Anyone put two wlans on two wisms into one subnet?

Unanswered Question
Feb 25th, 2008

We have two WiSM blades on one C6500 switch. We use WiSMs as DHCP relay pointing to central DHCP. Because of the lack of IP subnets, we want to use one /22 subnets for the two WLANs(same SSID) on two wisms. Anyone tried this? Any problems with this setup?



I have this problem too.

No, not really the AP groups. My senario is as follows:

Say I have WLAN/SSID ABC on controller A of the WiSM 1. The WLAN ABC is assigned with subnet x.y.z.0/24. Now I want to add WiSM 2 to the same CAT6500 chassis. I need to create WLAN/SSID ABC on controller A of WiSM 2 as well. The most important is I want the WLAN ABC on WiSM 2 to use the same subnet x.y.z.0/24. So I will have one subnet across two WiSM modules. Is it ok to do this?

Yes.... you will just need to create a dynamic interface on both WLC for the subnet. Then when you create an ssid ABC, you map that ssid to that dynamic interface you created.
