OAM Settings

By default, an activated ATM interface sends F5 Operation, Administration,
and Maintenance (OAM) cells over a reserved VCI to monitor the ATM link
and ensure that is open from end-to-end. The oam retry command enables
you to configure the OAM settings that the ProCurve Secure Router OS uses
to determine if a PVC is up or down.
Syntax: oam retry <up-count> <down-count> <retry-frequency>
The <up-count> option determines the number of consecutive, end-to-end
F5 OAM loopback cell responses that the ADSL interface must receive before
the Secure Router OS changes a PVC connection state to up.
Replace <up-count> with a number between 1 and 255. The default setting is 3.
The <down-count> option determines the number of consecutive, end-to-end
F5 OAM loopback cell responses that the ATM subinterface must miss before
the Secure Router OS changes the PVC state to down.
Replace <down-count> with a number between 1 and 255. The default
setting is 5.
The <retry-frequency> option determines the frequency (in seconds) at
which the ADSL interface transmits F5 OAM loopback cells when verifying a
PVC state change. Replace <retry-frequency> with a number of seconds
between 1 and 600. The default setting is 1 second.
The value you specify for the <retry-frequency> option is used only when
the Secure Router OS is verifying a change in the state of a PVC. To configure
the time delay between OAM loopback cells for all other circumstances, you
enter this command from the ATM subinterface configuration mode context:
Syntax: oam-pvc managed <frequency>
This command determines the number of seconds the Secure Router OS waits
between transmitting OAM loopback cells. The range is 0 to 600 seconds, and
the default setting is 1 second.
For example, to configure the Secure Router OS to wait 4 seconds between
transmitting OAM loopback cells, enter:
ProCurve(config-atm 1.1)# oam-pvc managed 4
7-27
