isid
Syntax isid value [ to higher-value ]
no isid
Context config>filter>mac-filter>entry>match
Description This command configures an ISID value or a range of ISID values to be matched by the mac-filter
parent. The pbb-etype value for the related SAP (inherited from the ethernet port configuration) or for
the related SDP binding (inherited from SDP configuration) will be used to identify the ISID tag.
When an isid statement is used in a match criteria the corresponding mac-filter can be applied only on
the egress side of a SAP/SDP binding. In order to be able to use an isid match criteria one needs to set
the mac-filter type attribute to isid. Once this configuration is performed only ISID match criteria are
allowed in the mac-filter.
The no form of this command removes the ISID match criterion.
Default
no isid
value — Specifies the ISID value, 24 bits. When just one present identifies a particular ISID to be
used for matching.
to higher-value — Identifies a range of ISIDs to be used as matching criteria.
inner-tag
Syntax inner-tag value [ vid-mask ]
no inner-tag
Context config>filter>mac-filter>entry>match
Description
This command configures the matching of the second tag that is carried transparently through the
service. The inner-tag on ingress is the second tag on the frame if there are no service delimiting tags.
Inner tag is the second tag before any service delimiting tags on egress but is dependent in the ingress
configuration and may be set to 0 even in cases where additional tags are on the frame. This allows
matching VLAN tags for explicit filtering or QoS setting when using default or null encapsulations.
The inner-tag is not applicable in ingress on dot1Q SAPs. The inner-tag may be populated on egress
depending on the ingress SAP type.
On QinQ SAPs of null and default that do not strip tags inner-tag will contain the second tag (which
is still the second tag carried transparently through the service.) On ingress SAPs that strip any tags,
inner-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 and vid-mask) = = (tag and vid-mask)). A value of 6 and
a mask of 7 would match all VIDs with the lower 3 bits set to 6.
Note for QoS the VID type cannot be specified on the default QoS policy.
The default vid-mask is set to 4095 for exact match.
