ATM Switch Router Software Configuration Guide
OL-7396-01
Chapter 11 Configuring ATM Routing and PNNI
Basic PNNI Configuration
To change the active ATM address you must create a new address, verify that it exists, and then delete
the current active address. After you have entered the new ATM address, disable node 1 and then
reenable it. At the same time, you can change the node level if required for your configuration. The
identifiers for all higher level nodes are recalculated based on the new ATM address.
Caution Node IDs and peer group IDs are not recalculated until the node is disabled and then reenabled.
To change the active ATM address, perform these steps, beginning in global configuration mode:
Example
The following example changes the ATM address of the switch from the autoconfigured address
47.0091.8100.0000.0041.0b0a.1081.0041.0b0a.1081.00 to the new address prefix
47.0091.8100.5670.0000.0000.1122.0041.0b0a.1081.00,
and causes the node identifier and peer group
identifier to be recalculated:
Switch(config)# atm address 47.0091.8100.5670.0000.0000.1122...
Switch(config)# no atm address 47.0091.8100.0000.0041.0b0a.1081...
Switch(config)# atm router pnni
Switch(config-atm-router)# node 1 disable
Switch(config-pnni-node)# node 1 enable
Command Purpose
Step 1
Switch(config)# atm address new-address-template Configures the new ATM address for the switch.
Step 2
Switch(config)# end
Switch#
Returns to privileged EXEC mode.
Step 3
Switch# show atm addresses Verifies the new address.
Step 4
Switch# configure terminal
Switch(config)#
Enters configuration mode from the terminal.
Step 5
Switch(config)# no atm address
old-address-template
Removes the old ATM address from the switch.
Step 6
Switch(config)# atm router pnni
Switch(config-atm-router)#
Enters ATM router PNNI mode from the
terminal.
Step 7
Switch(config-atm-router)# node 1 disable
Switch(config-pnni-node)#
Disables the PNNI node.
Step 8
Switch(config-pnni-node)# node 1 level number
enable
Reenables the node. You can also change the
node level if required for your configuration.
