Troubleshooting the Line Card

Configuring and Troubleshooting Line Card Interfaces

After the person who installed the hardware verifies that the line card is working properly by examining

the LEDs, the network administrator can configure the new interface. These sections provide

information on configuring and troubleshooting the line card:

•Configuration Parameters, page 4-13

•Line Card Interface Address, page 4-14

•Using Configuration Commands, page 4-14

•Basic Line Card Configuration, page 4-14

•Verifying the Transceiver Modules, page 4-15

•Advanced Line Card Troubleshooting, page 4-17

Configuration Parameters

Table 4-5 lists the default interface configuration parameters that are present when an interface is

enabled on a 10-Gigabit Ethernet line card. See Cisco IOS XR software documentation for complete

information about these parameters.

Table 4-4 RSP FAIL and LC FAIL LEDs

RSP FAIL LED

Green Port state is up and a valid physical layer link is established.

Blinking Line activity is occurring. The LED blinks green-amber-green.

Red Port state is up, but there is a link loss or SFP/XFP failure.

Off Port is administratively shut down.

LC FAIL LED

Green Line card has booted properly, and is ready to pass or is passing traffic.

Red Line card has encountered a hardware error, and is not passing traffic.

Off Line card is powered off. The LED might turn off momentarily when switching

between the states described above, although the line card has not powered off.
