NOTE: You must type in both bytes, otherwise the software will fill the field, left justified with a 00. Refer to RFC
1042 for a complete listing of SAP numbers.
SNAP is defined as an IEEE 802.3 frame with the SSAP, DSAP, and control field set to AA, AA, and 03.
Immediately following these is a five-byte SNAP header. The first three bytes in this header are not used by the
MAC filters. However, the next two bytes usually are set to the EtherType, so you can define the EtherType inside
the SNAP header that you want to filter on.
The eq | gt | lt | neq argument specifies the possible operator: eq (equal), gt (greater than), lt (less than) and neq
(not equal).
The <frame-type> argument is a hexadecimal number for the frame type. For example, the hex number for ARP
is 806.
Syntax: mac filter log-enable
Enables logging for filtered packets.
Syntax: mac-filter-group <filter-list>
Applies MAC filters to a port.
NOTE: Remember that the filters must be applied as a group. For example, if you want to apply four filters to an
interface, they must all appear on the same command line.
