Using Hunt Groups to Aggregate Bandwidth between
Switches
Hunt groups allow you to aggregate multiple switch ports into a single group, effectively
combining the bandwidth into a single connection.
For example, if you connect three gigabit ports each on a pair of switches into a hunt
group, the aggregated connection will have six gigabits of available bandwidth (full-
duplex).
Path Cost
Sets the spanning tree path cost for this port. The ports that you
prefer be used by the spanning tree should have the lowest path
cost.
Note: Configuring the path cost for a link when the link is in
the down state is not saved in the configuration NV memory.
Establish the link first, before configuring the path cost.
Top. Change
Detection
Allows you to enable or disable topology change detection.
Specifies whether a Topology Change Notification (TCN) packet
is sent through the root port (or if this switch is the root bridge,
whether or not Fast Aging occurs) whenever the port enters the
forwarding or blocking states. This attribute should only be used
on port which connect to no other switches.
Note: A topology change occurs when you change a port
mirroring piggyback port.
