I have a group of SM’s off the same AP that have communication problems. When local to the SM I can not see or get to any device on the networks beyond the AP. From bot sites I can see the AP and get to it. If I telnet to the AP and then telnet from the AP to the switch and then from that switch to any site and start a ping back to my local switch I can then reach that device but only the one pinging back? I have compared the SM’s and AP’s with others in my network and they appear the same yet this one AP is still acting up no others. Running version 16.1. It appears that this AP is blocking arp requests or loosing arp information with the local switch and both SM’s but I can’t find any setting that would cause this and comparing with every other AP and switch this location is configured the same but not working the same.
