Managing Link Failover Protection

Link failover provides an easily configurable means of raising a backup link upon the failure of a designated main
link. The main and backup links can be Ethernet, Cellular Modem, T1/E1, or DDS.
Link failover can back up to multiple remote locations, managing multiple main-to-backup link relationships. When
the backup link is a modem, many profiles of dialed numbers can exist, each serving as a distinct backup link.
Link failover can back up a permanent, high-speed WAN link to a permanent, low-speed WAN link. Use this
function when OSPF cannot be employed, such as on public links.
Link failover can also be used to migrate the default route from the main link to the backup link.
The time after a main link failure to backup link startup, and the time after a main link recovery to backup link
stoppage, are configurable. The link failover function also provides failover status information and a test of the
failover settings.
The following sections describe how to configure link failover protection:
• Section 5.27.1, "Viewing the Link Failover Log"
• Section 5.27.2, "Viewing the Link Failover Status"
