permit (MAC access-list configuration) Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands After an access control entry (ACE) is added to an access control list, an implied deny-any-any condition exists at the end of the list. That is, if there are no matches, the packets are denied. However, before the first ACE is added, the list permits all packets. For more information about MAC-named extended access lists, see the software configuration guide for this release. Examples This example shows how to define the MAC-named extended access list to allow NETBIOS traffic from any source to MAC address 00c0.00a0.03fa. Traffic matching this list is allowed. Switch(config-ext-macl)# permit any host 00c0.00a0.03fa netbios This example shows how to remove the permit condition from the MAC-named extended access list: Switch(config-ext-macl)# no permit any 00c0.00a0.03fa 0000.0000.0000 netbios This example permits all packets with Ethertype 0x4321: Switch(config-ext-macl)# permit any any 0x4321 0 You can verify your settings by entering the show access-lists privileged EXEC command.
