Setting a Physical Port to Mask DiffServ Bits
Command
Use the set port mask-diffserv command to mask the three least
significant bits of the DSCP when the switch is using the DSCP to
classify bridged IP traffic. If you mask the three least significant bits
of the DSCP, the switch recognizes the remaining bits as the
precedence field of the type of service (TOS) field and classifies the
packets accordingly.
The syntax of this command is:
Avaya(configure)#set port mask-diffserv {{<mod-num> | <mod-
swport-range>} [..., {<mod-num> | <mod-swport-range>}] | all-
ports} {on | off}
Table 6-147. Keywords, Arguments, and Options
Keyword, Argument
or Option Definition
<mod-num> The slot number of a module. If you
specify <mod-num>, all ports on the
module mask the three least significant
bits of the DSCP.
<mod-swport-range> The slot number of a module, and, either
a port number, or a range of port
numbers having the format Px-Py. For
example:
• To specify port 1 on the module in
slot 3, enter 3/1.
• To specify ports 1 through 5 on the
module in slot 3, enter 3/1-5.
If you specify <mod-swport-range>, the
port or range of ports on the module that
you specify mask the three least
significant bits of the DSCP.
{all-ports} All ports in the chassis. If you enter all-
ports, all ports in the chassis are set to
mask the three least significant bits of the
DSCP.
