Root port ID
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.
Root max age
(second)
This is the maximum time (in seconds) the root switch can wait without receiving
a configuration message before attempting to reconfigure.
Root hello time
(second)
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
.
Root forward delay
(second)
This is the time (in seconds) the root switch will wait before changing states
(that is, listening to learning to forwarding).
Max age (second)
This is the maximum time (in seconds) the IES-1248 can wait without receiving
a configuration message before attempting to reconfigure.
Hello time (second)
This is the time interval (in seconds) at which the IES-1248 transmits a
configuration message. The root bridge determines

and
Forwarding Delay
.
Forward delay
(second)
This is the time (in seconds) the IES-1248 will wait before changing states (that
is, listening to learning to forwarding).
Port Status
This identifies the IES-1248’s ports that support the use of STP.
State
This field displays the port’s RSTP (or STP) state. With RSTP, the state can be

, or
forwarding
.
Disabled
appears when RSTP has not been turned on for the individual port or
the whole device.
Port ID
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.
Path cost
This is the path cost from this port to the root switch.
Cost to root
This is the path cost from the root port on this switch to the root switch.
Designated bridge
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.
Designated port
This is the port on the designated bridge that has the lowest path cost to reach
the root bridge, consisting of bridge priority.
