The switch software can be set to use the IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) or the IEEE 802.1s Multiple Spanning Tree Protocol (MSTP). If RSTP/MSTP is turned on, you can view the following RSTP bridge information for the Spanning Tree Group:

•Current root MAC address

•Path-Cost

•Port

•Hello interval

•Maximum age value

•Forwarding delay

•Aging time

You can also refer to the following port-specific RSTP information:

•Port number and priority

•Cost

•State

•Role•Designated bridge and port•Link typeThe following table describes the STP parameters in RSTP or MSTP mode.Table 26 Rapid Spanning Tree parameter descriptions

Parameter	Description
Current Root	Shows information about the root bridge for the Spanning Tree. Information includes the
	priority (hex) and MAC address of the root.
Path-Cost	Path-cost is the total path cost to the root bridge. It is the summation of the path cost
	between bridges (up to the root bridge).
Port	The current root port refers to the port on the GbE2 Interconnect Switch that receives data
	from the current root. Zero (0) indicates the root bridge of the STP.
Priority (bridge)	The bridge priority parameter controls which bridge on the network will become the STP
	root bridge.
Hello	The hello time parameter specifies, in seconds, how often the root bridge transmits a
	configurationbridge protocol data unit (BPDU). Any bridge that is not the root
	bridge uses the root bridge hello value.
