Restart the SFM
To restart an SFM, use the following command:
user@host> request chassis sfm slot slot-number restart
user@host> request chassis sfm slot 0 restart
Restart initiated, use "show chassis sfm" to verify
user@host> show chassis sfm
Temp CPU Utilization (%) Memory Utilization (%)
Slot State (C) Total Interrupt DRAM (MB) Heap Buffer
0 Ready 0 0 0 0 0 0
1 Online 38 1 0 64 8 46
2 Offline --- Unresponsive ---
3 Online 39 1 0 64 8 46
The command output shows that the SFM restart has been initiated. On the M160 router,
the command output indicates to use the show chassis sfm command to verify that the
SFM has been restarted. The SFM status information shows that the SFM is ready and
that the status values are 0 for approximately 5 seconds until the SFM is active.
