Interface Configuration (Ethernet, Port Channel)

Command Usage

■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.

Example

Console(config)#interface ethernet SNP5

Console(config-if)#spanning-tree link-type point-to-point

Console(config-if)#
