Table 30 Advanced Application > Spanning Tree Protocol > Status: MSTP (continued)
LABEL | DESCRIPTION |
Forwarding Delay | This is the time (in seconds) the root switch will wait before changing states (that |
(second) | 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 | This field displays the configuration name for this MST region. |
Name |
|
|
|
Revision Number | This field displays the revision number for this MST region. |
|
|
Configuration | A configuration digest is generated from the |
Digest | This field displays the |
| field displays the digest when MSTP is activated on the system. |
|
|
Topology | This is the number of times the spanning tree has been reconfigured. |
Changed Times |

|
Time Since Last | 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 |

|
|
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 |
