connectivity from 5508 to two different 4507 switches

Hi,

I have set up with 5508 controller which is connected to two different chassis ( Cisco 4507 switches ) . I have doubt about interface configuration on 5508 WLC.

How do i configure AP-manager interface with two physical ports on different chassis?

As i understood , we can configure AP-manager interface with only one port

In my set up we have configured HSRP with mentioned chassis ...

Please light on this confused concept.

how can i configure the interfaces with two physical ports on two different chassis ?

If anybody could send configuration sample , it would be great help for me to procees with.

Already there is query for the same in cisco forum but i could not understand properly.

Answer would be appreciative.

Re: connectivity from 5508 to two different 4507 switches

Hi,

I would advise you to go through the doc:

http://www.cisco.com/en/US/docs/wireless/controller/7.0/configuration/guide/c70mint.html.

For Cisco 5500 Series Controllers, you are not  required to configure an AP-manager interface. The management interface  acts like an AP-manager interface by default, and the access points can  join on this interface.

Re: connectivity from 5508 to two different 4507 switches

Hi,

With multiple AP-manager interfaces, you can  connect your ports to different neighbor devices. If one of the neighbor  switches goes down, the controller still has connectivity. However,  using multiple AP-manager interfaces presents certain challenges when port redundancy is a concern.

http://www.cisco.com/en/US/docs/wireless/controller/7.0/configuration/guide/c70mint.html#wp1294453.

Before an access point joins a controller, it  sends out a discovery request. From the discovery response that it  receives, the access point can tell the number of AP-manager interfaces  on the controller and the number of access points on each AP-manager  interface. The access point generally joins the AP-manager with the  least number of access points. In this way, the access point load is  dynamically distributed across the multiple AP-manager interfaces.

Please note that access points may not be distributed completely  evenly across all of the AP-manager interfaces, but a certain level of  load balancing occurs.

Please make sure that:


Note Do  not define a backup port for an AP-manager interface. Port redundancy  is not supported for AP-manager interfaces. If the AP-manager interface  fails, all of the access points connected to the controller through that  interface are evenly distributed among the other configured AP-manager  interfaces.


Step 6 To make this interface an AP-manager interface, select the Enable Dynamic AP Management check box.

HTH,

Tiago

Re: connectivity from 5508 to two different 4507 switches

Hi,

Thanks for your reply.

I gone through the same document and understood that ap-manager interface is optional.

But If I want to connect two ports to two different chassis of 4507 , what kind of challanges i have ?

And in case I have 10 access point and i want to load share in between in these two switches , how do i configure WLC for this load-sharing .

As I mentioned , if you could send at least some configuration template or configuration to me .

It would be great help for me .

looking forward for your reply....
