Determining the Software Version
You can use the following commands to verify your software version:
-
For a consolidated package, use the show version command
-
For individual sub-packages, use the show version installed command
Upgrading to a New Software Release
To install or upgrade, obtain a Cisco IOS XE Gibraltar 16.12.1a consolidated package (image) from Cisco.com. You can find software images at http://software.cisco.com/download/navigator.html. To run the router using individual sub-packages, you also must first download the consolidated package and extract the individual sub-packages from a consolidated package.
Note |
When you upgrade from one Cisco IOS XE release to another, you may see %Invalid IPV6 address error in the console log file. To rectify this error, enter global configuration mode, and re-enter the missing IPv6 alias commands and save the configuration. The commands will be persistent on subsequent reloads. |
For more information on upgrading the software, see the How to Install and Upgrade the Software section of the Software Configuration Guide for the Cisco 4000 Series ISRs.

Upgrading the ROMMON Version on the Cisco 4000 Series ISR
For information about ROMMON compatability matrix, and ROMMON upgrading procedure, see the ROMMON Compatability Matrix and "ROMMON Overview and Basic Procedures” sections in the Upgrading Field-Programmable Hardware Devices for Cisco 4000 Series ISRs.
Upgrading Field-Programmable Hardware Devices
The hardware-programmable firmware is upgraded when Cisco 4000 Series ISR contains an incompatible version of the hardware-programmable firmware. To do this upgrade, a hardware-programmable firmware package is released to customers.
Generally, an upgrade is necessary only when a system message indicates one of the field-programmable devices on the Cisco 4000 Series ISR needs an upgrade, or a Cisco technical support representative suggests an upgrade.
From Cisco IOS XE Release 3.10S onwards, you must upgrade the CPLD firmware to support the incompatible versions of the firmware on the Cisco 4000 Series ISR. For upgrade procedures, see the Upgrading Field-Programmable Hardware Devices for Cisco 4000 Series ISRs.
Feature Navigator
You can use Cisco Feature Navigator to find information about feature, platform, and software image support. To access Cisco Feature Navigator, go to https://cfnng.cisco.com/. An account on cisco.com is not required.
Limitations and Restrictions
The following limitations and restrictions apply to all releases:
Cisco Unified Threat Defense
The Cisco Unified Threat Defense (UTD) service requires a minimum of 1 to 4 GB of DRAM.
Cisco ISR-WAAS and AppNav-XE Service
The Cisco ISR-WAAS/AppNav service requires a system to be configured with a minimum of 8GB of DRAM and 16GB flash storage. For large service profiles, 16GB of DRAM and 32GB flash storage is required. Also, Cisco ISR-WAAS requires a minimum of 200GB SSD.

Configure the Cellular Back-off Operation
For a router with 3G/4G interface, sometimes service provider network might be busy, congested, in maintenance or in fault state. In such circumstances, service provider network rejects session activation request from the router by returning reject cause code 33 as a response of the activation request. After the router receives the reject cause, the router uses the back-off operation with the pre-defined timer value which could be carrier-specific. While back-off operation is in progress, no new session activation request is sent out from the router. After the back-off period is up, new session activation request is sent out from the router.
Note: There is no command to disable the cellular back-off feature on the router.
The following example shows how to configure the cellular back-off feature to stop continuous session activation requests back to the router:
Router#show cell 0/2/0 all
Profile 1, Packet Session Status = INACTIVE
Profile 2, Packet Session Status = INACTIVE
Profile 3, Packet Session Status = INACTIVE
.
.
.
Success rate is 0 percent (0/5)
Router#show cell 0/2/0 c
Profile 1, Packet Session Status = INACTIVE
Profile 2, Packet Session Status = INACTIVE
Profile 3, Packet Session Status = INACTIVE
RouterCall end mode = 3GPP
RouterSession disconnect reason type = 3GPP specification defined(6)
RouterSession disconnect reason = Option unsubscribed(33)
RouterEnforcing cellular interface back-off
Period of back-off = 1 minute(s)
Profile 4, Packet Session Status = INACTIVE
...
Profile 16, Packet Session Status = INACTIVE
.
.
.
Profile 16, Packet Session Status = INACTIVE
Configure the Router for Web User Interface
This section explains how to configure the router to access Web User Interface. Web User Interface requires the following basic configuration to connect to the router and manage it.
-
An HTTP or HTTPs server must be enabled with local authentication.
-
A local user account with privilege level 15 and accompanying password must be configured.
-
Vty line with protocol SSH/Telnet must be enabled with local authentication. This is needed for interactive commands.
-
For more information on how to configure the router for Web User Interface, see Cisco 4000 Series ISRs Software Configuration Guide, Cisco IOS XE 17.
Entering the Configuration Commands Manually
To enter the Cisco IOS commands manually, complete the following steps:
Before you begin
If you do not want to use the factory default configuration because the router already has a configuration, or for any other reason, you can use the procedure in this section to add each required command to the configuration.
Procedure
Step 1 |
Log on to the router through the Console port or through an Ethernet port. |
Step 2 |
If you use the Console port, and no running configuration is present in the router, the Setup command Facility starts automatically, and displays the following text:
Enter no so that you can enter Cisco IOS CLI commands directly. If the Setup Command Facility does not start automatically, a running configuration is present, and you should go to the next step. |
Step 3 |
When the router displays the user EXEC mode prompt, enter the enable command, and the enable password, if one is configured, as shown in the following example:
|
Step 4 |
Enter config mode by entering the configure terminal command, as shown in the following example.
|
Step 5 |
Using the command syntax shown, create a user account with privilege level 15. |
Step 6 |
If no router interface is configured with an IP address, configure one so that you can access the router over the network. The following example shows the interface GigabitEthernet 0/0/0 configured.
|
Step 7 |
Configure the router as an http server for nonsecure communication, or as an https server for secure communication. To configure the router as an http server, enter the ip http server command shown in the example:
|
Step 8 |
Configure the router for local authentication, by entering the ip http authentication local command, as shown in the example:
|
Step 9 |
Configure the vty lines for privilege level 15. For nonsecure access, enter the transport input telnet command. For secure access, enter the transport input telnet ssh command. An example of these commands follows:
|
