Sample Display
A simple configuration of a VBR-nrt PVC is provided in the following text. Note that per subinterface
configuration display is supported since 12.0T.
Medina#
sh run interface atm 3/0.1
Building configuration...
Current configuration:
!
interface ATM3/0.1 multipoint
no ip directed-broadcast
map-group MyMap
atm pvc 4 0 36 aal5snap 2000 1000 32
end
This assumes that we have a map list definition matching the map group name, as shown in this partial
configuration:
<snip>
!
map-list MyMap
ip 10.2.1.1 atm-vc 4 broadcast
ip 10.2.1.2 atm-vc 4 broadcast
<snip>
We can check the mapping with the same command as for the new syntax:
Medina
#sh atm map
Map list MyMap : PERMANENT
ip 10.2.1.1 maps to VC 4
, broadcast
ip 10.2.1.2 maps to VC 4
, broadcast
Again, you will see that the new syntax is easier and clearer.
Before Calling Cisco Systems TAC Team
Before calling Cisco Systems's Technical Assistance Center (TAC), make sure that you have read
through this chapter and completed the actions suggested for your system's problem.
Additionally, do the following and document the results so that we can better assist you:
Do a
show tech
of both routers, to help the CSE in understanding the router behavior.
•
Do a
sh atm pvc
on both routers and a
sh atm pvc
vpi/vci
of the PVC that gives problem, to help
the CSE in understanding the problem.
•
Explain the ATM provider point-of-view on the problem, especially if the provider believes that the
problem is on the router.
