Hi Guys,
This issue has completely stumped me and am hoping you can help.
Situation is as follows:
I have two 7205 controllers setup as active-standby across 2 sites. I also have two DHCP servers at each site. I set up a new scope for clients on the DHCP server where the standby controller is and wanted to set it up so that all clients get their IPs from that DHCP server.
Site A = master controller and backup DHCP server
Site B = standby controller and main DHCP server
I have set up 2 AP System Profiles: One of them is configured so that the Site A controller is the LMS with the Site B controller as the backup LMS (SysProfileA) and the other profile configured vice versa (SysProfileB).
A DHCP helper address has been set on the client VLAN to the main DHCP server at site B.
I also set up AP groups for each site and set the respective AP system Profiles. So "SysProfileA" in the "Site A" AP group and "SysProfileB" on "Site B" AP group... and this is where the problem starts:
Clients are able to get IP addresses fine at Site B.
Clients cannot get IP addresses at Site A.
The only way to get clients at Site A to get IPs is by changing the AP (one which I'm testing) to come under the Site B AP group (and thus the LMS being the standby rather than the master) which is what I don't want. I have compared the two AP System Profiles and they are both identical with the exception of which controller is the LMS.
I hope I have been able to articulate this issue as it's almost confusing just to describe it.
If you need more info or configs I am happy to provide it.
Thanks
