Troubleshooting the Line Card

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.

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 4-5lists 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 4-5	Line Card Configuration Default Values
