1.6.8 Example for Associating Interface Backup with NQA to
Configure an ISDN Interface as the Backup of an Ethernet Interface
This section provides an example showing how to associate interface backup with NQA.
Networking Requirements
As shown in
connects to the IP network through GE1/0/0. The link between GE1/0/0 and the IP network is
used as the primary link, and the link between PRI1/0/0:15 (ISDN interface) and the ISDN is
used as the backup link. To prevent service interruption due to faults on the primary link,
associate interface backup with NQA on RouterA. When the NQA test instance detects faults
on the primary link, it reports faults to the interface backup module. The interface backup module
then switches traffic to the backup link of PRI1/0/0:15.
