criterion).The available egress CAM hardware resources can be allocated as per user
needs for use with different filter criteria using the commands under configure>
system>resource-profile> egress-internal-tcam> acl-sap-egress. By default, the system
allocates resources to maintain backward compatibility with release 4.0. Users can modify
the resource allocation based on their needs to scale the number of entries or the number of
associations (that is, number of SAP/IP interfaces using a filter policy that defines a
particular match criterion).
IPv6 ACLs and MAC QoS policies cannot co-exist on the SAP.
If no CAM resources are allocated to a particular match criterion defined in a filter policy,
then the association of that filter policy to a SAP will fail. This is true for both ingress and
egress filter policy.
IPv6 ACLs and MAC QoS policies cannot co-exist on the SAP.
For traffic ingressing a B-VPLS SAP and destined to a B-VPLS SAP, the MAC filter
matches the B-domain, MAC header fileds (that is, B-DA, B-SA, and others). The MAC
filter can be used to match customer payload MAC header fields for traffic ingressing a B-
VPLS SAP and destined to an I-VPLS SAP.
If a MAC filter policy is created with an entry and entry action specified but the packet
matching criteria is not defined, then all packets processed through this filter policy entry
will pass and take the action specified. There are no default parameters defined for
matching criteria.
MAC filters cannot be applied to network interfaces, routable VPLS or IES services.
Some of the MAC match criteria fields are exclusive to each other, based on the type of
Ethernet frame. Use the following table to determine the exclusivity of fields.In the 7210
SAS, the default frame-format is "EthernetII"
