ACL Layer3 on FCX

[ Edited ]

I have a trunk port with 3 vlans on it, 11,12,13 which go off to a third party environment.

I have no control over ip addresses allocated to devices on vlan 13 and am worried about conflicts from misconfig by another admin.

I would like to restict incoming traffic to my switch specifically only of vlan13 so that only traffic from is permitted inbound to my vlan13 members.

I am confused by source-guard and standard ACLs.  Source guard appears to be mainly for vlan assignment, so am I right in thinking I need to focus on ACLs?


If so, does this look correct:

enable ACL-per-port-per-vlan

write memory



access-list 13 permit

int e 1/0/39

  per-vlan 13

    ip access-group 13 in
