MAC Filter Match Criteria
dot1p
Syntax dot1p ip-value [ mask ]
no dot1p
Context config>filter>mac-filter>entry
Description
Configures an IEEE 802.1p value or range to be used as a MAC filter match criterion.
When a frame is missing the 802.1p bits, specifying an dot1p match criterion will fail for the frame
and result in a non-match for the MAC filter entry.
The no form of the command removes the criterion from the match entry.
SAP Egress
Egress dot1p value matching will only match if the customer payload contains the 802.1p bits. For
example, if a packet ingresses on a null encapsulated SAP and the customer packet is IEEE 802.1Q or
802.1p tagged, the 802.1p bits will be present for a match evaluation. On the other hand, if a customer
tagged frame is received on a dot1p encapsulated SAP, the tag will be stripped on ingress and there
will be no 802.1p bits for a MAC filter match evaluation; in this case, any filter entry with a dot1p
match criterion specified will fail.
Default
no dot1p
