7100-Series / ACL / Access Control List Limitations


We try to transfer an ACL from a DFE module (with Advanced Licence) to an 7100 (about 300 entries). We can only enter 180 lines, then we're done.

IPV6 Egress ACL = 256

How can we solve the problem (more accepted entries in the ACL)?

Hi,

The limits for ACLs in the 7100 series platform is smaller than in the N-Series. I believe is a hardware limitation.

I am afraid this is FAD (Functions as Designed).

In another client, what I did is convert part of it (if not all) to policies using Policy Manager.

Hope it helps.
but why the switch shows:

IPV4 Rules = 249

or

Chassis limits:Application Limit In use Entry size Total Memory
-------------------------------- --------- --------- ------------ ------------
access-lists 256 9 125K 31.3M
access-list-entries 1000 180 160B 156.4K

and we ended at 180 ACL-entries?
does somebopdy know why the switch shows:

IPV4 Rules = 249

or

Chassis limits:Application Limit In use Entry size Total Memory
-------------------------------- --------- --------- ------------ ------------
access-lists 256 9 125K 31.3M
access-list-entries 1000 180 160B 156.4K

and we ended at 180 ACL-entries?
