The priority <value> parameter specifies the preference that 802.1W gives to this port relative to other ports for
forwarding traffic out of the topology. You can specify a value from 8 – 252, in increments of 4. If you enter a value
that is not divisible by four the software rounds to the nearest value that is. The default is 128. A higher numerical
value means a lower priority; thus, the highest priority is 8
Set the admin-edge-port to enabled or disabled. If set to enabled, then the port becomes an edge port in the
domain.
Set the admin-pt2pt-mac to enabled or disabled. If set to enabled, then a port is connected to another port
through a point-to-point link. The point-to-point link increases the speed of convergence. This parameter,
however, does not auto-detect whether or not the link is a physical point-to-point link.
The force-migration-check parameter forces the specified port to sent one RST BPDU. If only STP BPDUs are
received in response to the sent RST BPDU, then the port will go return to sending STP BPDUs.
USING THE WEB MANAGEMENT INTERFACE
You cannot modify 802.1W port parameters using the Web management interface.
EXAMPLE:
Suppose you want to enable 802.1W on a system with no active port-based VLANs and change the hello-time
from the default value of 2 to 8 seconds. Additionally, suppose you want to change the path and priority costs for
port 5 only. To do so, enter the following commands.
HP9300(config)# spanning-tree 802-1w hello-time 8
HP9300(config)# spanning-tree 802-1w ethernet 5 path-cost 15 priority 64
