Enabling OAM Flush

Copyright © 2010, Juniper Networks, Inc.
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).
For information about how the router handles loopback cells based on location ID, see
Table 6 on page 19.
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.
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.
