Re: DHCP / VLAN

Here is output (is masked internal IPs)

Re: DHCP / VLAN

Is that the mac address of the client?  You would have to run that command multiple times in a row, to possibly see what is happening.

Re: DHCP / VLAN

Yes it is the mac adress of the client.

 

I've just tried again, running the command all the time of the connexion try.

 

For all the 1mn the client try to get an adress, wireshark shows only 3 gratuitous arp lines and debug command only the same line

 

34:F3:9A:BE:0A:23 1 0 0 0 0 dev14 3e00 -- -- F F 0

only the TAge changed.

 

I'm a little bit lost... I thought about a core switch misconfig, but no arp request is detected on port (by mirroring).

Re: DHCP / VLAN

Okay.  To be clear, the Virtual AP Vlan is set and the switch is tagged with that VLAN?

Re: DHCP / VLAN

If you are talking about the core switch where the AP is connected, yes.

 

AP mgmt adress is on a native VLAN 200 and core switch conf port is

 

interface FastEthernet1/0/47
switchport trunk native vlan 200
switchport trunk allowed vlan 200,151,152
switchport mode trunk
end

 

Virtual-AP VLAN is 151

 

wlan virtual-ap "WIFI-ACAD-2"
aaa-profile "WIFI-ACAD-2"
vlan 151
forward-mode bridge
ssid-profile "WIFI-ACAD-2"
!

 

when trying to connect, is can see on core switch

 

sh mac address-table | i 151

 

151 d85b.2a1d.8a67 DYNAMIC Fa1/0/47

Re: DHCP / VLAN

Okay.  Is there a DHCP server on VLAN 151?  I hate to ask that.

Re: DHCP / VLAN

Yes, ther eis an ip helper on this vlan, which relays arp request on DHCP server.

This VLAN and ip helper are already used by the "old infrastructure based on 3600" on the same core switch.

Re: DHCP / VLAN

Hi,

 

I finally found what was wrong : actually auth wasn't done. Client said it was searching for IP whereas it was not.

 

After solving this auth step, all is going well.

 

Sorry for disturbing.

 

Regards,
