35.14.8.4 switch port mstp p2plink Command
Syntax:
switch port mstp p2plink <giga-port> auto|enable|disable
where
Enable a point-to-point link between Gigabit Ethernet interfaces to increase the speed of
convergence by allowing the network to determine the designated port faster. The port must be
connected directly to another switch port.
The following example activates point-to-point link on uplink port 2.
35.14.8.5 switch port mstp pathcost Command
Syntax:
switch port mstp pathcost <giga-port> <mstid> <cost>
This command sets the path cost of the specified Gigabit Ethernet interface in the spanning tree.
The path cost can be between 0 and 200000000. A smaller number means a lower path cost. For
paths with the same priority, the switch will select the one on lower interface number first. 0 sets
the system automatically determines the path cost based on the line speed.
The following example sets the path cost of uplink interface 1 to 200 in spanning tree 10.
35.14.8.6 switch port mstp priority Command
Syntax:
switch port mstp priority <giga-port> |all <mstid> <priority>
This command sets the priority (between 0 and 255 in multiples of 16) of the Gigabit Ethernet
interface in the specified spanning tree. When a loop occurs and two root ports have the same cost,
the port with higher priority (lower numerical value) becomes the root port and the other port
becomes an alternate port. For ports with the same priority, the switch will select the one on lower
interface number first.
The following example sets the port priority of uplink interface 1 to 16 in spanning tree 10.
auto =
The switch automatically determines if the link is point-to-point based on the port’s
duplex mode setting.
enable =
Activates this feature on a full-duplex port that is connected directly to another
switch port.
disable =
Deactivates this feature on the port that is in half-duplex mode.
