The remark policies are used to configure the marking behavior for the system at the egress of access SAPs, network port, hybrid ports, and access uplink ports. These policies allow the user to define the FC-to-egress marking values and allow them to use the available hardware resources efficiently. Based on the packet encapsulation used, the remark policy allows the user to define and associate service egress policies to access SAP egress and network QoS policies applied to network ports, hybrid ports, and access-uplink ports. The following type of remark policies are available:
dot1p
This policy is used for service egress and network QoS policies.
dscp
This policy is used for service egress and network QoS policies.
dot1p-dscp
This policy is used for service egress and network QoS policies.
lsp-exp
This policy is used for network QoS policies (only network ports and hybrid ports).
dot1p-lsp-exp
This policy is used for network QoS policies (only network ports and hybrid ports).
dot1p-lsp-exp-dscp
This policy is used for network QoS policies (only network ports and hybrid ports).
dscp-lsp-exp
This policy is used for network QoS policies (only network ports and hybrid ports).
The type of the remark policy identifies the bits marked in the packet header. Each of these remark policy types can be associated with only appropriate QoS policies and service entities, as listed in Table: Summary of remark policy and attachment points for 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C.
