Chapter 34 switch Commands
34.6.8.3 switch dscp set Command
Syntax:
switch dscp set <giga-port> <srccp> <mapcp> <mappri>
where
<srccp>
<mapcp>
<mappri>
This command configures DSCP to DSCP mapping and DSCP to IEEE 802.1p mapping on a
Gigabit Ethernet interface. You can change the DSCP of received (IEEE 802.1p tagged)
packets to a different DSCP. You can also map it to a specific IEEE 802.1p priority.
The following example sets subtending 1 Gigabit Ethernet interface to map packets with a
source DSCP of 7 to a DSCP of 5 and a IEEE 802.1p priority of 1.
ras> switch dscp set sub1 7 5 1
34.6.8.4 switch dscp show Command
Syntax:
switch dscp show [<giga-port>]
This command displays the DSCP to DSCP mapping and DSCP to IEEE 802.1p mapping
settings on a Gigabit Ethernet interface.
The following example displays the subtending 1 Gigabit Ethernet interface's DSCP to DSCP
mapping and DSCP to IEEE 802.1p mapping settings.
ras> switch dscp show sub1
dscp mapping(codepoint/priority): disabled

60 60/7 61/7 62/7 63/7
The top row and first column identify the source DSCP. The other rows identify the DSCP to
which the source DSCP is mapped followed by the IEEE 802.1p priority to which it is
mapped. The bolded section in this example shows that packets received with a DSCP of 7 get
their code point changed to 5 and are given an IEEE 802.1p priority of 1.

Specify a source DiffServ Code Point (DSCP) or points, 0~63. For example:
1,3~5,10~15
Specify the DSCP (0~63) to which you want to map the source DSCP (or
DSCPs).
Specify the IEEE 802.1p priority (0~7) to which you would like to map the
source DSCP (or DSCPs).
