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 http://www.cisco.com/go/cfn . 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.

IPsec Traffic

IPsec traffic is restricted on the Cisco ISR 4451-X. The router has the same IPsec functionality as a Cisco ISR G2. The default behavior of the router will be as follows (unless an HSECK9 license is installed):

  • If the limit of 1000 concurrent IPsec tunnels is exceeded, no more tunnels are allowed and the following error message appears:

%CERM-4-TUNNEL_LIMIT: Maximum tunnel limit of 1000 reached for Crypto functionality with securityk9 technology package license.
  • The throughput encrypted traffic supports 250 Mbps.
  • The Cisco 4000 Series ISR does not currently support nested SA transformation such as:

crypto ipsec transform-set transform-1 ah-sha-hmac esp-3des esp-md5-hmac 
crypto ipsec transform-set transform-1 ah-md5-hmac esp-3des esp-md5-hmac 
  • The Cisco 4000 Series ISR does not currently support COMP-LZS configuration.

CUBE–SRTP Calls

Cisco IOS XE Everest release 16.5.1 is not recommended for Cisco Unified Border Element deployment involving SRTP calls.

Encrypted Traffic Analytics Record

When the router is reloaded with large configuration, the router generates a high number of messages for initializing the features in data plane and the Encrypted Traffic Analytics (ETA) record may not be exported. This happens only when the ETA inactive timeout command is configured on the router. To avoid this issue, you can configure the inactive timeout commad after the router reloads.

USB Etoken

USB Etoken is not supported on Cisco IOS XE Denali 16.2.1.

Unified Communication on Cisco 4000 Series ISR

  • For T1/E1 clocking design and configuration changes, For detailed information, see the following Cisco document: T1/E1 Voice and WAN Configuration Guide.

New Features and Important Notes About Cisco 4000 Series ISRs Release Fuji 16.8.1

This section describes new features in Cisco IOS XE Fuji 16.8 that are supported on the Cisco 4000 Series ISRs.

New and Changed Information

New Software Features in Cisco 4000 Series ISR Release Cisco IOS XE Fuji 16.8.1

The following features are supported by the Cisco 4000 Series Integrated Services Routers for Cisco IOS XE Fuji 16.8.1:

Configure the Router for Web User Interface

This section explains how to configure the router to access Web User Interface. Web User Interface require 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.

  • You can use the Cisco IOS CLI to enter the necessary configuration commands. To use this method, see Entering the Configuration Commands Manually.

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:

--- System Configuration Dialog ---
 
Continue with configuration dialog? [yes/no]:

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:

Router> enable
password password
Step 4

Enter config mode by entering the configure terminal command, as shown in the following example.

Router> config terminal
Router(config)#
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 Fast Ethernet 0 configured.

Router(config)# int FastEthernet0
Router(config-if)# ip address 10.10.10.1 255.255.255.248
Router(config-if)# no shutdown
Router(config-if)# exit
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:

Router(config)# ip http secure-server
Step 8

Configure the router for local authentication, by entering the ip http authentication local command, as shown in the example:

Router(config)# ip http authentication local
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:

Router(config)# line vty 0 4
Router(config-line)# privilege level 15
Router(config-line)# login local
Router(config-line)# transport input telnet
Router(config-line)# transport output telnet
Router(config-line)# transport input telnet ssh
Router(config-line)# transport output telnet ssh
Router(config-line)# exit
Router(config)# line vty 5 15
Router(config-line)# privilege level 15
Router(config-line)# login local
Router(config-line)# transport input telnet
Router(config-line)# transport output telnet
Router(config-line)# transport input telnet ssh
Router(config-line)# transport output telnet ssh
Router(config-line)# end
