root bridge/secondary root
bridge
Configure the bridge priority
of the current switch
Configure the mode a port
recognizes and sends MSTP
packets
Configure the MSTP
operation mode
Configure the maximum hop
count of an MST region
Configure the network
diameter of the switched
network
Configure the MSTP
time-related parameters
Configure the timeout time
factor
Configure the maximum
transmitting speed of the port
Configure the current port as
an edge port
Specify whether the link
connected to a port is a
point-to-point link
In a network containing switches with both GVRP and MSTP enabled, GVRP
packets are forwarded along the CIST. If you want to advertise packets of a specific
VLAN through GVRP, be sure to map the VLAN to the CIST when configuring the
MSTP VLAN mapping table (the CIST of a network is spanning tree instance 0).
The role (root, branch, or leaf) of each switch in each spanning tree instance is
determined.
Description
