INTRODUCTION TO CLI
<prio: 0-61440>: Specify a priority value.
Explanation:
Specify an appropriate priority for a MSTI instance. Bridge priority is used in selecting the root device,
root port, and designated port. The device with the highest priority becomes the root device. However, if all devices
have the same priority, the device with the lowest MAC address will then become the root device. Note that lower
numeric values indicate higher priority. The bridge priority plus the MSTI instance number, concatenated with the 6-
byte MAC address of the switch forms a Bridge Identifier.
Example:
Map MST Instance 1 to priority 61440.
Negation:
(config)# no spanning-tree mst <instance> priority
Show:
# show spanning-tree
3.9.45.15 (config)# spanning-tree mst <instance> vlan <v_vlan_list>
Syntax:
(config)# spanning-tree mst <instance> vlan <v_vlan_list>
Parameters:
<instance: 0-7>: Specify an instance ID. “0” means CIST. “1-7” means MSTI 1-7.
<v_vlan_list>: Specify a list of VLANs for the specified MST instance. Separate VLANs with a comma and use
hyphen to denote a range of VLANs. (Example: 2,5,20-40)
Explanation:
Specify VLANs mapped to a certain MSTI. Both a single VLAN and a range of VLANs are allowed.
Example:
Map MST Instance 1 to VLAN 90 and VLAN 101-105.
Negation:
(config)# no spanning-tree mst <instance> vlan
3.9.45.16 (config)# spanning-tree mst forward-time
Syntax:
(config)# spanning-tree mst forward-time <fwdtime>
Parameters:
<fwdtime: 4-30>: Specify forward delay value between 4 and 30 (seconds).
Explanation:
Fort STP bridges, the Forward Delay is the time spent in each Listening and Learning state before the
Forwarding state is entered. This delay occurs when a new bridge comes onto a network.
Example:
Set the forward delay to 15 seconds.
# config t
(config)# spanning-tree mst 1 vlan 90,101-105
# config t
(config)# spanning-tree mst 1 priority 61440
