SmartZone 100 (SZ104) - Discovering Multiple APs

[rajivw]

Planning to deploy 100+ APs in to a SZ cluster (2x SZ104). What's the best way to enable AP discovery by the WLC?

WLC IP is in 172.x.x.x/24 range (MGT). Do the APs have to be in the same range as the WLC to be discovered? If so, how can we enable 172.x.x.x range in all the APs? (Is the only option to use DHCP Option 43?)

All the APs are connected to the Switches and are under VLAN 100 (Untagged - 192.x.x.x DATA range). Will this be an issue for the discovery process, because those are in different subnets? 

Also we're using One-port Group Mode (Control+Data traffic). We don't mind using the 192.x.x.x range to manage the WLC as well, because there's no requirement for a separate MGT and DATA planes. 

Thanks in Advance.

Later on added DHCP configs (sorry, I don't have a copy of that config now). Just created a IP DHCP-Server pool, added network address of ve 40 above with subnet mask, excluded few addresses and deployed.

Dear @rajivw ,

Option 43 is supported from version 08.0.61 as you are running 08.0.60 the options command does not work. I attach screenshot from release notes of 08.0.61 for your reference, below.

I would recommend you to upgrade the switch to any of 08.0.90 or 08.0.90k (Recommend firmware as in Support Portal) if  there are no known issues that you may be aware.

Hope it helps.

Regards,

Abilash PR.

Hi @abilashpr 

Upgraded to 8.0.61. Op43 is there now. However DHCP server is not getting deployed. DHCP Server is deployed in Core SW of the network. APs are patched to other Access Floor Switches. Core - Access communication is working. Wireless VLAN is created on both Core & Access layers. VE interface with gateway IP is also configured on Core.

Dear @rajivw,

Yes, "ip dhcp-server enable" is not seen in the configuration, below is the working sample configuration.

!
!
!
aaa authentication web-server default local
aaa authentication login default local
boot sys fl pri
console timeout 30
enable aaa console
hostname Guest
ip dhcp-client disable
ip dhcp-server enable
!
ip dhcp-server pool iptv
 excluded-address 172.30.207.254
 lease 7 0 0
 network 172.30.204.0 255.255.252.0
 option  3 ip 172.30.207.254
 option  6 ip 8.8.8.8
 deploy
!

Please run " ip dhcp-server enable" in configuration mode, that should resolve your problem.

Hope it helps!!!
