LevelOne GSW-1290 Gigabit Layer2 SNMP Switch

Configure the following system-wide STP parameters and click the

Apply

button to implement them:

Parameter

Description

Spanning Tree
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.

Bridge 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.

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.

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.

Bridge 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 will function with legacy equipment.

Tx Hold Count(1-10)

<

3

>

This is the maximum number of Hello packets transmitted per interval.
The count can be specified from

1

to

10

. The default value is

3

.

Forwarding BPDU

<

Enabled

>

This can be

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)
