Hi All,

I am using Cisco 2800 AIR-AP2802I-A-K9 use in standalone mode as a controller and access point. I have created 

3 ssid on it. My problem is test1 ssid broadcast arp request is seeing on test2 ssid. 

Is there any way to disable this.

Thank you all in advance

Are the two SSID attached to the same VLAN?
What software version are you running on the AP/ME?

[samir_1976]

Hi,

Both SSID on different VLAN and software version 8.5.140.0

Interesting, could you create a pcap on both testclients and upload it here with the ARP packages in it?

Hello,

FYI,

It was bug in Cisco 2800 as per the think link.

We upgrade our software from 8.5.140.0 to 8.5.151.0 and it resolved the issue
