Dscp Re-Marking Configuration Example 1; Dscp Re-Marking Configuration Example 2 - Lenovo ThinkSystem NE2552E Application Manual

DSCP Re-Marking Configuration Example 1
1. Turn DSCP re‐marking on globally, and define the DSCP‐DSCP‐802.1p mapping.
2. Enable DSCP re‐marking on a port.
DSCP Re-Marking Configuration Example 2
1. Create an ACL to re‐mark DSCP value and COS queue for all VoIP packets.
2. Create an ACL to set a low priority to all other traffic.
3. Apply the ACLs to a port and enable DSCP marking.
4. Enable DSCP re‐marking globally.
5. Assign the DSCP re‐mark value.

NE2552E Application Guide for ENOS 8.4
The following example includes the basic steps for re‐marking DSCP value and
mapping DSCP value to 802.1p.
You can use the default mapping.
NE2552E(config)# qos dscp re-marking
NE2552E(config)# qos dscp dscp-mapping <DSCP value (0‐63)> <new value>
NE2552E(config)# qos dscp dot1p-mapping <DSCP value (0‐63)> <802.1p value>
NE2552E(config)# interface port 1
NE2552E(config-if)# qos dscp re-marking
NE2552E(config-if)# exit
The following example assigns strict priority to VoIP traffic and a lower priority to
all other traffic.
NE2552E(config)# access-control list 2 tcp-udp source-port 5060 0xffff
NE2552E(config)# access-control list 2 meter committed-rate 10000000
NE2552E(config)# access-control list 2 meter enable
NE2552E(config)# access-control list 2 re-mark in-profile dscp 56
NE2552E(config)# access-control list 2 re-mark dot1p 7
NE2552E(config)# access-control list 2 action permit
NE2552E(config)# access-control list 3 action set-priority 1
NE2552E(config)# access-control list 3 action permit
NE2552E(config)# interface port 5
