Packet Forwarding Engine Power Management
You can power on or power off the Packet Forwarding Engines (PFEs) in a running system, or keep a Packet Forwarding Engine powered off when the FPC comes online. The following are a couple of scenarios in which this feature is used.
- When the Packet Forwarding Engine ASIC is malfunctioning.
- To conserve power in case the deployment does not require the full capacity of the system.
To power off a Packet Forwarding Engine, use the following steps:
user@host# set chassis fpc slot-number pfe
pfe-id power off
user@host# commit
You need to apply this configuration to both the Packet Forwarding Engines in an ASIC to be able to commit the configuration.
You can use the show chassis fpc fpc-slot detail command to view the Packet
Forwarding Engine power on/off configuration status. See an example below:
user@router> show chassis fpc 0 detail
