Description

separate values.
af11 ... be
One or more DSCP values specified according to the Assured
Forwarding group, as defined in RFC 2597 and RFC 3260. See the
table below for values. “ef” means expedited forwarding (DSCP
46) and “be” means best effort (DSCP 0). Voice traffic is typically
given a value of ef.
cs0 ... cs7
One or more DSCP values specified according to the Class
Selector group. This is equivalent to TOS IP precedence values, so
that CS0 is equivalent to an IP precedence value of 0, CS1 is
equivalent to an IP precedence value of 1, and so on.
