PA-A2 ATM CES Configurations
To configure the ESI and Selector fields, you must also configure a PVC to communicate with the switch
through ILMI:
Router(config-if)# pvc 0/16 ilmi
The switch then provides the Prefix field of the NSAP address.
Configuring the Complete NSAP Address Manually
When you configure the NSAP address manually, you must enter the entire address in hexadecimal
format; that is, each digit entered represents a hexadecimal digit. To represent the complete NSAP
address, you must enter 40 hexadecimal digits in the following format:
XX.XXXX.XX.XXXXXX.XXXX.XXXX.XXXX.XXXX.XXXX.XXXX.XX
Note
All NSAP addresses must be entered in the dotted hexadecimal format shown, which conforms to the
UNI specification.
Because the interface has no default NSAP address, you must configure the NSAP address for SVCs. To
set the ATM interface source NSAP address, enter the following command in interface configuration
mode:
nsap-address nsap-address
The following is an example of an NSAP address assigned to ATM interface 4/0 on a Cisco 7200 series,
Cisco uBR7200 series, or Cisco 7100 series router:
Router (config)# interface atm 4/0
Router (config-if)# nsap-address AB.CDEF.01.234567.890A.BCDE.F012.3456.7890.1234.12
You can display the ATM address for the interface by executing the show interfaces atm command.
Configuring the ESI and Selector Fields
You can configure the router to get the NSAP address prefix from the switch; however, the switch must
be capable of delivering the NSAP address prefix to the router through ILMI, and the router must be
configured with a PVC for communication with the switch through ILMI.
To configure the router to get the NSAP prefix from the switch and use locally entered values for the
remaining fields of the address, complete the following tasks in interface configuration mode:
Specify an ATM interface to configure.
Step 1
Router(config)# interface atm slot/port or slot/port-adapter/port
Step 2
Enter the ESI and Selector fields of the NSAP address.
Router(config-if)# esi-address esi.selector
In the esi-address command, the esi argument is 6 hexadecimal bytes long (12 digits), and the selector
argument is 1 hexadecimal byte long (2 digits).
