down stability timer
The up and down stability timers are the delay times that the primary link must be above the
threshold before the secondary is activated or below threshold before it is brought down.
This prevents activation or deactivation of the secondary link due to momentary peaks or
drops in traffic.
Bandwidth Allocation Control Protocol (BACP) may be used to negotiate the link activation
between partner routers (BACP must be used if the partner router is not another router).

Call mode determines which router originates the call to bring up the second link.
If BACP is not used, the partner routers will use proprietary negotiations to determine
which router is to activate the second link.
