Description
Set the IPv4 Differentiated Services code point
(DSCP) bit. You can specify a numerical value from 0 through 63. To specify the value in hexadecimal form, include 0x as a prefix. To specify the value in binary form, include b as a prefix.
The default DSCP value is be (best effort), or 0.
For M320 and T Series routers, set the DSCP field
of incoming or outgoing packets to 000000. On the same
packets, you can use a behavior aggregate (BA) classifier and a rewrite
rule to rewrite the MPLS EXP field.
For MX Series routers with MPCs and EX Series switches, the DSCP field can be set from a numeric range.
For MX Series routers and EX Series switches, if you configure
a firewall filter with a dscp action or traffic-class action on a DPC, the commit fails.
If you apply a firewall filter with a dscp action on an
AE member interface, the commit fails. However, you can apply a firewall filter with
a dscp action on a full AE interface.
