LABEL

DESCRIPTION

CST

This section describes the Common Spanning Tree settings.

Bridge

Root

Bridge

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

Bridge

and

Our Bridge

if the Switch is the root switch.

Hello Time
(seconds)

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

Max Age
(seconds)

This is the maximum time (in seconds) the Switch can wait without receiving a configuration
message before attempting to reconfigure.

Forwarding Delay
(seconds)

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.

Regional 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

Regional 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.

Port

This field displays the number of the port on the Switch.
