Configuring Port Priority; Configuring The Link Type Of Ports - HP A6600 Configuration Manual

Configuring port priority

The priority of a port is an important factor in determining whether the port can be elected as the root port
of a device. If all other conditions are the same, the port with the highest priority is elected as the root
port.
On an MSTP-enabled device, a port can have different priorities in different MSTIs, and the same port
can play different roles in different MSTIs, so that data of different VLANs can be propagated along
different physical paths, thus implementing per-VLAN load balancing. Set port priority values based on
the actual networking requirements.
Make this configuration on the leaf nodes only.
To configure the priority of a port or a group of ports:
To do...
1. Enter system view
2. Enter
interface
view or port
group view
3. Configure the port priority
When the priority of a port is changed, MSTP re-calculates the role of the port and initiate a state
transition.
Generally, a lower priority value indicates a higher priority. If you configure the same priority value for
all ports on a device, the specific priority of a port depends on the index number of the port. A lower
index number means a higher priority. Changing the priority of a port triggers a new spanning tree
calculation process.

Configuring the link type of ports

A point-to-point link is a link directly connecting two devices. If the two ports across a point-to-point link
are root ports or designated ports, the ports can rapidly transition to the forwarding state after a
proposal-agreement handshake process.
Make this configuration on the root bridge and on the leaf nodes separately.
To configure the link type of a port or a group of ports:
