HREAP and DHCP

Christopher Rosing — Sun, 04 Jul 2021 04:56:20 GMT

Hi All,

I have a Cisco 4402 wireless controller and I am trying to set up HREAP to dump traffic off locally. I have the HREAP function working as I can see my wireless MAC address on the correct vlan in the MAC table on various switches. The problem, the Wireless NIC isn't recieving a DHCP address. I have verified that my pool is operational. I connected a laptop to the same switch that the WAP is connected to and it pulls an IP address from that VLANs DHCP pool.

What am I missing? Another question is what interface to I set up for this WLAN? If it is going to be at a remote office, what should it be set to?

Thanks,

Chris

I would build a dummy interface and link the WLAN to that. That way if something goes wrong they can't go anywhere.

As for HREAP/FlexConnect do you have the WLAN mapped to the VLAN on the AP?

on the AP properties it is mapped. WLAN ID 4 to VLAN id 14. And I know that part is working because my Wireless NIC Mac is showing up on the right VLAN in the switch.

Can you post the config of the switchport the AP is connected to?

interface FastEthernet0/2

switchport trunk native vlan 13

switchport mode trunk

speed 100

duplex full

end

The native line is for the WAPs DHCP Config.

Chris,

Can you screen shot the AP config?

I went to go add a virtual interface on VLAN 14 and that brought down my access to the WLC. I rebooted and now I can pull IP addresses at my office. I have this WLAN in my Corporate office and now it is working just fine. I have now applied this WLAN to a remote office WAP (will be using the same vlan, just differnet subnet) and it won't pull an IP address. Again, I can see the MAC address on the swtich that is directly connected to the router with the IP Helper address and it still can't pull an IP address. This is a different switch from which the WAP is connected. If I plug a laptop into the same switch that the WAP is connected to, it pulls an IP address not problem.
