2504 WLC future LAG support?

We just bought a 2504 WLC with 15 AP licenses for our new eight 1141N AP installation.  Some confusion about LAG support for these now confirmed by TAC that LAG NOT supported for the time being.  Has anyone heard about whether this feature will be added to the 2504 in the future?  Seems a waste of those four ports toherwise.  Just wondering....

Re: 2504 WLC future LAG support?

I would think that it would not be supported in the future. They would probably end up with a different hardware platform to support LAG.

Re: 2504 WLC future LAG support?

If you mean a future software-release that will enable LAG on a 2500 then the answer is NO.

The reason, in my humble opinion (and not by inside information), is because the wireless BU does not want to take away unique customers of the 5508 to the 2500.

The 2500 would be best suited in a lab environment or in a very unique case where it's a remote site, one can't do H-REAP and doesn't need redundant link.  Why the 2500 has multiple uplink ports BUT can't support LAG is beyond my imagination.

Re: 2504 WLC future LAG support?

You can still utilize multiple links on the 2500 platform. If you create multiple interfaces with AP management enabled, you can load balance APs across the port(s).

Likewise, you can put your various wireless client vlans on different physical ports to avoid having ALL traffic on a specific port.

2504 WLC future LAG support?

FYI,

They just added LAG support for this controller in 7.4 code. I'm running

AIR-CT2500-K9-7-4-100-0.aes

2504 WLC future LAG support?

Hi Chellis,

We are evaluating 7.4 upgrade in order to use LAG on 2504.

Could you please be so  kind to confirm that:

1)802.3ad LACP is not supported and switch portchannel must be configured with mode on?

2)As soon you enable LAG all 4 ports are joined to a single channel and there is no way to have two channels with two joined ports each?

It's either LAG or no LAG.  You can't have both.
