Items Description
CIST Aggregation Port Configuration
STP Enable Control whether STP is enabled on this
switch port
Path Cost Control the Path Cost incurred by this
port. The
“Auto” setting will set the path
cost as approciate by physical link speed,
using the 802.1D recommended values.
Using
“specific” settings, a user-defined
value can be entered. The path cost is
used when establishing the active
topology of the network. Low path cost
ports are chosen as forwarding ports in
favour of higher path cost ports.
(Range

1-200000000)
Priority Control the port priority. This can be used
to control priority of the ports having
identical port cost.
Admin Edge Enable this option if this port is connected
to an end node or at the end o the bridge.
Auto Edge Control whether automatic edge detection
is enabled on a bridge port
Restricted Role If enabled, cause the port not to be
selected as Root port for the CIST, even if

vector. This features is also known as
