Configuring WAN Line Services
2-22 117021-A Rev. A
Enable or disable remote loopback detection for the interface.
Setting the Hold Down Time
On a synchronous interface configured for dial services, you can specify a time
period (0 to 9999 seconds) for the router to wait before bringing down a backup
line. This delay allows time for the primary line to fully recover before
deactivating the backup line.
For a dial-on-demand interface, the Sync Hold Down Time parameter is set to 3
seconds by default.
The Sync Hold Down Time parameter is set to 0 by default. Set the hold down
time to a value from 0 to 9999 seconds for the interface.
Setting a Priority
On a synchronous interface configured for dial or switched services, you can
assign a priority number (from 1 to 50) to each line within the same demand or
backup pool.
The lower the number, the higher the Sync Priority. For example, the router uses a
line of priority 1 before it uses a line of priority 2.
Set the priority for the interface.
