config stp

value ages out and a BPDU has still not been received from the

Root Bridge, the Switch will start sending its own BPDU to all

other switches for permission to become the Root Bridge. If it

turns out that your switch has the lowest Bridge Identifier, it will

become the Root Bridge.

The user may choose a time between 6

and 40 seconds. The default value is 20.

maxhops <value 1-20>

- The number of hops between devices in

a spanning tree region before the BPDU (bridge protocol data

unit) packet sent by the Switch will be discarded. Each switch on

the hop count will reduce the hop count by one until the value

reaches zero. The Switch will then discard the BDPU packet and

the information held for the port will age out. The user may set a

hop count from 1 to 20. The default is 20.

hellotime <value 1-10>

−

The user may set the time interval

between transmission of configuration messages by the root

device in STP, or by the designated router in RSTP, thus stating

that the Switch is still functioning. A time between 1 and 10

seconds may be chosen, with a default setting of 2 seconds.

In MSTP, the spanning tree is configured by port and

therefore, the

hellotime

must be set using the

configure stp ports

command for switches utilizing the Multiple Spanning Tree

Protocol.

forwarddelay <value 4-30>

−

The maximum amount of time (in

seconds) that the root device will wait before changing states. The

user may choose a time between 4 and 30 seconds. The default is

15 seconds.

txholdcount <value 1-10>

- The maximum number of BDPU Hello

packets transmitted per interval. Default value = 3.

fbpdu [enable | disable]

−

Allows the forwarding of STP BPDU

packets from other network devices when STP is disabled on the

Switch. The default is

enable

.

Restrictions

Only administrator-level users can issue this command.

Example usage:

To configure STP with maxage 18 and maxhops of 15:

DGS-3324SRi:4#config stp maxage 18 maxhops 15

Command: config stp maxage 18 maxhops 15

Success.

DGS-3324SRi:4#

config stp ports

Purpose

Used to setup STP on the port level.

Syntax

config stp ports <portlist> {externalCost [auto | <value 1-

200000000>] | hellotime <value 1-10> | migrate [yes | no] edge

[true | false] |

p2p [true | false | auto ] | state [enable | disable]
