oam-pvc
To enable end-to-end F5 Operation, Administration, and Maintenance (OAM) loopback cell generation
and OAM management for an ATM permanent virtual circuit (PVC), virtual circuit (VC) class, or
label-controlled ATM (LC-ATM) VC, use the oam-pvc command in the appropriate command mode. To
disable generation of OAM loopback cells and OAM management, use the no form of this command.

Syntax Description manage (Optional for ATM VCs or VC classes; required for LC-ATM VCs) Enables OAM
m
anagement. The default is disabled.
frequency (Optional) Specifies the time delay between transmitting OAM loopback cells, in
s
econds. For ATM VCs or VC classes and loopback mode detection, the range is
from 0 to 600, and the default is 10. For LC-ATM VCs, the range is from 0 to 255,
and the default is 5.
loop-detection Enables automatic detection of whether the physically connected ATM switch is in
l
oopback mode. The default is disabled.
auto-detect (Optional) Enables auto-detection of peer OAM command cells.
optimum (Optional) Configures an optimum mode so that when the traffic-monitoring timer
e
xpires, the PVC sends an OAM command cell at the locally configured frequency
instead of going into Retry mode immediately. If there is no response, the PVC
goes into Retry mode.
keep-vc-up (Optional) Specifies that the VC will be kept in the UP state when continuity check
(
CC) cells detect connectivity failure.
seg aisrdi
f
ailure
(Optional) Specifies that if segment alarm indication signal/remote defect indication
(AIS/RDI) cells are received, the VC will not be brought down because of end CC
failure or loopback failure.
