URM Configuration
Tip Configuring the URM requires previous knowledge of both switch software and Cisco IOS software.
Refer to both switch software and Cisco IOS documentation while configuring the URM (see the
“Accessing User Documentation” section on page xii).
Initial URM configuration differs from other IGX cards because you must perform configuration tasks
by accessing two different software programs through two different CLIs.
Depending on your network setup, you can perform initial configuration either remotely through remote
router configuration (RRC—see the “Initial URM Configuration Using RRC” section on page 2-96) or
through a direct connection between your terminal and the URM card (made through the CON port on
the back card—see the “Initial URM Configuration Using the Console Port” section on page 2-93).
Initial URM Configuration Using the Console Port
If you do not have access to a TFTP server, or wish to configure the URM through a direct connection,
use the following procedure:
Step 1 Verify that the back and front cards are properly seated by checking the front card faceplate’s active
(ACT) LED (see Figure 2-42). If the LED is on, the cards are properly seated and the URM is powered
on.
Step 2 Verify that the URM is in standby with the switch software dspcds command.
Step 3 (Optional) Verify the following default configuration information with the switch software cnfrtr
command:
• The embedded router serial port is configured as CON.
• The embedded router loads the Cisco IOS configuration from NPM, so will not enter the
Cisco IOS setup utility.
Timesaver Configure both parameters at the same time with the switch software cnfrtr slot n 1 command.
Note If you reconfigure the URM to load the Cisco IOS configuration from NVRAM, the router enters
the Cisco IOS setup utility.
Step 4 Create the internal ATM port with the switch software addport command. The addport slot.1 command
activates the embedded UXM-E and powers on the embedded router.
Note By default, the URM’s internal ATM interface is a UNI port with a maximum bandwidth of
353,208 calls per second (cps) (equivalent to an OC-3 ATM port); the interface cannot be
configured as a NNI port.
