Table 51
Advanced Application > Spanning Tree Protocol > Status: MSTP
LABEL
DESCRIPTION
Configuration
Click
Configuration
to specify which STP mode you want to activate. Click
MSTP
to edit
MSTP settings on the Switch.
CST
This section describes the Common Spanning Tree settings.
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) the 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.
