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 6 on page 20.
■
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.
Enabling OAM Flush
You can use the atm oam flush command to enable the OAM flush feature for an
ATM interface. When OAM flush is enabled, the router ignores all OAM cells received
on the interface, and stops sending OAM cells on this interface.
You can also issue the atm oam flush command with the optional alarm-cells
keyword to cause the router to ignore only AIS and RDI cells and to accept all other
OAM cells. This is useful in diagnostic situations when you might want to exclude
alarm conditions.
NOTE: The OAM flush feature is supported on all E Series ATM module combinations.
