Cisco WLC 2504 with an unmanaged switch

Jasim.Mohiuddin · ‎05-23-2015

I am using a linksys router, a 2504 WLC with 5 AP's along with an unmanaged 8 port switch.

All these devices are on the same subnet 192.168.100.X with dhcp configured on wlc.

The management IP address of the wlc is untagged and the default gateway is set to the linksys router (for internet access).

The clients are able to ping the WLC & AP's but they are unable to reach the linksys router and thereby have no internet access. WLC will not ping its default gateway.

On connecting a PC to the unmanaged switch with default gateway as the router ip will enable internet access on the pc, so my question is do we need to form a trunk port between the wlc & switch even when the subnet is untagged?

I thought that having the traffic untagged will allow the clients to have internet access or is there some configuration which I have missed?

Thanks

Hi,

Yes, I think the connection between WLC and the switch needs to be a trunk port

By default, all four ports on the Cisco 2500 Series Wireless Controller are 802.1Q trunk ports. The controller is always connected to a Gigabit Ethernet port on the neighboring switch. The neighbor switch port is configured as an 802.1Q trunk and only the appropriate VLANs are allowed on the trunk. All other VLANs are pruned. This is not necessary, but is a deployment best practice because when irrelevant VLANs are pruned, the controller only processes relevant frames which optimizes performance.
