Setting a Loopback Location ID

To enable other nodes to specifically send OAM loopback cells to the ATM interface, set the location ID of the ATM interface or circuit.

Note: Because the router is a connection endpoint, the default loopback location ID is all 1s (ones). This command enables you to specify a nondefault value.

atm oam loopback-location

• Use to set the location ID of the ATM interface. The location ID is a 4-octet field, and the default value is all 1s (ones).
  • You can set a specific value to identify this ATM interface as the intended recipient of OAM loopback cells.
  • You can also set the location ID to all 0s (zeros).

  For information about how the router handles loopback cells based on location ID, see Table 7.

• Example

  host1(config-if)#atm oam loopback-location 01090708

• Use the no version to return the loopback location ID to the default value, all 1s (ones).
• See atm oam loopback-location.
