The sfm-number variable species an SFM that you want to display link information for.
The all option displays link information for all SFMs in the chassis.
The errors option only displays information for SFM links that are in the DOWN state.
The output of this command can also be ltered using an output modier. To use an output modier, type a vertical bar ( | ) followed by a
space and one of the following parameters:

Syslog messages
The following syslog messages are related to link monitoring:
System: Interface Ethernet 3/1, state down -fabric connectivity down
System: Interface Ethernet 3/1, state up -fabric connectivity up
Trac Manager XPP link monitoring
Trac Manager (TM) XPP link status is checked during the line card boot up time. MP will attempt to recover TM XPP link errors by
executing resets and then keeping reset cards down that fail to recover after 3 resets.
Thus TM-XPP link is monitored at boot-up, and recovery action is performed. This check will be placed in periodic TM XPP link
monitoring to catch link issues at run time and perform appropriate recovery.
This feature is supported for the following line cards:
8x10GbE
20x10-GbE/1GBE (M) / FRU# 53-1003238-xx
20x10-GbE/1GbE (X2) / FRU# 53-1003275-xx
