Dial Backup Commands
The following set of commands defines a backup dial line.
backup
This command set backup functionality on Serial, Ethernet or sub‐interfaces. You can also specify
a delay before a secondary interface is brought up or down after a primary interface is brought up
or down. We suggest this command be used when lines suffer intermittent disruptions causing
the primary line to come up and fall temporarily. A backup delay ensures the secondary line does
not come up and down prematurely.
Syntax
backup interface dialer dialer-interface-number [delay enable-delay disable-delay
[never]][time-range hh:mm hh:mm]
Syntax of the “no” Form
The no form of this command removes backup from the interface:
no backup interface
Default
1 second
Mode
Interface configuration: XSR(config-if<xx>)#
Example
The following example provides a 10‐second delay in activating the secondary line and a 20‐
second delay in deactivating the secondary line when the primary serial line goes up and down.
XSR(config)#interface serial 1/1
XSR(config-if<S1/1>)#backup delay 10 20
XSR(config-if<S1/1>)#no shutdown
Note: The XSR sets UTC for time-range calculation.
interface Dialer interface number used for backup.
delay
enable-delay
disable-delay Backup enable delay, ranging from 0 to 99999999, followed by the backup disable
delay, ranging frm 0 to 99999999, or the keyword never indicating the backup,
once enabled, is not being disabled when the primary link comes up.
The enable-delay is the interval in seconds that elapses after the primary port goes
down. The disable-delay is the interval in seconds that elapses after the primary port
comes up.
never Stops the secondary port from being deactivated.
time-range
hh:mm hh:mm Backup timer range - start from hh:mm to end hh:mm. When backup is not set, it is
is always active. Otherwise it is active during the configured time range only.
