Configuring The Mode A Port Uses To Recognize/Send Mstp Packets - HP A6600 Configuration Manual

To do...
3. Configure the link type of ports
A Layer 2 aggregate interface can be configured to connect to a point-to-point link. If a port works in
auto-negotiation mode and the negotiation result is full duplex, this port can be configured as connecting
to a point-to-point link.
If a port is configured as connecting to a 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 force it to be a
point-to-point link by configuration, the configuration may incur a temporary loop.
Configuring the mode a port uses to recognize/send MSTP
packets
A port can receive/send MSTP packets of two formats:
dot1s: 802.1s-compliant standard format, and
•
legacy: Compatible format
•
By default, the packet format recognition mode of a port is auto, namely the port automatically
distinguishes the two MSTP packet formats, and determines the format of packets it sends based on the
recognized format.
Configure the MSTP packet format on a port. After the configuration, when working in MSTP mode, 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.
Use the command...
stp point-to-point { auto |
force-false | force-true }

Remarks
Required.
auto by default, namely, the
port automatically detects
whether its link is point-to-point.
