Re: FM-2-TCAM_MEMORY error msg

This message means that the access-list that was applied to vlan 888 took up too much memory and caused the TCAM (ternary content addressable memory, is where where layer 2 and layer 3 switching information is maintained. Depending on how much traffic was travelling through the vlan 888, the ACL became too much.

If possible it is always best to try to use outbound ACL's rather than inbound ACL's. Inbound filters are generally more taxing to the systems resources as opposed to outbound filters.

Hope this helps.
