Setting a Loopback Location ID

atm oam loopback-location
34
aal5autoconfig
The oam keyword is not available with the aal5all, aal0, or ilmi
Optionally, you can configure the time interval in the range 1–600 seconds between
transmissions of OAM F5 end-to-end loopback cells.
Use the following keywords to enable and configure CC cell flows:
end-to-end—Opens an end-to-end CC cell flow
segment—Opens a segment CC cell flow
sink—Enables this VC as a sink point (cell receiver)
source—Enables this VC as the source point (cell generator)
both—Enables this VC as both a sink point and a source point
Example 1—Enables F5 end-to-end loopback cells
host1(config-if)#atm pvc 20 20 20 aal5snap oam
Example 2—Enables end-to-end CC cell flow and enables the PVC as the sink
host1(config-if)#atm pvc 5 0 5 aal5autoconfig oam cc end-to-end sink
Use the no version of the atm pvc command without the oam keyword to disable F5
OAM on the PVC and without the cc keyword to disable CC cell flows on the PVC. For
example, the following command disables CC cell flow configured in Example 2.
host1(config-if)#no atm pvc 5 0 5 aal5autoconfig
See atm pvc.
To enable other nodes to specifically send OAM loopback cells to the ATM interface, set
the location ID of the ATM interface or circuit.
host1(config-if)#atm oam loopback-location 01090708
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.
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).
