This 48-bit mask can be configured using the following formats:
To configure so that all packets with a source MAC OUI value of 00-03-FA are subject to a
match condition then the entry should be specified as: 0003FA000000 0x0FFFFF000000
Default
0xFFFFFFFFFFFF (exact match)
Values
0x00000000000000 — 0xFFFFFFFFFFFF

Syntax
etype ethernet-type
no etype
Context

Description
Configures an Ethernet type II Ethertype value to be used as a MAC filter match criterion.
The Ethernet type field is a two-byte field used to identify the protocol carried by the Ethernet frame.
For example, 0800 is used to identify the IPv4 packets.
The Ethernet type field is used by the Ethernet version-II frames. IEEE 802.3 Ethernet frames do not
use the type field. For IEEE 802.3 frames, use the dsap, ssap or snap-pid fields as match criteria.
The snap-pid field, etype field, ssap and dsap fields are mutually exclusive and may not be part of the
same match criteria.
“MAC Match Criteria Exclusivity Rules” on page 294
describes fields that are
exclusive based on the frame format.
The no form of the command removes the previously entered etype field as the match criteria.
Default
none
Parameters
ethernet-type — The Ethernet type II frame Ethertype value to be used as a match criterion expressed
in hexadecimal.
Values
0x0600 — 0xFFFF
