Mac Filter Policy Entry Match Criteria - Alcatel-Lucent 7450 Configuration Manual

MAC Filter Policy Entry Match Criteria

The below lists MAC match criteria supported by SROS routers/switches for all types of MAC
filters (normal, isid, and vid). The criteria are evaluated against the Ethernet header of the Ethernet
frame. Support for a given match criteria may depend on H/W and/or filter direction as per below
description. Match criterion is blocked if it is not supported by a specified frame-type or MAC
filter sub-type. It is recommended not to configure a filter in a direction or on a H/W where a given
match condition is not supported as this may lead to undesired behavior.

7450 ESS Router Configuration Guide
frame-type — Entering the frame type allows the filter to match for a specific type of
frame format. For example, configuring frame-type ethernet_II will match only Ethernet-
II frames.
src-mac— Entering the source MAC address allows the filter to search for matching a
source MAC address frames. Operator can optionally configure a mask to be used in a
match.
dst-mac— Entering the destination MAC address allows the filter to search for matching
destination MAC address frames. Operator can optionally configure a mask to be used in a
match.
dot1p — Entering an IEEE 802.1p value allows the filter to search for matching 802.1p
frames. Operator can optionally configure a mask to be used in a match.
etype— Entering an Ethertype value allows the filter to search for matching Ethernet II
frames. The Ethernet type field is a two-byte field used to identify the protocol carried by
the Ethernet frame.
ssap— Entering an Ethernet 802.2 LLC SSAP value allows the filter to search for
matching frames with a source access point on the network node designated in the source
field of the packet. Operator can optionally configure a mask to be used in a match.
dsap— Entering an Ethernet 802.2 LLC DSAP value allows the filter to search for
matching frames with a destination access point on the network node designated in the
destination field of the packet.. Operator can optionally configure a mask to be used in a
match.
snap-oui— Entering an Ethernet IEEE 802.3 LLC SNAP OUI allows the filter to search
for matching frames with the specified the three-byte OUI field.
snap-pid— Entering an Ethernet IEEE 802.3 LLC SNAP PID allows the filter to search
for the matching frames with the specified two-byte protocol ID that follows the three-
byte OUI field.
isid — Entering an Ethernet IEEE 802.1ag ISID from the I-TAG value allows the filter to
search for the matching Ethernet frames with the 24 bits ISID value from the PBB I-TAG.
This match criterion is mutually exclusive with all the other match criteria under a
particular mac-filter policy and is applicable to MAC filters of type isid only. The resulting
mac-filter can only be applied on a BVPLS SAP or PW in the egress direction.
