Chapter2 Basic NSP Configuration
ATM Address
Note The first 13 bytes of the address make up a switch prefix used by ILMI in assigning addresses to end
stations connected to User-Network Interface (UNI) ports.
• MAC address of the NSP—6 bytes (used to distinguish multiple end system identifier [ESI]
addresses)
Note Both MAC address fields in the ATM address are the same, but they will not be the same as the address
printed on the chassis label.
• Selector equals 0—1 byte
Configuring the ATM Address Manually
Manually configuring the ATM address is required:
• To connect to another system using Interim Interswitch Signaling Protocol (IISP). Using IISP
requires disabling PNNI, which results in no ILMI support.
• To configure a new ATM address that replaces the previous ATM address and generates a new PNNI
node ID and peer group ID for migrating from flat to hierarchical PNNI.
• To connect to multiple levels of a PNNI hierarchy.
• To connect to a service provider network that requires you to use the addressing scheme for that
network.
• To use a particular style of addressing. For instance, in some circumstances a mnemonic scheme
might be useful for identifying nodes in an ATM network.
To configure a new ATM address, refer to the chapter “Configuring ATM and PNNI” in the ATM Switch
Router Software Configuration Guide.
Caution ATM addressing can lead to conflicts if not configured correctly. If you are configuring a new ATM
address, the old one must be completely removed from the configuration.
Example
The following example shows how to change the active ATM address, create a new address, verify that
it exists, and then delete the current active address. Using the ellipses (...) adds the default Media Access
Control (MAC) address as the last six bytes.
Switch(config)# atm address 47.0091.8100.5670.0000.0ca7.ce01...
Switch(config)# end
Switch# show atm addresses
