Link up/down messages
The Switch Fabric modules (SFM) in a Brocade chassis send a log message when they first become
operational or when they change state between “UP” and “DOWN”. The following is an example of
the message sent when a link first becomes operational (UP) or when it changes state from
non-operational (DOWN) to operational (UP).
Apr 6 10:57:20:E: Fabric Monitoring Link Up : SFM 3/FE 3/Link 37, LP 5/TM 1
The following is an example of the message sent when a link is detected going from operational
(UP) to non-operational (DOWN).
Apr 6 10:56:00:E: Fabric Monitoring Link Down : SFM 3/FE 3/Link 37, LP 5/TM 1
Once a link has been detected as going down and “auto-tune” is disabled or “auto-tune” is enabled
but the link has already been tuned (see
“Auto-tune enhancement” on page 65), it is automatically
shut down by the Multi-Service IronWare software . The following is an example of the message
sent when a link is either brought down automatically or manually using the command described in
“Powering a switch fabric link on or off manually” on page 64.
Apr 6 10:56:00:E: Fabric Monitoring Link Admin Shut Down : SFM 3/FE 3/Link 37, LP
5/TM 1
This contents of the message are defined as described in the following.
Apr 6 10:57:20 :
– The time that the link changed state.
Fabric Monitoring Link Up
– the link went “UP”
Fabric Monitoring Link Down
– the link went “DOWN”
SFM 3
– The switch fabric module (SFM) number
FE 3
– The Fabric Element number
Link 37
– The number of the interconnect between the SFM and the FE
LP 5
– The slot number where the Interface Module (LP) is installed.
TM 1 –
The number of the traffic manager (TM) used in the link.
Access failure messages
The management module attempts to access each fabric element for every poll period (1 second
by default). If the number of access failures in a poll window (default 10 seconds) exceeds the
threshold (3 by default), the management module sends a log message similar to the following:
Apr 6 20:33:57:A:System: Health Monitoring: FE access failure detected on SFM 2/FE
1
The contents of the message are defined as described in the following.
Apr 6 20:33:57:
– the time at which the error threshold was exceeded
FE access failure detected
– the management module failed to access the specified FE
SFM 2
– the switch fabric module (SFM) number
FE 1
– the Fabric Element (FE) number
