Configuring STA for Ports or Modules

The following figure and table describe STA configuration for ports or modules. (Note that the Spanning Tree Configuration screen for the expansion slots also indicates module type.)

Figure 2-24. Spanning Tree Port Configuration

Parameter	Default	Description
Fast forwarding mode	ENABLED	Allows you to enable or disable fast forwarding for
of all ports		all ports on the switch.
Type		Shows 10/100TX, 100FX, 1000LX or 1000SX port.
Priority	128	Defines the priority for the use of a port in the STA
		algorithm. If the path cost for all ports on a switch
		are the same, the port with the highest priority (i.e.,
		lowest value) will be configured as an active link in
		the spanning tree. Where more than one port is
		assigned the highest priority, the port with lowest
		numeric identifier will be enabled.
		The range is 0 - 255.
(Path) Cost	100/19/4	This parameter is used by the STA algorithm to
		determine the best path between devices.
		Therefore, lower values should be assigned to
		ports attached to faster media, and higher values
		assigned to ports with slower media.
		(Path cost takes precedence over port priority.)
		The default and recommended range is:
		Ethernet: 100 (50~600)
		Fast Ethernet: 19 (10~60)
		Gigabit Ethernet: 4 (3~10)
		The full range is 1 - 65535.
