Summary (Is-Is View) - 3Com S7906E Command Reference Manual

The overload bit is not set by default.
Note that:
If the on-startup keyword is not specified, the command sets the overload bit immediately until the
undo set-overload command is executed.
If the on-startup keyword is specified, IS-IS sets the overload bit upon system startup and keeps it
set within the timeout2 interval.
If both on-startup and start-from-nbr system-id are specified, IS-IS sets the overload bit from
system startup to when the neighbor relationship with the specified neighbor is formed within the
nbr-timeout interval, and from then on, IS-IS keeps the overload bit set within the timeout1 interval.
If the neighbor relationship with the specified neighbor is not formed within the nbr-timeout interval,
the overload bit is cleared.
Examples
# Set overload flag on the current router.
