7.4.1.2 Application Requirements
As shown above, users from respective departments of the enterprise access
network through Switch A and Switch B. Due to network interruption caused by
link failure or such non-device factors as the contrived network loop, RLDP loop
detection and unidirectional/bidirectional link detection must be configured to
instantly locate and handle faults, so that the network can be recovered instantly
and the losses caused by network failure can be reduced. Major needs include:
z The loop error or unidirectional/bidirectional link failure detected can be
handled as per the fault-handling method configured.
z If the port configured with "shutdown-port" fault-handling is failed, the
RLDP detection can be recovered and all failed ports can start detection
again.
