Wireless Access

Hello community,

 

one of my customer has a cluster with two hardware controller, both are running fine so far. They have both the uplinke port 0/0/0, everything expect guest goes over this one.

 

They planned to seperate the guest network from the other networks, we are using the port 0/0/3 for guest traffic on the first controller, but the second controller doesnt have the possability for his own uplink. Is it possibly to get it running with this design or is it just impracticable?  At the moment the clients doenst even get ip addresses, even if the AP we are connected to is on the first controller (thats something i dont understand atm). We have IP Adresses on both controllers at the guest VLAN and the first controller is configured to act as a dhcp server.

 

I hope someone can clear this up for me.

 

Thank you in advance

It is doable , did you enable the DHCP service ?
Can you run the show ip dhcp database to confirm ?





Thank you

Hello,

 

thanks for the fast reply.

 

This is the ouput.

 

DHCP enabled

# vlan_53
subnet 172.18.30.0 netmask 255.255.255.0 {
option vendor-class-identifier "ArubaAP";
option vendor-encapsulated-options "192.168.200.241";
option domain-name-servers 80.58.61.250, 80.58.61.254;
option routers 172.18.30.1;
range 172.18.30.6 172.18.30.249;
authoritative;

Ok i did something stupid. The second controller didnt had an ip address on the guest vlan. I configured it but didnt pushed it because i waited for an firmware upgrade to complete and i was afraid it could be interupted.

This fixed the whole problem and all clients getting ip adresses and internet access on all APs.

 

Still thanks for the help and have a good day.

Good monday,

 

its me again. It seems that the testing client connected over the first controller (which has the uplink to the guest router). Over the weekend my customer did some further tests and some clients still dont get any ip. As far as i understand it, clients are not necessarily connected to the same controller as the ap they are joined on (AP-3 is connected to controller 1 but the client on AP-3 are on controller 1 or 2, depends on the mac).

So clients who join the second controller doesnt have a uplink. What do i need to change that all clients in the Guest SSID only use the uplink port 0/0/3 from the first controller?

 

Regards Patrick

I would appreciate if someone could explain me how to fix the problem with only one physical uplink as i explained in my post.

 

Thank you in advance.
