switch to reload if IOS software is unresponsive for a certain period of time (5 minutes). The CPU Hardware Watchdog ensures that the switch reloads if software is hung for whatever reason.
System Requirements
This section describes the following system requirements for Cisco IOS Release 15.2(3)E3:
Express Setup Requirements
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.
Upgrading the Switch Software
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
Finding the Software Version and Feature Set
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.
Deciding Which Files to Use
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.
Archiving Software Images
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.
Upgrading a Switch by Using the CLI
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.
Note: See Upgrading IOS and FPGA on the Ethernet Switch Module (ESM) for ESM software upgrade procedure.
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 the URL below, 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:
This command untars/unzips the file. The system prompts you when it completes successfully.
–The /overwrite option overwrites the software image in flash memory with the downloaded one.
–If you specify the command without the /overwrite option, the download algorithm verifies that the new image is not the same as the one on the switch Flash device. If the images are the same, the download does not occur. If the images are different, the old image is deleted, and the new one is downloaded. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message is displayed.
–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 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. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message is displayed.

Limitations and Restrictions
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 Unsupported VLAN v4r cip object configuration causes issues on the IE 2000.
Conditions If you configure a route with a VLAN interface as the next hop, it affects the display of other routes in the v4r output.
Workaround Remove all VLAN routes in order to view the routes configured after the VLAN v4r configuration. CIP does not support VLAN for static routes.
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.
Caveats
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:
Open Caveats
Symptom In-line editing becomes unresponsive on the Device Manager Port Thresholds page on IE 2000 and IE 3000 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 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 On the IE 2000, sometimes a memory leak can be seen originating from psecure_vlan_info_find.
Conditions The leak is occasionally seen when a user tries to enable port-security with a duplicate MAC address and receives an error.
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.
Resolved Caveats
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 Poor clock synchronization with grandmaster on the IE 2000U.
Conditions This issue is seen during normal operation, when PTP is configured as power profile.
Workaround This issue is resolved in Cisco IOS Release 15.2(3)E3.
Symptom CGS 2520 crashes and reloads when executing the command: # sh policy-map control-plane ?
Conditions This issue occurs during normal operation.
Workaround This issue is resolved in Cisco IOS Release 15.2(3)E3.
Symptom The network-policy profile command is not supported on the IE 3010 in this release and earlier 15.x and 12.x Cisco IOS releases.
Conditions Entering the network-policy profile command on an IE 3010 indicates that it is an Unrecognized command.
Workaround This issue is resolved in this release and the command is supported on IE 3010.
