ARAMETERS
These parameters are displayed:
STA Bridges
◆
MSTI – The Bridge Instance. This is also a link to the STP Detailed
Bridge Status.
◆
Bridge ID – A unique identifier for this bridge, consisting of the bridge
priority, and MAC address (where the address is taken from the switch
system).
◆
Root ID – The priority and MAC address of the device in the Spanning
Tree that this switch has been accepted as the root device.
◆
Root Port – The number of the port on this switch that is closest to the
root. This switch communicates with the root device through this port.
If there is no root port, then this switch has been accepted as the root
device of the Spanning Tree network.
◆
Root Cost – The path cost from the root port on this switch to the root
device. For the root bridge this is zero. For all other bridges, it is the
sum of the port path costs on the least cost path to the root bridge.
