Configuring F5 Oam - Juniper JUNOSE SOFTWARE 11.0.X - LINK LAYER CONFIGURATION GUIDE 4-1-2010 Configuration Manual

Configuring F5 OAM

F5 OAM flows run over existing PVCs. The ATM interface does not support sending
F5 segment loopback cells, but it does respond to F5 segment loopback cells that it
receives.
NOTE: You cannot enable both loopback cells and CC cells at the same time.
To set up F5 OAM:
1.
2.
When you issue the appropriate shutdown command to change the administrative
status of the corresponding ATM interface, ATM AAL5 interface, or ATM 1483
subinterface from enabled to disabled, the router automatically disables all F5 OAM
services configured on the associated VC. For more information, see "Automatic
Disabling of F5 OAM Services" on page 20.

Use the no version to delete F4 OAM circuits. Using the options, you can delete
all F4 OAM circuits on the interface, segment or end-to-end F4 OAM circuits, or
F4 OAM circuits on a specific VPI.
Example 1 Deletes all F4 OAM circuits on the interface
host1(config-if)#no atm oam
Example 2 Deletes all F4 segment OAM circuits on the interface
host1(config-if)#no atm oam segment
Example 3 Deletes the F4 end-to-end OAM circuit on VPI 8
host1(config-if)#no atm oam 8 end-loopback
See atm oam.
To enable VC integrity, which causes the ATM interface to periodically send F5
end-to-end loopback cells over a VC, use the oam keyword with the atm pvc
command.
You can include the frequency (in seconds) with which the router sends F5
end-to-end loopback cells.
host1(config-if)#atm pvc 98 38 22 aal5snap oam 300
(Optional) To enable CC cell flows on a circuit, use the cc keyword with the
atm pvc command. You can enable cell flows on a segment or end-to-end basis,
and you can enable the PVC as a sink, source, or both a sink and a source.
host1(config-if)#atm pvc 50 0 50 aal5snap oam cc end-to-end sink
