Explanation The software could not load the VRF routing table into the TCAM because there were
not enough hardware resources available for the operation. Traffic on this VRF will now be routed
in software at reduced forwarding performance.
Recommended Action Reduce the Layer 3 forwarding hardware resource use, by reducing the number
of routes loaded or by reducing the number of VLANs contained within the VRF. When the
hardware requirements are reduced sufficiently, Cisco IOS software automatically reloads the VRF's
routes into hardware. When this happens, the
C4K_L3HWFORWARDING-6-SUCCEEDEDTOLOADVRFROUTINGTABLETOFWDCAM
message appears.
One or more VLANs corresponding to L3 routed ports or SVI could not be set up for
Explanation
redirection because there is insufficient room for more TCAM entries. Ingress IPv4 traffic on these
VLANs will be routed normally. When the hardware requirements have been reduced sufficiently,
the switch will automatically enable redirection for those VLANs.
Reduce the layer 3 forwarding hardware resource utilization, either by
Recommended Action
reducing the number of routes loaded or by reducing the number of VLANs contained within this
WCCP service group. If the redirection is not enabled even after freeing up memory from these
actions, please contact Cisco technical assistance.
The hardware policy-based routing forwarding engine now has sufficient resources to

handle the route map for the specified interface and can now do hardware forwarding of unicast IP
traffic.
