NOTE: You cannot enable both loopback cells and CC cells at the same time.
To set up F5 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
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 19.
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
