I don't believe that there is anything simpler than `show interfaces | <some regex>` unfortunately. I usually use the following to find where ACLs are applied: show ip interface | include is up|is administratively|is down|Outgoing|Inbound This gives you every interface, no matter the state, then what the Outbound and Inbound ACL's are. For example: LAB-4510-A#show ip interface | include is up|is administratively|is down|Outgoing|Inbound Vlan1 is administratively down, line protocol is down Vlan110 is up, line protocol is up Outgoing access list is not set Inbound access list is VENDOR->INTERNET Vlan140 is administratively down, line protocol is down Outgoing access list is not set Inbound access list is not set Vlan150 is down, line protocol is down Outgoing access list is not set Inbound access list is VENDOR->INTERNET Vlan210 is up, line protocol is up Outgoing access list is not set Inbound access list is not set FastEthernet1 is administratively down, line protocol is down Outgoing access list is not set Inbound access list is not set GigabitEthernet1/1 is up, line protocol is up Outgoing access list is not set Inbound access list is not set GigabitEthernet1/2 is down, line protocol is down Inbound access list is not set Outgoing access list is not set And so on for every interface. ---------- This command works on both Cisco switches and routers. See sample output from a 7200 Router below: LAB-7204-A#show ip interface | include is up|is administratively|is down|Outgoing|Inbound GigabitEthernet0/1 is up, line protocol is up Outgoing access list is not set Inbound access list is not set FastEthernet0/2 is administratively down, line protocol is down GigabitEthernet0/2 is up, line protocol is up Outgoing access list is not set Inbound access list is not set GigabitEthernet0/3 is administratively down, line protocol is down SSLVPN-VIF0 is up, line protocol is up Outgoing access list is not set Inbound access list is not set Loopback0 is up, line protocol is up Outgoing access list is not set Inbound access list is not set Loopback1 is up, line protocol is up Outgoing access list is not set Inbound access list is not set
