Dscp Re-Marking Configuration Example 1; Dscp Re-Marking Configuration Example 2 - Lenovo CN4093 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.

CN4093 Application Guide for N/OS 8.3
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.
CN 4093(config)# qos dscp re-marking
CN 4093(config)# qos dscp dscp-mapping <DSCP value (0-63)> <new value>
CN 4093(config)# qos dscp dot1p-mapping <DSCP value (0-63)> <802.1p value>
CN 4093(config)# interface port 1
CN 4093(config-if)# qos dscp re-marking
CN 4093(config-if)# exit
The following example assigns strict priority to VoIP traffic and a lower priority to
all other traffic.
CN 4093(config)# access-control list 2 tcp-udp source-port 5060 0xffff
CN 4093(config)# access-control list 2 meter committed-rate 10000000
CN 4093(config)# access-control list 2 meter enable
CN 4093(config)# access-control list 2 re-mark in-profile dscp 56
CN 4093(config)# access-control list 2 re-mark dot1p 7
CN 4093(config)# access-control list 2 action permit
CN 4093(config)# access-control list 3 action set-priority 1
CN 4093(config)# access-control list 3 action permit
CN 4093(config)# interface port 5
