VACL Question

Can anybody explain how a VACL works, specifically in the switch architecture?

So far my understanding is that it is a Layer 2 "filter" applied to a VLAN. A VACL is NOT the same as a RACL (router acl). A RACL is used on an actual router interface or an SVI.

Any clarification would be appreciated!

Re: VACL Question

The VACL's are used to filter traffic within a vlan and it has no direction as opposed to RACL's. The match can be either on mac acl or ip acl. The RACL's are used on routed ports same as in case of routers.

Here is a link describing how to configure it and gives some information how it works:

Re: VACL Question

Thanks for your help!

So far I understand there are RACLs, VACLs, and PACLs. Are PACLs only allowed to be strictly used on switchports?

Re: VACL Question

Hi,

Port ACLs access-control traffic entering a Layer 2 interface. The switch does not support port ACLs in the outbound direction (on 3550). You can apply only one IP access list and one MAC access list to a Layer 2 interface.

Hope it helps, rate if does
