Tracking

4.1 Interface tracking

With interface tracking the Switch monitors the link status of:
physical ports
link aggregation interfaces (interfaces 8.x)
VLAN router interfaces (interfaces 9.x)
Ports/interfaces can have the following link statuses:
interrupted physical link (link down) and
existing physical link (link up).
A link aggregation interface has link status "down" if the link to all the partic-
ipating ports is interrupted.
A VLAN router interface has link status "down" if the link is interrupted from
all the physical ports/link aggregation interfaces that are members of the cor-
responding VLAN.
Setting a delay time enables you to insert a delay before informing the appli-
cation about an object state change.
An interface object is given the "down" status if the physical link interruption
remains for longer than the "link down delay" delay time.
An interface object is given the "up" status if the physical link holds for longer
than the "link up delay" delay time.
On delivery, the delay times are set to 0 seconds. This means that if a status
changes, the registered application is informed immediately.
You can define an interface tracking object for each interface.
