Merge bandwidth of Two Wireless P2P link (Rocket M5)

[rao_harisali]

Hello Geniuses...

this is my 1st question in the Cisco world and i m very glad to discuss my queries with world best geeks.

I have a task to merge/combine bandwidth of multiple Radio (Rocket M5) with Cisco Switch, basically we need total throughput of 60 Mbps, but the Single UBNT Rocket M5 gave us just around 30 Mbps. Thats why we need to combine thier bandwidth with Cisco Switch.

1. I want to know it is possible or not?

2. How can i done this

Sorry for my english

Thanks in Advance.

Hi,

It looks like you are trying to implement something like this:-

SITE A LAN -- SWITCH-A ----- RADIO LINK 30M --- SWITCH-B -- SITE B LAN
SITE A LAN -- SWITCH-A ----- RADIO LINK 30M --- SWITCH-B -- SITE B LAN

You want it to look like

SITE A LAN -- SWITCH ----- RADIO LINK 60M (SHARED ACROSS 2 LINKS) --- SWITCH -- SITE B LAN

On your wswith you would aggregate the ports to the radio links using a port channel
also known as LAG.
So lets assume you want to trunk a couple of vlans 100 & 200 between the sites.
A config may be something along these lines:-

On switch A

interface port-channel 1
description *** AGG 60M Radio link to site B ***
switchport
switchport mode trunk
switchport trunk allowed vlan 100,200
no shut
!
interface gi1/0/1
description *** 30M Radio link 1 to site B ***
channel-group 1 mode
no shut
!
interface gi1/0/2
description *** 30M Radio link 2 to site B ***
channel-group 1 mode
no shut
!

On switch B

interface port-channel 1
description *** AGG 60M Radio link to site A ***
switchport
switchport mode trunk
switchport trunk allowed vlan 100,200
no shut
!
interface gi1/0/1
description *** 30M Radio link 1 to site A ***
channel-group 1 mode
no shut
!
interface gi1/0/2
description *** 30M Radio link 2 to site A ***
channel-group 1 mode
no shut
!

Hope this helps

bro...

you made similar scenario according to my need, but we have only 1 layer 3 Switch at each sites

[acampbell]

Hi,

I suggested a solution at layer 2 with only 1 switch at each end
that was why I shoed like:-

SITE A LAN -- SWITCH-A ----- RADIO LINK 30M --- SWITCH-B -- SITE B LAN
SITE A LAN -- SWITCH-A ----- RADIO LINK 30M --- SWITCH-B -- SITE B LAN

IE// SWITCH-A is the switch at A site
     SWITCH-B is the switch at B site

If you want it to be layer 3 its quite similar

On switch A

interface port-channel 1
description *** AGG 60M Radio link to site B LAYER 3 ***
no switchport
ip address 192.168.1.254 255.255.255.252
no shut
!
interface gi1/0/1
description *** 30M Radio link 1 to site B ***
no switchport
no ip address
channel-group 1 mode
no shut
!
interface gi1/0/2
description *** 30M Radio link 2 to site B ***
no switchport
no ip address
channel-group 1 mode
no shut
!

On switch B

interface port-channel 1
description *** AGG 60M Radio link to site A LAYER 3 ***
no switchport
ip address 192.168.1.253 255.255.255.252
no shut
!
!
interface gi1/0/1
description *** 30M Radio link 1 to site A ***
no switchport
no ip address
channel-group 1 mode
no shut
!
interface gi1/0/2
description *** 30M Radio link 2 to site A ***
no switchport
no ip address
channel-group 1 mode
no shut
!

Hope this helps

I want to ask

If one radoilink will disturb second or not?

Two radiolinks will work complitly independent?

[acampbell]

Hi,

The point of using a port-channel is to give
aggregation and redundancy.

When both links are up you would have a 60M path.
If one link fails you are down to 30M

Hope this helps

yes acampbell bro,

u said rite, thats all i want to do.

1 more question ....any loop are creating in this scenario of STP made any issues in this case,because we have to create loop actually.

[Tagir Temirgaliyev]

when you configure etherchannel you dont need to worry abot loops, there will be no loops

[rao_harisali]

Both radio links are working on different frequencies.

[acampbell]

Hi,

STP, port-channels not care about the radio frequencies.

They just see a layer 2 ethernet type point to point link.

So port channel with STP, STP just sees one link (your agg 60M)
