Step Description Command Keys
3 Set the match between DSCP codes
values of incoming packets and
outgoing queues.
The given match works for incoming
interfaces/tunnels/bridge on which QoS
is enabled (optional).
esr(config)# qos map dscp-queue
<DSCP> to <QUEUE>
<DSCP> – service classifier in a
packet IP header, takes values
in the range of [0..63];
<QUEUE> – queue identifier,
takes values in the range of
[1..8].
Default values:
DSCP: (0-7), queue 1
DSCP: (8-15), queue 2
DSCP: (16-23), queue 3
DSCP: (24-31), queue 4
DSCP: (32-39), queue 5
DSCP: (40-47), queue 6
DSCP: (48-55), queue 7
DSCP: (56-63), queue 8
4 Set the match between 802.1p codes
values of incoming packets and
outgoing queues.
The given match works for incoming
interfaces/tunnels/bridge on which QoS
is enabled (optional).
esr(config)# qos map cos-queue
<COS> to <QUEUE>
<COS> – service classifier in
802.1q packet tag, takes values
in the range of [0..7];
<QUEUE> – queue identifier,
takes values in the range of
[1..8].
Default values:
CoS: (0), queue 1
CoS: (1), queue 2
CoS: (2), queue 3
CoS: (3), queue 4
CoS: (4), queue 5
CoS: (5), queue 6
CoS: (6), queue 7
CoS: (7), queue 8
5 Set the match between DSCP codes
values of incoming packets and
outgoing DSCP codes (if remarking is
required).
The given match works for incoming
interfaces/tunnels/bridge on which QoS
is enabled.
esr(config)# qos map dscp-queue
<DSCP> to <DSCP>
<DSCP> – service classifier in a
packet IP header, takes values
in the range of [0..63].
6 Enable DSCP codes changes according
to the DSCP-Mutation table (if
remarking is required).
esr(config)# qos dscp mutation
7 Set the number of the default queue to
which all traffic except IP falls into the
trust mode for DSCP priorities.
esr(config)# qos queue default
<QUEUE>
<QUEUE> – queue identifier,
takes values in the range of
[1..8].
