in the range 1–4294967295, when you specify the rate of traffic flow with the CBR
service class. Because the CBR service category guarantees a fixed amount of
bandwidth to be allotted to the client, an error message is displayed if you configure
a value of 0 for the tunnel rate for CBR traffic flows.
If any virtual circuits are open within the VPI before the tunnel is created, the router
does not execute this command.
For more information about configuring a shapeless VP tunnel for QoS, see ATM
Integrated Scheduler Overview.
Example
host1(config-if)#atm vp-tunnel 2 128
Use the no version to remove the VP tunnel. When circuits are open within the tunnel,
the router does not remove the tunnel.
See atm vp-tunnel.
Use to scramble the ATM cell payload on a T3 or an E3 interface. DS3 (T3) and E3
scrambling assists clock recovery on the receiving end of the interface.
Example
host1(config-if)#ds3-scramble
Use the no version to disable scrambling.
See ds3-scramble.
See e3-scramble.
Use to set the time interval at which the router calculates bit and packet rate counters
for the ATM interface.
You can choose a multiple of 30 seconds, in the range 30–300 seconds.
Example
host1(config-if)#load-interval 90
Use the no version to return to the default setting, 300 seconds.
See load-interval.
Use to place the interface into loopback mode.
Specify either:
diagnostic—Places the interface into internal loopback.
line —Places the interface into external loopback.
