C2504 with LAG and VLAN tagging

Having issues with setting up LAG on a Cisco 2504 WLC and implementing VLAN tagging on the different SSID´s.

Without LAG I had this up and running by using dynamic interfaces and assigning the different SSID´s to a perticular interface which was then assigned a specific VLAN.

However once I enabled LAG on the 2504, the dynamic interfaces became disabled and im unable to find documentation on how to configure VLAN tagging on SSID´s when using LAG.

Relevant info:

Cisco 2504 WLC running (FUS 1.8.0)

Cisco 2602 APs

Cisco 3560 switch running IOS 15 (c3560-ipbasek9-mz.150-2.SE3)

Switch output:

C3560-PoE8#show etherchannel 1 summary

Flags:  D - down        P - bundled in port-channel

        I - stand-alone s - suspended

        H - Hot-standby (LACP only)

        R - Layer3      S - Layer2

        U - in use      f - failed to allocate aggregator

        M - not in use, minimum links not met

        u - unsuitable for bundling

        w - waiting to be aggregated

        d - default port

Number of channel-groups in use: 1

Number of aggregators:           1

Group  Port-channel  Protocol    Ports


1      Po1(SU)          -        Fa0/1(P)    Fa0/2(P)    Fa0/3(P)


WLC output:

(Cisco Controller) >show lag summary

LAG Enabled


So basically what im trying to achieve is to implement LAG, use 2 SSID´s which are tagged in VLAN 300 and 400 respectively and keep management traffic untagged.

Re: C2504 with LAG and VLAN tagging

Did you reboot the WLC after you enabled LAG?

C2504 with LAG and VLAN tagging

Hi Scott,

Yes I did.. But it seems that after deselecting the "Interface/Interface Group(G)" under the SSID´s and then selecting the dynamic interface again that the problem is resolved.
