On troubleshooting we found that on core switch ARP will happen for all APs connected in LAN. I am getting ARP of all other APs but except one AP which has issue.  Interface VLAN of all AP is configured on core & AP is connected to access switch on access port. I did clear ARP on core switch & , clear MAC address core and access  switches but no positive results. on access switch when i do show cdp on connected interface i see IPv6 address I suspecting issue with DHCP.  What do you say friends? Please  suggest.   Thanks in advance.   ... View more
