defined in the SAP egress policy associated with each SAP is used to mark the packets egressing
out of SAP if marking is enabled. In port-based marking, the remark policy defined in the access-
egress policy associated with the access port determines the marking values to use for all the SAPs
defined on that port. SAP-based marking is only supported for L2 SAPs, that is, SAPs configured
in Epipe, VPLS and PBB (I-SAPs only) service. Port-based marking is supported for both L3
SAPs, that is, SAPs configured in VPRN services, PBB B-SAPs and other L2 SAPs. More
information on the CLI command 'sap-qos-marking' is available in the 7210 Systems guide. The
access egress policy is used only when port-based marking has been enabled (that is, sap-qos-
marking is set to disable).
The system uses the access egress policy for marking only if the port with which this policy is
associated is enabled for port-based marking (that is, the command sap-qos-marking is set to
disable). When port-based marking is enabled, the system is capable of marking all the packets
egressing out of the port with either dot1p or dscp or both (that is, both dot1p and dscp). If
remarking is enabled and the remark policy is of type 'dot1p' or 'dot1p-lsp-exp-shared' then the
dot1p bits are marked in the packet based on the FC to dot1p values specified in the remark policy.
If remarking is enabled and the remark policy is of type 'dscp' then the IP DSCP bits are marked
in the packet. If remarking is enabled and the remark policy is of type 'dot1p-dscp' then both
dot1p and IP DSCP bits are marked in the packet.
Note: When port-based marking is enabled and marking for both dot1p and IP DSCP bits is
configured, the system marks dot1p and IP DSCP bits for all the packets sent out of both L2 SAPs
and L3 SAPs. It is recommended that if both L2 and L3 SAPs are configured on the same port,
then remark policy of type dot1p, that marks only dot1p bits be used.
The no form of this command deletes the access-egress policy. A policy cannot be deleted until it
is removed from all access ports where it is applied. When an access-egress policy is removed
from an access port, the access port will revert to the default access-egress policy-id 1.
policy-id — The value that uniquely identifies the access-egress policy.
Parameters
