D-Link DES-3326S Layer 3 Switch

Configure the following STP Switch parameters and click the Apply button to implement them:

Parameter Description

Status <Disabled>

This field can be toggled between Enabled and Disabled using the pull-down

menu. This will enable or disable the Spanning Tree Protocol (STP),

globally, for the switch.

Max Age: (6 - 40 sec) <20 >

The Max. Age can be set from 6 to 40 seconds. At the end of the Max. Age,

if a BPDU has still not been received from the Root Bridge, your 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.

Hello Time: (1 - 10 sec) < 2 >

The Hello Time can be set from 1 to 10 seconds. This is the interval between

two transmissions of BPDU packets sent by the Root Bridge to tell all other

switches that it is indeed the Root Bridge.

Forward Delay: (4 - 30 sec) <15 >

The Forward Delay can be from 4 to 30 seconds. This is the time any port on

the switch spends in the listening state while moving from the blocking state

to the forwarding state.

Priority: (0 - 61440) <32768>

A Priority for the switch can be set from 0 to 61440. This number is used in

the voting process between switches on the network to determine which

switch will be the root switch. A low number indicates a high priority, and a

high probability that this switch will be elected as the root switch.

STP Version <RSTP >

Choose RSTP (default) or STP Compatibility. Both versions use STP

parameters in the same way. RSTP is fully compatible with IEEE 802.1d

STP and can function with legacy equipment.

Tx Hold Count <3 >

This is the maximum number of Hello packets transmitted per interval. The

count can be specified from 1 to 10. The default value = 3.

Forwarding BPDU <Enabled >

This can enabled or disabled. When it is enabled it allows the forwarding of

STP BPDU packets from other network devices when STP is disabled on the

switch. The default is enabled.

NOTE: The Hello Time cannot be longer than the Max. Age. Otherwise, a configuration

error will occur.

Observe the following formulas when setting the above parameters:

Max. Age ≤ 2 x (Forward Delay - 1 second)

Max. Age ≥ 2 x (Hello Time + 1 second)
