Set (Router) Priority Tos - Black Box Compact T1 MT850A User Manual

CLI Commands
set

set (router) priority tos

Use the set (router) priority tos command to configure parameters that will be used to
recognize routed voice packets which will be handled with higher priority over other routed
data.
For each IP datagram to be routed, the TOS byte from the IP header will be logically AND'd
with the configured TOS mask and compared to the TOS match value. If they match, the
datagram will be handled with a greater priority than other routed data but with lower priority
than its own VoIP data. This command takes effect immediately.

{cmg_card-addr}
