Installation Guide

later solve this problem continuously running a software task on the LP that monitors link status. If it detects that if the fabric links
between the traffic manager and the backplane are down, the software shuts down the ports connected to that traffic manager, resulting
in no continuous traffic drop. If all of the following criteria are met, the software brings the ports back up:
∙ all the links come back up
∙ at least 30 percent of the total links are in the "up" state
∙ the port is enabled and there are no additional blocking conditions
Enabling monitoring link status
This feature is included by default in NetIron R05.3.00 and later; no configuration is required to enable it.
Disabling monitoring link status
To disable the link status monitoring feature, enter the following command:
no system-monitoring tm port-control
Displaying fabric link status
To display the fabric link status, enter the following command:
MLX#show sfm-links 1
SFM#/FE# | FE link# | LP#/TM# | TM link# | link state
----------+-----------+---------+-----------+---------
1 / 1 | 13 | 2 / 1 | 13 | UP
1 / 1 | 17 | 2 / 2 | 01 | DOWN
1 / 1 | 14 | 2 / 1 | 01 | UP
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.

This field... Displays...
SFM# The switch fabric module number.
FE# The FE number.
FE link# The number of the interconnect between the SFM and the FE.
LP# The slot number where the Interface module (LP) is installed.
