L3HWFORWARDING Messages
Error Message C4K_L3HWFORWARDING-4-FWDCAMOUTOFSPACEFORVRFROUTINGTABLE: Insufficient
TCAM resources to load VRF [char] routing table. Switching to software forwarding
for this VRF.
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.
Error Message C4K_L3HWFORWARDING-4-FWDCAMOUTOFSPACEFORWCCPREDIRECTION: WCCP Service
Group [char] failed to setup one or more routed ports/SVI for redirection due to
lack of TCAM entries.
Explanation
One or more VLANs corresponding to L3 routed ports or SVI could not be set up for
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.
Recommended Action Reduce the layer 3 forwarding hardware resource utilization, either by
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.
L3HWFORWARDING-6
Error Message L3HWFORWARDING-6-NOLONGERPBRPUNTINGPORT: Sufficient Policy Routing
TCAM space has been found to handle PBR for interface [char] in hardware, no
longer punting to software.
Explanation
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.
Recommended Action This is an informational message only. No action is required.
Error Message C4K_L3HWFORWARDING-6-SUCCEEDEDTOLOADVRFROUTINGTABLETOFWDCAM:
Successfully loaded VRF [char] routing table to TCAM. Switching to hardware
forwarding for this VRF.
Explanation
A VRF that was previously being routed by software is now fully reloaded and hardware
forwarding has resumed. Refer to the
C4K_L3HWFORWARDING-4-FWDCAMOUTOFSPACEFORVRFROUTINGTABLE message for
more information.
Recommended Action This is an informational message only. No action is required.
