in and out ACL on VLAN interfaces

Unanswered Question
Jan 16th, 2008


could you, please explain me direction when ACL is applied on VLAN interface?

For example, ACL applied like "out" on "interface VLAN 8" means that destination address is in VLAN 8 ?



I have this problem too.

It means that ACL is applicated to packet directed out that interface. It applies to packet with destination addressess not in VLAN 8.

I hope this helps.

Best regards.

Actually that's not correct, if you had the following...

interface vlan 8

ip access-group 100 out

...this means that the destination would be addresses in vlan 8.

If you had...

interface vlan 8

ip access-group 100 in

...then addresses in vlan 8 would be sources.
