Create ACE - MAC Extended Window

This window appears when you choose MAC Extended and click Create in the Create ACL window.

Follow these steps to create an ACE for an ACL of the MAC extended type:

  1. In the Keyword list, select an action: permit to permit traffic from specified sources and to specified destinations or deny to deny traffic from those sources and to those destinations.
  2. Enter a source MAC address in the Source MAC Address field.
  3. Choose a filter from the Source Wildcard list: host to specify a particular source MAC address, 0000.00ff.ffff to designate a type mask, or any to designate any source MAC address.
    Restriction: For Catalyst 2950 switches, only the host and any options are supported.
  4. Use the Destination MAC Address field and the Destination Wildcard list as you used the Source MAC Address field and Source Wildcard list. The only difference is that here you are specifying filtering criteria for a destination address.
    Restriction: For Catalyst 2950 switches, destination wildcards are not available.
  5. Enter a value in the CoS (class of service) field that the ACE should be matched against.
    Restriction: On Catalyst 2950 switches, you cannot filter packets based on CoS values.
  6. Enter a value in the LSAP field that the ACE should be matched against.
    Restriction: On Catalyst 2950 switches, you cannot filter packets based on LSAP values.
  7. Choose an EtherType to associate with the Keyword action. Choose Other if you want to enter a specific value.
    Restriction: On Catalyst 2950 switches, the Other option is not supported.
  8. Enter a value in the Other field if you selected Other in the EtherType field.
    Restriction: On Catalyst 2950 switches, the Other field is not supported.
  9. Click OK. An ACE for a MAC extended ACL is created.
