Identify a suspect line card
Last restart reason
If a line card restarted for some reason (automatically or manually), the show linecard command output
includes the reason for the restart. The following table shows the reasons displayed in the output and their
corresponding causes.
Step Task Command Mode
1 Capture the link status view from a line card. show hard linecard
{0-13 | all} port-set all
tsf link-status
EXEC Privilege
This example shows the view from line card 2
FTOS# show hardware linecard 2 port-set all tsf link-status
Status Of S3 Links(Channel) From LC Slot 2 To All SFMs
Number Of Links Failed : 10
Bit Map Of Failed Links : [PP-0 = 0x3FF00000] [PP-1 = 0x3FF00000]

DOWN}
{SFM-1 <--> PP-1 DOWN} {SFM-2 <--> PP-1 DOWN} {SFM-3 <--> PP-1
DOWN}
{SFM-4 <--> PP-1 DOWN}
2 Capture the link status view from the SFMs show hard sfm allport-set all tsf
