I've deployed my first AOS-CX 6100 switch and I'm having issues getting IP phones to work properly. I'm using dot1x for wired computers and MAB for the phones configured on the same switch port. This appears to be working properly with the hosts and the phones being assigned the correct vlan. I have a Cisco router that is handing out DHCP to the phones. All the phones are getting the correct DHCP addresses but only a few are actually showing up in the ARP table. I'm starting to suspect that something is going on with LLDP since I'm seeing a lot of the following log entries.
2021-09-23:12:39:02.208259|ovsdb-server|LOG_ERR|AMM|-|DB|DB_ALL|constraint violation: Transaction causes multiple rows in "LLDP_Neighbor" table to have identical values (708eef8a-5de4-42ce-bf6c-1906ffbf826b, "0001", and "08:00:0f:b5:76:50") for index on columns "interface", "chassis_id", and "port_id". First row, with UUID c0a0810d-7af3-4007-8fdc-10c9adf95e3b, existed in the database before this transaction and was not modified by the transaction. Second row, with UUID d945d835-749d-47d5-9743-405c0a097e34, was inserted by this transaction.
Does anyone know what this log entry means?
