Root Bridge Configuration 129
Configuration procedure (in system view)
Configuration procedure (in Ethernet port view)
Among aggregated ports, you can only configure the links of master ports as
point-to-point links.
If an autonegotiating port operates in full duplex mode after negotiation, you can
configure the link of the port as a point-to-point link.
After you configure the link of a port as a point-to-point link, the configuration
applies to all spanning tree instances. If the actual physical link of a port is not a
point-to-point link and you forcibly configure the link as a point-to-point link,
temporary loops may be incurred.
Configuration example
1 Configure the link connected to GigabitEthernet1/0/1 port as a point-to-point link.
■ Configure in system view.
