Monitoring Link Status

Displaying fabric link status

To display the fabric link status, enter the following command:
MLX#show sfm-links 1
SFM#/FE# | FE link#
----------+-----------+---------+-----------+---------
1 / 1 | 13
1 / 1 | 17
1 / 1 | 14
Syntax: show sfm-links sfm-number | all [ errors ]
The sfm-number variable specifies 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 filtered using an output modifier. To use an output modifier, type a vertical bar ( | ) followed by a
space and one of the following parameters:
• begin - begin output with the first matching line
• exclude - exclude matching lines from the output
• include - include only matching lines in the output
A warning statement is sent if the number of operational links falls below the minimum threshold.
This warning is displayed to warn users that the line rate traffic will not be maintained.
The following table describes the information the show sfm-links command displays.
