3. Configure the link type of ports
stp point-to-point { auto |
force-false | force-true }
Required.
By default, the port
automatically detects whether
its link is point-to-point.
If the current port is a Layer 2 aggregate interface or if it works in full duplex mode, you can configure
the link to which the current port connects as a point-to-point link. HP recommends that you use the
default setting, and let MSTP detect the link status automatically.
If a port is configured as connecting to a point-to-point link or a non-point-to-point link, the setting takes
effect for the port in all MSTIs.
If the physical link to which the port connects is not a point-to-point link and you manually set it to be one,
your configuration may cause temporary loops.
Configuring the mode a port uses to recognize/send MSTP
packets
A port can receive/send MSTP packets in the following formats:
• dot1s: 802.1s-compliant standard format, and
• legacy: Compatible format
By default, the packet format recognition mode of a port is auto. The port automatically distinguishes the
two MSTP packet formats, and determines the format of packets it will send based on the recognized
format.
Configure the MSTP packet format on a port. When working in MSTP mode after the configuration, the
port sends and receives only MSTP packets of the format you have configured to communicate with
devices that send packets of the same format.
Make this configuration on the root bridge and on the leaf nodes separately.
To configure the MSTP packet format to be supported on a port or a group of ports:
