You can change the DSCP -> internal forwarding mappings. You also can change the internal forwarding priority
-> hardware forwarding queue mappings.
Changing the DSCP –> Internal Forwarding Priority Mappings
To change the DSCP –> internal forwarding priority mappings for all the DSCP ranges, enter commands such as
the following at the global CONFIG level of the CLI:
FESX424 Router(config)# qos-tos map dscp-priority 0 2 3 4 to 1
FESX424 Router(config)# qos-tos map dscp-priority 8 to 5
FESX424 Router(config)# qos-tos map dscp-priority 16 to 4
FESX424 Router(config)# qos-tos map dscp-priority 24 to 2
FESX424 Router(config)# qos-tos map dscp-priority 32 to 0
FESX424 Router(config)# qos-tos map dscp-priority 40 to 7
FESX424 Router(config)# qos-tos map dscp-priority 48 to 3
FESX424 Router(config)# qos-tos map dscp-priority 56 to 6
FESX424 Router(config)# ip rebind-acl all
These commands configure the mappings displayed in the DSCP to forwarding priority portion of the QoS
information display. To read this part of the display, select the first part of the DSCP value from the d1 column and
select the second part of the DSCP value from the d2 row. For example, to read the DSCP to forwarding priority
mapping for DSCP value 24, select 2 from the d1 column and select 4 from the d2 row. The mappings that are
changed by the command above are shown below in bold type.
FESX424 Router(config-if-e1000-1)# show qos-tos
...portions of table omitted for simplicity...
DSCP-Priority map: (dscp = d1d2)
d2| 0 1 2 3 4 5 6 7 8 9
d1 |
-----+----------------------------------------
0 | 1 0 1 1 1 0 0 0 5 1
1 | 6 1 1 1 1 1 4 2 2 2
2 | 2 2 2 2 2 3 3 3 3 3
3 | 3 3 0 4 4 4 4 4 4 4
4 | 7 5 5 5 5 5 5 5 3 6
5 | 6 6 6 6 6 6 6 7 7 7
6 | 7 7 7 7
Syntax: [no] qos-tos map dscp-priority <dscp-value> [<dscp-value> ...] to <priority>
The <dscp-value> [<dscp-value> ...] parameter specifies the DSCP value ranges you are remapping. You can
specify up to seven DSCP values in the same command, to map to the same forwarding priority. The first
command in the example above maps priority 1 to DSCP values 0, 2, 3, and 4.
The <priority> parameter specifies the internal forwarding priority.
Changing the Internal Forwarding Priority –> Hardware Forwarding Queue Map-
pings
To reassign an internal forwarding priority to a different hardware forwarding queue, enter commands such as the
following at the global CONFIG level of the CLI:
FESX424 Router(config)# qos tagged-priority 2 qosp0
Syntax: [no] qos tagged-priority <num> <queue>
The <num> parameter can be from 0 – 7 and specifies the internal forwarding priority.
