DESCRIPTION
This is the time (in seconds) the root switch will wait before changing states (that
is, listening to learning to forwarding).
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.
This field displays the configuration name for this MST region.
This field displays the revision number for this MST region.
A configuration digest is generated from the VLAN-MSTI mapping information.
This field displays the 16-octet signature that is included in an MSTP BPDU. This
field displays the digest when MSTP is activated on the system.
This is the number of times the spanning tree has been reconfigured.
This is the time since the spanning tree was last reconfigured.
These fields display the MSTI to VLAN mapping. In other words, which VLANs run
on each spanning tree instance.
This field displays the MSTI ID.
This field displays which VLANs are mapped to an MSTI.
Select the MST instance settings you want to view.
Root refers to the base of the MST instance. Our Bridge is this Switch. This
Switch may also be the root bridge.
This is the unique identifier for this bridge, consisting of bridge priority plus MAC
address. This ID is the same for Root and Our Bridge if the Switch is the root
switch.
This is the path cost from the root port in this MST instance to the regional 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 MST instance.
