Maximum Reflexive ACL Entries

Hi folks

We are facing a problem which might have to do with our reflexive ACLs.

We currently have about 4'000 entries triggered by the reflexive ACLs.

Is there a limitation in the number of entries?

We have a 6509 with SupII and MSFC/PFC2

Thanks!

Regards

Stefan

Re: Maximum Reflexive ACL Entries

for sup1A

Reflexive ACL has a limit of 512 in CAT 6K in hardware, If you exceed the limit a message (propbably "TCAM Full") is expect to come, if you exceed, rest of the RACL will be taken care in software as only 512 region is reserved in hardware for IOS reflexive ACL which need hit count

In sup2/sup720, there is a different mechanism to do reflexive ACLs, and the support 32K/64K/230K for PFC2/PFC3A/PFC3BXL.

Same deal if RACL can't be installed in the hardware then RACL are switched to software
