Configure The Connect-Sequence Interface-Recovery Option - HP 7102dl - ProCurve Secure Router Configuration Manual

Configuring Backup WAN Connections
Configuring Demand Routing for Backup Connections
Replace <value> with the number of times the ProCurve Secure Router will
cycle through the connect sequences specified for a demand interface. You
can specify a number between 0 and 65535. The default setting is 1.
Specifying 0 places no limit on the number of attempts.

Configure the connect-sequence interface-recovery Option

When the ProCurve Secure Router tries to establish a connection, one of the
following conditions will result:
A Dial-Up Interface Is Available, and the Call Is Connected. If the
ProCurve Secure Router successfully establishes a physical connection
(Layer 1), it will begin to negotiate a PPP session with the far-end router.
No Dial-Up Interfaces Are Available. Backup interfaces on the ProCurve
Secure Router are not directly bound to a specific primary connection. You
could use a dial-up interface to provide backup for multiple connections. If
no dial-up interface in the associated resource pool is available for use when
the demand interface determines that it must initiate a backup connection,
the ProCurve Secure Router places all interfaces in the resource pool in fast-
idle mode. This mode decreases the amount of time an interface can remain
idle before the router disconnects the ISDN connection. The router then
monitors the dial-up interfaces until one becomes available. When an interface
becomes available, the ProCurve Secure Router uses that interface to dial a
connect sequence. At the same time, the router cancels the fast-idle mode for
the resource pool. (For more information about fast-idle mode, see "Config-
uring the fast-idle Option" on page 3-36.)
A Dial-Up Interface Is Available, But the Call Fails. If a dial-up inter-
face is available and the ProCurve Secure Router attempts to establish a
connection, the call may fail for a number of reasons: a busy signal, no answer,
connection timeout, and so on. When a connection attempt fails, the router
increments the failure count for that connect sequence and then tries to use
the next connect sequence to establish a dial-up connection.
The busyout-threshold option determines the number of times the ProCurve
Secure Router processes a particular connect sequence during each connect
sequence attempt.
For example, if connect sequence 10 has a busyout-threshold of 3 and connect
sequence 11 has a busyout-threshold of 2, the router will process connect
sequence 10 three times and connect sequence 11 twice (alternating between
the two sequences). If, at the end of the five total attempts, the router cannot
establish a connection, it has made one connect sequence attempt.
