Error Message PLATFORM_FBM-4-RESOURCE_CRUNCH: Fallback bridging on bridge-group
[dec] is experiencing a resource crunch. One or more bridge-groups may not be
functional. It will recover automatically when system recovers from resource
crunch. Delete the bridge-group to immediately recover.
Note This message applies only to Catalyst 3750 and 3560 switches.
Explanation Fallback bridging could not be configured properly. The most likely cause is a
TCAM-full condition on at least one stack member.
Recommended Action The switch automatically recovers, but this could take some time. For an
immediate recovery, use the shutdown interface configuration command to disable the port and stop
the traffic flow to the switch. Use the clear mac-address-table dynamic privileged EXEC
command to remove all MAC addresses from the TCAM. Use the no shutdown interface
configuration command to re-enable the port.

This section has the Cisco Express Forwarding (CEF) message.
Error Message PLATFORM_HCEF-3-ADJ: [chars]
Note This message applies only to the Catalyst 3750 and 3560 switches.
Explanation This message appears when an unsupported feature is configured on a switch running
Cisco IOS Release 12.2(25)SE. [chars] is the error message.
Recommended Action Determine if a generic routing encapsulation (GRE) tunnel or the ip cef
accounting global configuration command are configured. Only Distance Vector Multicast Routing
Protocol (DVMRP) tunnels are supported. If the GRE tunnel is configured, remove the tunnel, or
upgrade the switch software to a Cisco IOS release when the GRE feature is needed. If the ip cef
accounting command is configured, remove it by using the no ip cef accounting global
configuration command.
Note Cisco IOS Release12.2(25)SEB2 does not support the ip cef accounting command.
