Overview of remark policies for 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

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:

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.

Remark policy type

QoS policy

Attachment point

Packet header bits marked

dot1p

Service egress policy

Access SAP egress (applicable to SAPs configured on access ports or hybrid ports)

dot1p bits, and optionally the DEI bits, in the outermost Ethernet header for service packets sent out of an Access SAP

Network policy

Network port

hybrid port

dot1p bits, and optionally the DEI bits, in the outermost Ethernet header for all MPLS and IP packets sent out of a network IP interface configured on a network port or hybrid port

Network policy

Access-uplink port

dot1p bits, and optionally the DEI bits, in the Ethernet header for service packets sent out of an access-uplink port (all packets sent out of all access-uplink SAPs are marked)

dscp

Access-uplink port

dot1p bits, and optionally the DEI bits, in the Ethernet header for service packets sent out of access uplink port. In addition to the dot1p bits, the IP DSCP bits in the IP header (if present) are marked for service packets sent out of an access-uplink port. Marking is done for packets sent out of all the access-uplink SAPs configured on the access-uplink port
