SPANNING - TREE MST PORT - PRIORITY
29-23
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• Each spanning-tree instance is associated with a unique set of VLAN
IDs.
• This command is used by the multiple spanning-tree algorithm to
determine the best path between devices. Therefore, lower values
should be assigned to interfaces attached to faster media, and higher
values assigned to interfaces with slower media.
•Use the no spanning-tree mst cost command to specify
auto-configuration mode.
• Path cost takes precedence over interface priority.
Example
Related Commands
