DESCRIPTION
Click STP Config to modify the IES-1248-51's STP settings (see
on page 169).
This field displays On if STP is activated. Otherwise, it displays Off.
This is the unique identifier for this bridge, consisting of bridge priority plus MAC
address. This ID is the same in Designated root ID if the IES-1248-51 is the
root switch.
This is the unique identifier for the root bridge, consisting of bridge priority plus
MAC address. This ID is the same in Our bridge ID if the IES-1248-51 is the
root switch.
This is the number of times the spanning tree has been reconfigured.
This is the time since the spanning tree was last reconfigured.
This is the path cost from the root port on this switch to the root switch.
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-1248-51 can wait without
receiving a configuration message before attempting to reconfigure.
This is the time interval (in seconds) at which the IES-1248-51 transmits a
configuration message. The root bridge determines Hello Time, Max Age and
Forwarding Delay.
This is the time (in seconds) the IES-1248-51 will wait before changing states
(that is, listening to learning to forwarding).
This identifies the IES-1248-51's ports that support the use of STP.
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.
