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.
Syntax:
set {cmg_card-addr} priority tos {disable|mask-value
match-value}
Example:
set 5 priority tos oxfc oxb8.
{cmg_card-addr}
The slot number (1-6) that contains the CMG Router card.
{disable|mask-value match-value}
The following table contains the appropriate TOS mask and match for various IP precedence
and DiffServ code points:
disable Disable (default), will result in no priority handling of routed voice
packets
mask-value Mask to be applied to the TOS byte in the IP header. In the format of
0x (2 hex digits)
match-value TOS byte match value. In the format of 0x (2 hex digits).
