Port number shown in the row. Only ports
running BPDU exchanging over the network are
shown at this table;
Port ID, that is, the port identifier number, in the
format “Port
-Priority.Bridge-Port-
Number”;
Role on the port, that is, Spanning Tree port
state. Roles can be RootPort, DesignatedPort,
AlternatePort and BackupPort;
State of the port, which can be forwarding or
discarding;
Port’s Path Cost, which is the path cost used by
that port when transmitting BPDU packets over
the network;
Edge, that is, if port is an edge port or not.
Allowed values are Yes or No. Yes means port is
an edge port, and No means port is a trunk port
(not edge);
Point-to-Point, that is, if port communication is
point-to-point or a shared link medium;
Uptime, which represents time since port is up.
o
Bridge ID, that is, the bridge identifier number, in the format
“Priority.Bridge
-MAC-
Address”;
o
Root ID, that is, the root bridge identifier number, in the format
“Priority.Bridge
-MAC-
Address”;
o
Root port, that is, the port at the bridge operating as Root Port;
o
Root path cost;
o
Topology Flag, that is, current value of the change flag at this
instance;
o
Topology Change Last, which represents last time since topology
has changed at the selected instance.
Port Status:
STP Port Status monitoring option allows user to view basic information about all
ports at the switch related to Spanning Tree information in Reason Switches.
Information allowed is as follows:
o
Port number shown in the row;
o
CIST Role on the port, that is, Spanning Tree port state. Roles can
be RootPort, DesignatedPort, AlternatePort, BackupPort and
Disabled;
o
CIST State of the port, which can be forwarding or discarding;
o
Uptime, which represents time since port is up.
