Setting A Loopback Location Id - Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010 Configuration Manual

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.

Configuring OAM
Use the atm pvc command with the oam keyword to set up the PVC to
periodically transmit F5 end-to-end loopback cells over a VC.
You can use the oam keyword only if you specify one of the following
encapsulation types:
aal5snap
aal5mux ip
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.
host1(config-if)#atm oam loopback-location 01090708
