Universal Router Module
URM Management
URM functionality is not supported by Cisco WAN Manager (CWM), CiscoWorks 2000 (CW2K) or
Cisco Voice Manager (CVM). Therefore, configuration information must be entered through switch
software CLI and Cisco IOS CLI. See the following network management features:
• Initial Cisco IOS configuration on the URM requires you to access the Cisco IOS CLI through the
hard-wired console port on the back card.
• Initial Cisco IOS setup is configured through assignment of an IP address.
• Each installed URM has its own IP address (which also serves as an external IP address).
• IP-based protocols (Telnet, FTP, or TFTP) connect you to the Cisco IOS software; you can connect
through either the internal ATM interface or the Fast Ethernet interfaces on the back card.
• The URM reports its IP address to switch software through ILMI topology discovery onboard the
embedded UXM-E.
• The embedded router is manageable through Cisco IOS CLI.
• The embedded UXM-E is manageable through the switch software CLI.
Note Information regarding card, interface, and connections in the Cisco IOS domain (such as number and
status of the interfaces, call and connections status, and statistics) can be accessed through the Cisco IOS
CLI only.
Managing the Boot Flash Cisco IOS Image
The URM boot Flash image is managed through switch software commands entered at the switch
software CLI. By default, boot Flash memory is configured as read-only. However, the boot Flash
memory can be reconfigured to read-write for Cisco IOS image updates using the following procedure:
Step 1 At the switch software CLI, use the switch software command cnfrtrparm slot 3 y. The terminal
connected to the embedded router displays the following message:
%IPC_URM-6-BFLASH:Boot flash programmed Read/Write from IGX console
Step 2 Update the boot Flash Cisco IOS image using a standard Cisco IOS image update procedure.
Step 3 At the switch software CLI, use the switch software command cnfrtrparm slot 3 n to reconfigure the
boot Flash memory to read-only.
