The remark policies configure the marking behavior for the system at the egress of access SAP or access uplink port. These policies allow the user to define the FC-to-egress marking values and 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 service egress and network QoS policies to access-uplink port. The following remark policies are available:
dot1p
This policy is used for service egress policy, and network QoS.
dscp
This policy is used for service egress and network QoS.
dot1p-dscp
This policy is used for service egress and network QoS.
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 the following table.
Remark policy type |
QoS policy |
Attachment point |
Packet header bits marked |
|---|---|---|---|
dot1p |
Service egress policy |
Access SAP egress |
dot1p bits and optionally the DEI bits, in the L2 header for service packets sent out of an Access SAP |
Network policy |
Access-uplink port |
dot1p bits and optionally the DEI bits, in the L2 header for service packets sent out of an access-uplink port (all packets sent out of all access-uplink SAPs are marked) |
|
dscp |
Service egress policy |
Access SAP egress |
IP DSCP bits in the IP header (if present) for service packets sent out of an Access SAP |
Network policy |
Access-uplink port |
IP DSCP bits in the IP header (if present) 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 |
|
dot1p-dscp |
Service egress policy |
Access SAP egress |
dot1p bits and optionally the DEI bits, in the L2 header for service packets sent out of access SAP. 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 SAP |
Network policy |
Access-uplink port |
dot1p bits and optionally the DEI bits, in the L2 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 |
