STA attributes for interfaces when the spanning tree
mode is set to STP or RSTP. You may use a different
priority or path cost for ports of the same media type to
indicate a preferred path or Edge Port to indicate if the
attached device can support fast forwarding or link type
to indicate a point-to-point connection or shared-media
connection.
MST ID:
Select the MST ID from the list.
Port:
Portortrunkedportidentier.
Priority:
Denesthepriorityusedforthis
port in the Spanning Tree Algorithm.
If the path cost for all ports on a
Switch are the same, the port with
the highest priority (i.e., lowest
value)willbeconguredasanactive
link in the Spanning Tree. This makes
a port with higher priority less likely
to be blocked if the Spanning Tree
Algorithm is detecting network
loops. When more than one port is
assigned the highest priority, the
portwithlowestnumericidentier
will be enabled. The range is from
0-240, in steps of 16; and the
defaultis:128.
Internal Path Cost Conf:
The Internal Path Cost setting
allows you to specify the relative
costofsendingspanningtreetrafc
throughtheinterfacetoadjacent
bridges within a spanning tree
region.
Internal Path Cost Oper:
The External Path Cost setting is
used to calculate the cost of sending
spanningtreetrafcthroughthe
interfacetoreachanadjacent
spanning tree region. The spanning
tree algorithm tries to minimize the
total path cost between each point
of the tree and the root bridge.
