Bridge
Root refers to the base of the spanning tree (the root bridge). Our
Bridge is this Switch. This Switch may also be the root bridge.
Bridge ID
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.
Hello Time
(second)
This is the time interval (in seconds) at which the root switch transmits
a configuration message.
Max Age
(second)
This is the maximum time (in seconds) a switch can wait without
receiving a configuration message before attempting to reconfigure.
Forwarding
Delay (second)
This is the time (in seconds) the root switch will wait before changing
states (that is, listening to learning to forwarding).
Cost to Bridge
This is the path cost from the root port on this Switch to the root
switch.
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.
Configuration
Name
This field displays the configuration name for this MST region.
Revision
Number
This field displays the revision number for this MST region.
Configuration
Digest
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.
Topology
Changed Times
This is the number of times the spanning tree has been reconfigured.
Time Since Last
Change
This is the time since the spanning tree was last reconfigured.
Instance:
These fields display the MSTI to VLAN mapping. In other words, which
VLANs run on each spanning tree instance.
Instance
This field displays the MSTI ID.
VLAN
This field displays which VLANs are mapped to an MSTI.
MSTI
Select the MST instance settings you want to view.
Bridge
Root refers to the base of the MST instance. Our Bridge is this Switch.
This Switch may also be the root bridge.
Bridge ID
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.
Internal Cost
This is the path cost from the root port in this MST instance to the
regional root switch.
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 MST instance.
