Checking the Configuration

PA-T3 Serial Port Adapter Installation and Configuration

8-14

For a Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series router, use the following

example:

router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

router(config)#

router(config)# interface serial 3/0

router(config-int)# crc 32

Ctrl-z

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

troubleshoot the physical interface.

Using show Commands to Verify Status

Use the 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 the current port adapters and their interfaces with the show controllers

command. Verify that the new PA-T3 serial port adapter appears in the correct slot.
