Power The Sfm On/Off - Dell Force10 C150 Configuration Manual

Task
Execute a manual dataplane
loopback test:
• all-loopback – Both the RPM
and the line card dataplane
loopback test is done.
• rpm-loopback – Only the RPM
dataplane loopback test is done.
This test can be run when the switch
fabric is in either an operational or a
non-operational state.
If the RPM-SFM or line card-SFM loopback test detects an SFM failure, an attempt is made to isolate a
single faulty SFM by automatically walking the SFMs. For this failure case, error messages similar to the
runtime loopback test error are generated.
Note: The dataplane runtime loopback configuration does not apply to this manual loopback test.
In the example in
Figure 61-2. diag sfm all-loopback command Example
FTOS#diag sfm all-loopback
Proceed with dataplane loopback test [confirm yes/no]:yes
SFM loopback test completed successfully.
FTOS#
If the test passes when the switch fabric is down and there are at least (max-1) SFMs in the chassis, then
the system will bring the switch fabric back up automatically. Like the runtime loopback test, the manual
loopback test failure will not bring the switch fabric down.
Note: Line card-SFM loopback test failure, during the manual test, will trigger an SFM walk.

Power the SFM on/off

If you suspect that an SFM is faulty and would like to manually disable it to determine whether any packet
loss or forwarding issues are resolved, execute the following command.
