wlc 5508 distribution ports

[Kamran Mustafayev]

Hi everyone,

I wonder how many distribution ports should i use to connect 5508 to 6500, where can i get the instruction about it, or it depends on amount of access points, or i should connect all 8 ports in lag

thank you

This is depend on how many AP managed by this controller & what is the total wireless traffic volume you may have. If you have more than 200+ AP (802.11n supports where single AP can give ~450 Mpbs max) & heavy use of wireless (ie video,heavy downloads through wireless), I would  go ahead and bundle all 8 ports into single 8Gbps LAG.

Keep in mind, WLC does not support any etherchannel negotiation protocols (LACP or PAgP). So you have to configure "channel group mode on" command on switch side when port aggregating. Also unless you have 6500 pair of VSS, all physical ports from WLC LAG ports to be connected to same physical switch.

Here is the configuration guide reference for WLC 7.4.x software code

Please find the link below where its mentioned clearly that:-

You  can bundle all four ports on a 4404 controller (or two on a 4402  controller) or all eight ports on a 5508 controller into a single link.

Also you can find the configuration to configure the same..
