Cisco WLC 2504 HA deployment issue!

[bepeen]

Hello,

I'm getting high latency in my WLAN after deploying 2504 controller with 2504 HA:

Since, primary secondary fail-over is working I guess the configuration should be okay.

This is the case:

While connecting only Primary controller there is no latency,

While connecting only Secondary controller there is no latency,

While connecting both controller there is a high latency,

There're no any proper deployment guides for the 2504 controllers! 

Here I've attached configuration file, please take a look and suggest me the correct process.

I would highly appreciate your any advice.

While connecting both controller there is a high latency,

What do you mean by this?

Fail-over between primary and secondary worked but there is a high latency form end users.

Ping result from end users to default-gateway is above 1000ms while connecting both WLC, but it's normal (1-4ms) either unplugging HA or Primary controller from L3 Switch.

When using the WLC as a dhcp server, you need to make sure the dhcp scope doesn't not overlap. You need to split the address pool so that each controller hands out a different range of address.  You should see issues regarding duplicate IP address on some of the clients.  Fix that and things should work better.
