Filter Configuration Command Reference
566 Router Configuration Guide
The no form of the command removes the criterion from the match entry.
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
Parameters dot1p-value — The IEEE 802.1p value in decimal.
Values 0 to 7
dot1p-mask — This 3-bit mask can be configured using the decimal integer, hexadecimal or
binary format.
To select a range from 4 up to 7 specify dot1p-value of 4 and a dot1p-mask of 0b100 for value
and mask.
Default 7 (decimal)
Values 1 to 7 (decimal)
dsap
Syntax dsap dsap-value [dsap-mask]
no dsap
Context config>filter>mac-filter>entry>match
Description Configures an Ethernet 802.2 LLC DSAP value or range for a MAC filter match criterion.
This is a one-byte field that is part of the 802.2 LLC header of the IEEE 802.3 Ethernet Frame.
The snap-pid field, etype field, ssap and dsap fields are mutually exclusive and may not be part of the
same match criteria.
Use the no form of the command to remove the dsap value as the match criterion.
