configuring multiple dynamic interfaces in 5508

Hi,

I have 5508 controller where as ap-manager interface configuration is optional but since i have different topology at other end , I have 4507 configured with HSRP and i want to divide the AP traffic in both the switches therefore I will have to go ahead and configure multiple AP-manager interface and map with two different physical ports.

But I have challenge to configure multiple dynamic interfaces.

I want to create two wlans ( Internal wlan and guest wlan )

Internal WLAN : 192.168.10.0

default gateway : 192.168.10.1

internal DHCP server : 172.16.10.1

Physical Port : ............... ?  which port to configure ? ( I have connectivity with port 1 & port 2 )

Guest WLAN : 192.168.20.0

Default gateway : 192.168.20.1

Internal DHCP server : 172.16.10.1

Physical port :  ............... ?  which port to configure ? ( I have connectivity with port 1 & port 2 )

I want to map it to multiple ports of dynamic interfaces for client traffic to physical ports.

how do i configure it ?

Hi Vinod,

if you go that way you will have to define one wlan for port 1 and one wlan for port 2.

To achieve total load-balancing of traffic between ports on WLC, it requires activation of LAG. And LAG requires one etherchannel on switch side and you cannot do this on 2 different switches.

Hope this helps.

Re: configuring multiple dynamic interfaces in 5508

Hi Nicolas,

Good to see your rapid reply.

Thanks for showing interest.


I have two different switches which has been configured with HSRP .. and i want to map multiple dynamic interfaces to two of the WLANs in WLC.

I am going to connect 5 APs to one of the switch and another 5 APs to other switch ?

I want to share the AP load in between two different core switches ..

How can i achieve it ?

I will be obliged to get solution of this .

Re: configuring multiple dynamic interfaces in 5508

You cannot.

And I'm not talking about a software specific restriction. It's a general truth AFAIK :

if you want to load balance between several devices, you need an external load balancer. You cannot expect one device to load balance between 2 switches as that will freak out the mac address tables everywhere.

So I'm sorry but it's a no go .

In adition to Nico's answer, I would go throught the detailed guide for the configuration of dynamic interfaces:
