Usage Guidelines
Specify a point-to-point link if the interface can only be connected to exactly one other bridge, or a shared
link if it can be connected to two or more bridges.
When automatic detection is selected, the switch derives the link type from the duplex mode. A full-duplex
interface is considered a point-to-point link, while a half-duplex interface is assumed to be on a shared link.
RSTP only works on point-to-point links between two bridges. If you designate a port as a shared link, RSTP
is forbidden. Since MSTP is an extension of RSTP, this same restriction applies.
Example
The following is sample output from the spanning-tree link-type command.
Console(config)#interface ethernet ethernet 1/5
Console(config-if)#spanning-tree link-type point-to-point
16.217 spanning-tree mst cost
This command configures the path cost on a spanning instance in the Multiple Spanning Tree. Use the no
form to restore the default.
Syntax Description
spanning-tree mst instance_id cost cost
no spanning-tree mst instance_id cost
instance_id Instance identifier of the spanning tree. (Range: 1-4094, no leading zeroes)
cost Path cost for an interface. (Range: 1-200,000,000) The recommended range is:
• Ethernet: 200,000-20,000,000
• Fast Ethernet: 20,000-2,000,000
• Gigabit Ethernet: 2,000-200,000
