When configuring STP bridge parameters, the following formulas must be used:•2*(fwd-1)> mxage•2*(hello+1) < mxage

Spanning Tree port configuration

Command: /cfg/l2/stp <1-32> / port <port number>

[Spanning Tree Port		1 Menu]
prior	- Set	port	Priority (0-255)
cost	- Set	port	Path Cost (1-65535, 0 for default)
link	- Set port		link type (auto, p2p, or shared; default: auto)
edge	- Enables or disables this port as an edge port
on	- Turn port's Spanning Tree ON
off	- Turn port's Spanning Tree OFF
cur	- Display current port Spanning Tree parameters

By default for STP/PVST+, Spanning tree is turned Off for downlink ports (1-16), and turned On for uplink and cross- connect ports (17-24). By default for RSTP/MSTP, Spanning tree is turned On for all ports, with downlink ports configured as Edge ports.

Spanning tree port parameters are used to modify STP operation on an individual port basis. STP port parameters include:

•Port priority

•Port path cost

The following table describes the Spanning Tree Port Configuration Menu options.

Table 120 Spanning Tree Port Configuration Menu options

Command	Description
prior <0-255>	Configures the port priority. The port priority helps determine which bridge port becomes
	the designated port.
	In a network topology that has multiple bridge ports connected to a single segment, the
	port with the lowest port priority becomes the designated port for the segment.
	The range is 0 to 255, and the default is 128.
	RSTP/MSTP: The range is 0 to 240, in steps of 16 (0, 16, 32...) and the default is 128.
cost <1-200000000>	Configures the port path cost. The port path cost is used to help determine the designated
	port for a segment. Generally speaking, the faster the port, the lower the path cost.
	The range is 1 to 65535. The default is 10 for 100Mb/s ports, and 1 for Gigabit ports.
	A value of 0 indicates that the default cost will be computed for an auto-negotiated link
	speed.
	RSTP/MSTP: The range is 1 – 200000000, and the default it 20000 for Gigabit ports.
link autop2pshared	Defines the type of link connected to the port, as follows:
	auto: Configures the port to detect the link type, and automatically match its settings. This
	is the default value.
	p2p: Configures the port for Point-To-Point protocol.
	shared: Configures the port to connect to a shared medium (usually a hub).
	This command only applies when RSTP is turned on. See the “Common Internal Spanning
	Tree configuration” section for more information.
edge disableenable	Enables or disables this port as an edge port. An edge port is not connected to a bridge,
	and can begin forwarding traffic as soon as the link is up. Configure server ports as
	edge ports (enabled).
	This command only applies when RSTP is turned on. See the “Common Internal Spanning
	Tree configuration” section for more information.
on	Enables STP on the port.
off	Disables STP on the port.
