problem on netiron ces 2000

Hi,

does anybody know what can means those statements:

Hi Info7,

     It is saying that you have run out of CAM space, one way this could happen is to have a large amount of ACL's on the ports that are in the same packet process.

CAM can also be allocated into different area to suit different needs.  However I do not have much experance with this and would suggest yo contact the TAC to see what is eating the resources.

CAM partitioning

NetIron CES and NetIron CER devices support CAM partitioning.

The size of the extended ingress IPv6 L4 key is 640 bits. The size of the standard ingress ACL key is 320 bits. In internal TCAM, different sized keys can reside next to each other in the same block. Inexternal TCAM, blocks are allocated for ACLs, and different sized keys cannot reside in the same block. An ingress IPv6 L4 key cannot reside in the same block with other ingress ACLs.

You can configure CAM partition to have an ingress ACL into internal TCAM and an egress ACL into external TCAM. The ingress IPv6 L4 key can reside in the same TCAM with other ingress ACLs, but must reside in a different block in the external TCAM.

You can select one key per interface for the following packet types (port or VLAN).

IPv6 packets

IPv4 and ARP packets

Non-IP packets
