MAC_LIMIT Messages
Explanation The size of the Layer 3 unicast TCAM entry is not sufficient to implement a feature.
[chars] is the feature name (either Web Cache Communication Protocol [WCCP] or multiple VPN
routing/forwarding [multi-VRF]) that requires the 144-bit TCAM size.
Recommended Action Modify the Switch Database Management (SDM) template to enable the switch
to support the 144-bit Layer 3 TCAM. Use the sdm prefer extended-match, sdm prefer access
extended-match, or sdm prefer routing extended-match global configuration command, and then
reload the switch by using the reload privileged EXEC command.
Error Message L3TCAM-3-TOO_MANY_VRF: Exceed the maximum number of VRF allowed.
Note This message applies only to Catalyst 3550 switches.
Explanation The number of virtual private networks (VPNs) exceeds the number allowed by the VPN
routing/forwarding table on this hardware platform.
Recommended Action Reconfigure your switch to limit the number of VRFs. Do not define (name)
more than seven VRFs with the ip vrf vrf-name global configuration command.
Error Message L3TCAM-4-WCCP_ENABLE: Both VRF and WCCP are enabled, please remove
