FM-2-TCAM_MEMORY: Interface Vlan888 processor memory low programming ingress ACLs.

The system is Cat6509 +

Re: FM-2-TCAM_MEMORY error message

The ACLs on the CAT6000 are programmed in hardware in TCAM (Ternary Content Accessible Memory). By default the Cat6000 uses a BDD algorithm to program the access lists, which is not very efficient. Changing that algorithm to ODM helps in most cases.

(config)#mls aclmerge algorithm odm

(config)#mls aclmerge odm optimizations

Then remove and reapply the access lists and "access-groups" on all the interfaces.

Refer to the following url from more information:
