Parameter
group-number: Number of the detect group, in the range 1 to 100.
Description
Use the standby detect-group command to implement interface backup using the
auto detect function.
Use the undo standby detect-group command to disable interface backup using the
auto detect function.
Using the result of auto detect, you can control whether to enable the backup interface.
When a detect group is referenced for interface backup, the router does one of the
following:
z When the detect group is reachable, use the main interface.
z When the detect group is unreachable, enable the backup interface.
z When the unreachable detect group becomes reachable again, switch over to the
main interface.
This command is configured on the backup interface.
Example
# Enable backup up interface Serial 0/0/0 when detect group 10 is unreachable.
<3com> system-view
System View: return to User View with Ctrl+Z.
