CIST Ports
This page allows the user to inspect the current STP CIST port configurations, and possibly
change them as well.This page contains settings for physical and aggregated ports. The
aggregation settings are stack global.
Label
Description
Port
The switch port number of the logical STP port.
STP Enabled
Controls whether STP is enabled on this switch port.
Path Cost
Controls the path cost incurred by the port. The Auto setting will
set the path cost as appropriate by the physical link speed, using
the 802.1D recommended values. Using the Specific setting, a
user-defined value can be entered. The path cost is used when
establishing the active topology of the network. Lower path cost
ports are chosen as forwarding ports in favor of higher path cost
ports. Valid values are in the range 1 to 200000000.
Priority
Controls the port priority. This can be used to control priority of
ports having identical port cost. (See above).
OpenEdge(setate
flag)
Operational flag describing whether the port is connecting directly
to edge devices. (No Bridges attached). Transitioning to the
forwarding state is faster for edge ports (having operEdge true)
than for other ports.
AdminEdge
Controls whether the operEdge flag should start as beeing set or
cleared. (The initial operEdge state when a port is initialized).
AutoEdge
Controls whether the bridge should enable automatic edge
detection on the bridge port. This allows operEdge to be derived
from whether BPDU's are received on the port or not.
