DESCRIPTION
Click Configuration to specify which STP mode you want to activate.
Click MSTP to edit MSTP settings on the Switch.
This section describes the Common Spanning Tree settings.
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.
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 time interval (in seconds) at which the root switch transmits
a configuration message.
This is the maximum time (in seconds) the Switch can wait without
receiving a configuration message before attempting to reconfigure.
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.
