Maintaining SF Ms
The router can have a Switching and Forwarding Module (SFM) in each of the slots
labeled
SFM 0 through SFM 3 at the rear of the chassis, as show n in Figure 3.
To maintain the SFMs, perform the following procedures regularly:
Check the LEDs on the SFM faceplates. The green LED labeled OK lights
steadily when an SFM is functioning normally. For more information, see
“SFM Components” on page 20.
Issue the CLI show chassis s fm command to check the status of the SFMs. The
following sample output is for a router with four SFMs installed:
user@host> show chassis sfm

For more detailed output, add the detail option. The following example also
specifies a slot number (
