Chapter 26  MSTP Commands 
MSTP (Multiple Spanning Tree Protocol), compatible with both STP and RSTP and subject to 
IEEE 802.1s, can disbranch a ring network. STP is to block redundant links and backup links as 
well as optimize paths. 
spanning-tree global 
Description 
The  spanning-tree global command is used to configure STP globally. To 
return to the default configuration, please use no spanning-tree global 
command. 
Syntax 
spanning-tree global 
[status { disable | enable }] [mode { stp | rstp | mstp }] 
[cist cist] [htime hello-time] [mage max-age] [delay forward-delay] [hcount 
hold-count
] [mhop max-hops
no spanning-tree global 
Parameter 
status  ——  Enable/ Disable STP function globally. By default, it is disabled. 
mode  —— STP Version. There are three options, including STP (Spanning 
Tree Protocol), RSTP (Rapid Spanning Tree Protocol) and MSTP (Multiple 
Spanning Tree Protocol). By default, the STP version is STP. 
cist
  ——  CIST Priority, which must be multiple of 4096 ranging from 0 to 61440. 
By default, the CIST priority is 32768. CIST Priority is an important criterion on 
determining the root bridge. In the same condition, the switch with the highest 
priority will be chosen as the root bridge. The lower value has the higher priority. 
hello-time
  —— Hello Time, which is the interval to send BPDU packets, and 
used to test the links. Hello Time ranges from 1 to10 in seconds and it is 2 by 
default. Otherwise, 2 * (Hello Time + 1) <= Max Age. 
max-age
  ——  Max Age, which is the maximum time the switch can wait without 
receiving a BPDU before attempting to reconfigure. Max Age ranges from 6 to 
40 in seconds. By default, it is 20. 
forward-delay
  —— Forward Delay, which is the time for the port to transit its 
state after the network topology is changed. Forward Delay ranges from 4 to 30 
in seconds and it is 15 by default. Otherwise, 2 * (Forward Delay - 1) >= Max 
Age.
