4.2.2.1 Default TTL
When packets are generated by the FCM9002 manager, they will be transmitted
with the value configured here. It is unlikely that the default value of 32 will need
to be changed, though it may be set in the range 1 to 255 bearing in mind that
the TTL value is decremented by 1 for each router on the route.
4.2.2.2 DSCP Priority
When packets are transmitted by the FCM9002 manager, they will be transmitted
with the configured DSCP ( Differentiated Services Code Point ) value. DSCP
may be specified in the range 0 to 63 with 0 being best effort.
The exact meaning and priority of DSCP values are network dependant , though
the following table usually applies for traffic classification.
