Adding Two more Wireless bridges - Etherchannel

[s.kanth]

Two facilites are connected via wireless bridge(AIR-BR1410A-E-K9).

we wanted to add wireless bridge at each facility to increase the bandwidth.

So we will have two wireless bridge at each facility connected wirelessly.

and we wanted to achieve it by doing some kind of etherchannel in the switches at each location... will it work ? please advise.

Thanks

You can, but normally you would use spanning tree to load balance the vlans across the two links especially if your going to be layer 2 or else spanning tree will only pass traffic thought one link and not the other. So set your spanning tree vlan priority and you should be set.

Yes, we want to go for Layer2. Two ports will be bundled at each switch of sites.

So STP vlan priority to be set (VLAN1 traffice goes one link and VLAN2 goes secondary link.)

AM I right or missed somthing.?

Thank

Nope... That is exactly how you have to set it up.

I would like to transfer vlan 3 traffic over TOP left bridge and vlan 10 over left bottom bridge.

Plan would be...

Can two left site bridges be made as root bridge.

1. TOP left bridge will be root for vlan 3

2. Boot left bridge will be root bridge for vlan 10.

Can you please share configuration ?

I do really appreciate your understanding and cooperation on this plan.

Hi ,

Here is the plan…

• Top left bridge will be Root Bridge for VLAN3 and only vlan 3 traffic is traversed.
• Bottom left bridge will be Root Bridge for VLAN 10 and only vlan 10 traffic is traversed.
• If any one of the bridge/link goes down, traffic will be diverted to other link automatically.
• By doing this we can use both of the links effectively.

Configuration is attached.. please let us know your ideas/// (Or would it work)?
