Configuring the Junos OS to Make an SFM Stay Offline
By default, if you use the request chassis sfm CLI command to take a Switching and Forwarding Module (SFM) offline, the SFM attempts to restart when you enter a commit CLI command. To prevent a restart, you can configure an SFM to stay offline. This feature is useful for repair situations.
To configure an SFM to stay offline, include the sfm statement at the [edit chassis] hierarchy level:
- slot number—Slot number in which the SFM is installed.
- power off—Take the SFM offline and configure it to remain offline.
For example, the following statement takes an SFM in slot 3 offline:
Use the show chassis sfm CLI command to confirm the offline status:
user@host# show chassis sfm
Temp CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt DRAM (MB) Heap Buffer 0 Online 34 2 0 64 16 47 1 Online 38 2 0 64 16 47 2 Online 42 2 0 64 16 47 3 Offline --- Configured power off ---
To bring the SFM back online, delete the edit chassis sfm statement and then commit the configuration.
