Configuring Mesh Networking

9-21

The IT team selects the

Mesh STP Configuration

button on the bottom off the screen.

The Trion IT department sets the

Priority

setting to 1 (for AP1) in order for future members

of the mesh network to defer to AP1 as the AP defining the mesh network configuration
(setting this value to 1 AP1 to what is commonly referred to as the root).

The IT team leaves the

Maximum Message age

timer at the 20 sec default interval. This

setting controls the maximum length of time that passes before a bridge port saves its
configuration information. The

Hello Time

(the time between each bridge protocol data unit

sent) is also unchanged from 2 second default interval. The IT team also leaves the

Forward

Delay

(the time the AP-5131 LAN is spent in a listening and learning state) to the factory

default of 15 seconds. Since only one additional AP-5131 is to be added to this point-to-point
mesh network, the

Forwarding Table Ageout

value is also unchanged from its 100 second

default setting.

The team clicks

from within the Bridge STP Configuration screen and

Apply

from within

the trion (LAN1) screen to save the settings. This step is repeated for AP2.

The Trion IT team now intends to create a WLAN (to use with the trion LAN) that can be
dedicated to their mesh network within the shipping yard.

Select

Network Configuration

Wireless

from the AP-5131 menu tree.

NOTE

AP1 and AP2 have been configured identically up to this point. However,
only AP1 is assigned a priority of 1 within the Bridge STP Configuration
screen. AP2 is set to a lower priority (100) to keep AP1 as the root.
