Hi Scott!I´m trying to find the AP SN on 9800 WLC, but this model does not have a "show ap inventory" command. I haven´t find it on GUI too.Do you know a way to find it?Thanks!Marcio

Hi Joseph, I found the information on links below, not exactly related to 2900 series, but for my case (2911 and 1941) it seems happen the same. https://supportforums.cisco.com/t5/wan-routing-and-switching/gre-bandwidth-restriction/td-p/2682012 h...

Hi Sreeraj. I had similar issue when the traffic over the GRE tunnel reaches 8M or above. I reserched and found out that this is a limitation bandwidth on GRE tunnel. As a workaround to avoid high CPU I put a rate-limit in 8M. HTH Marcio Ciano
