++ ARP reply is dropped by Polaris - cat3K and cat9k when IPDT policy gleans from ARP. ++ This can cause issues like one-way audio when IPDT is enabled on the switch that connects to one of the IP phones but not on the switch that connects to the remote IP phone.
IPDT gleans from protocol arp. For example : device-tracking policy TEST protocol arp
Remove protocol arp gleaning from the device-tracking policy. For example : device-tracking policy TEST no protocol arp
This issue has been observed on both cat3K and on cat9K. (16.9.2 and 16.6.4 is where this was initially found)
