Configuring ATM Routing and PNNI
Advanced PNNI Configuration
Displaying the Administrative Weight Per Interface Configuration
To display the ATM PNNI interface AW configuration, use the following EXEC command:
Example
The following example shows the AW configuration for interface 0/0/0 using the show atm pnni 
interface
 EXEC command:
Switch# show atm pnni interface atm 0/0/0 detail
Port ATM0/0/0 is up  , Hello state 2way_in with node eng_18 
    Next hello occurs in 11 seconds, Dead timer fires in 73 seconds

Configuring Transit Restriction
Transit calls originate from another ATM switch and pass through the switch. Some edge switches might 
want to eliminate this transit traffic and only allow traffic originating or terminating at the switch.
To configure a transit restriction, perform these steps, beginning in global configuration mode:
Example
The following example shows how to enable the transit-restricted feature:
Switch(config)# atm router pnni
Switch(config-atm-router)# node 1
Switch(config-pnni-node)# transit-restricted
Displaying the Transit Restriction Configuration
To display the ATM PNNI transit-restriction configuration, use the following privileged EXEC 
command:
Command
Purpose
show atm pnni [interface atm 
card/subcard/port] [detail]
Displays the interface ATM PNNI AW 
configuration.
Command
Purpose
Step 1
Switch(config)# atm router pnni
Switch(config-atm-router)# 
Enters ATM router PNNI mode.
Step 2
Switch(config-atm-router)# node node-index
Switch(config-pnni-node)# 
Enters node configuration mode.
Step 3
Switch(config-pnni-node)# transit-restricted
Enables transit restricted on this node.
