Service SAP QoS Policy Command Reference
318 Quality of Service Guide
Description This command configures the matching of the first tag that is carried transparently through the service.
Service delimiting tags are stripped from the frame and outer tag on ingress is the first tag after any
service delimiting tags. Outer tag is the first tag before any service delimiting tags on egress. This
allows matching VLAN tags for explicit filtering or QoS setting when using default or null
encapsulations.
On dot1Q SAPs outer-tag is the only tag that can be matched. On dot1Q SAPs with exact match (sap
2/1/1:50) the outer-tag will be populated with the next tag that is carried transparently through the
service or 0 if there is no additional VLAN tags on the frame.
On QinQ SAPs that strip a single service delimiting tag outer-tag will contain the next tag (which is
still the first tag carried transparently through the service.) On SAPs with two service delimiting tags
(two tags stripped) outer-tag will contain 0 even if there are more than 2 tags on the frame.
The optional vid_mask is defaulted to 4095 (exact match) but may be specified to allow pattern
matching. The masking operation is ((value & vid-mask) = = (tag & vid-mask)). A value of 6 and a
mask of 7 would match all VIDs with the lower 3 bits set to 6.
For QoS, the VID type cannot be specified on the default QoS policy.
The default vid-mask is set to 4095 for exact match.

Description Configures an IEEE 802.3 LLC SNAP Ethernet frame OUI zero or non-zero value to be used as a
service ingress QoS policy match criterion.
The no form of this command removes the criterion from the match criteria.
Default none
Parameters zero — Specifies to match packets with the three-byte OUI field in the SNAP-ID set to zero.
non-zero — Specifies to match packets with the three-byte OUI field in the SNAP-ID not set to
zero.
