SSE-G2252/SSE-G2252P Switches User's Manual
Default Setting
By default, the system automatically detects the speed and duplex mode used on each
port, and configures the path cost according to the values shown below. Path cost "0" is
used to indicate auto-configuration mode. When the short path cost method is selected
and the default path cost recommended by the IEEE 8021w standard exceeds 65,535,
the default is set to 65,535. The default path costs are listed in
Path Costs" on page
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
SSE-G2252(config)#interface Ethernet 1/5
SSE-G2252(config-if)#spanning-tree mst 1 cost 50
SSE-G2252(config-if)#
