DESCRIPTION
This is the priority and number of the port on the switch through which this
switch must communicate with the root of the Spanning Tree. "0x0000" displays
when this device is the root switch.
This is the maximum time (in seconds) the root switch can wait without receiving
a configuration message before attempting to reconfigure.
This is the time interval (in seconds) at which the root switch transmits a
configuration message. The root bridge determines Hello Time, Max Age and
Forwarding Delay.
This is the time (in seconds) the root switch will wait before changing states
(that is, listening to learning to forwarding).
This is the maximum time (in seconds) the IES-612-51A can wait without
receiving a configuration message before attempting to reconfigure.
This is the time interval (in seconds) at which the IES-612-51A transmits a
configuration message. The root bridge determines Hello Time, Max Age and
Forwarding Delay.
This is the time (in seconds) the IES-612-51A will wait before changing states
(that is, listening to learning to forwarding).
This identifies the IES-612-51A's ports that support the use of STP. If STP is
activated, the following fields appear. If STP is not activated, Disabled appears.
This field displays the port's RSTP (or STP) state. With RSTP, the state can be
discarding, learning or forwarding. With STP, the state can be disabled,
blocking, listening, learning, or forwarding.
Disabled appears when RSTP has not been turned on for the individual port or
the whole device.
This is the priority and number of the port on the switch through which this
switch must communicate with the root of the Spanning Tree. "0x0000" displays
when this device is the root switch.
This is the path cost from this port to the root switch.
This is the path cost from the root port on this switch to the root switch.
This is the unique identifier for the bridge that has the lowest path cost to reach
the root bridge, consisting of bridge priority plus MAC address.
This is the port on the designated bridge that has the lowest path cost to reach
the root bridge, consisting of bridge priority.
The text box displays how often (in seconds) this screen refreshes. You may
change the refresh interval by typing a new number in the text box and then
clicking Set Interval.
Click Stop to halt STP statistic polling.
