34 Backup Services
Introduction
Backup Services are intended to be an integral part of a well-designed Wide Area Network
(WAN). The purpose of a backup service is to provide an alternate route for data to take in
the event of failure of the Primary port or Virtual Circuit. Initially, the primary entity may be
either a physical port (any physical port type in the system), or a frame relay Private Virtual
Circuit (PVC). The backup is via an ISDN BRI running Point-to-Point Protocol (PPP).
Backup services are configured by specifying information on the primary entity, the backup
entity, and timers that control under what conditions the system will switch to backup mode.
Both the primary and backupentities must be configured prior to accessing this menu. This
menu also does no cross-checking to ensure that the primary being backed up is backed up
by an “appropriate” backup entity. This is the responsibility of the user.
