CIST Ports & Aggregations State
Port The switch port number of the logical STP port.
Port ID The port id as used by the STP protocol. This is
the priority part and the logical port index of the
bridge port.
Role The current STP port role. The port role can be
one of the following values: AlternatePort
BackupPort RootPort DesignatedPort.
State The current STP port state. The port state can
be one of the following values: Discarding
Learning Forwarding.
Path Cost The current STP port path cost. This will either
be a value computed from the Auto setting, or
any explicitly configured value.
Edge The current STP port (operational) Edge Flag.
An Edge Port is a switch port to which no
Bridges are attached. The flag may be
automatically computed or explicitly configured.
Each Edge Port transits directly to the
Forwarding Port State, since there is no
possibility of it participating in a loop.
Point2Point The current STP port point-to-point flag. A
point-to-point port connects to a non-shared
LAN media. The flag may be automatically
computed or explicitly configured. The
point-to-point properties of a port affect how fast
it can transit to STP state.
Uptime The time since the bridge port was last
initialized.
