Page 57

Checking the Configuration

For a VIP2, use the following example:

router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. router(config)#

router(config)# interface serial 1/0/0

router(config-if)# crc 32

Ctrl-z

For a Catalyst RSM/VIP2, use the following example:

router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. router(config)#

router(config)# interface serial 0/0

router(config-if)# crc 32

Ctrl-z

To disable CRC-32 and return to the default CRC-16 setting, specify the slot and port address (and the interface port number for a VIP2) and use the no crc 32 command. For complete command descriptions and instructions, refer to the related software documentation.

Note When enabling a 32-bit CRC on an interface, ensure that the remote device is also conﬁgured for a 32-bit CRC. Both the sender and the receiver must use the same CRC setting.

To check the interface conﬁguration using show commands, proceed to the following section, “Checking the Conﬁguration.”

Checking the Conﬁguration

After conﬁguring the new interface, use the show commands to display the status of the new interface or all interfaces, the ping command to check connectivity, and the loopback command to verify the physical interface.

Using show Commands to Verify Status

Use show commands to verify that the new interfaces are conﬁgured and operating correctly:

Step 1 Use the show version command to display the system hardware conﬁguration. Ensure that the list includes the new interfaces.

Step 2 Display all of the current port adapters and their interfaces with the show controllers command. Verify that the new PA-E3 appears in the correct slot.

Step 3 Specify one of the new interfaces as follows:

•show interfaces type slot/port command on Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers

•show interfaces type slot/port-adapter/port on the VIP2

•show interfaces port-adapter/porton the Catalyst RSM/VIP2

Verify that the ﬁrst line of the display speciﬁes the interface with the correct slot number and that the interface and line protocol are in the correct state: up or down.
