Can't communicate with the standby IP

I can no longer communicate with the standby IP address configured on the inside interface of a secondary ASA5510. Just a couple days ago I could snmp, http, ssh, and ping it.

From the switch that is directly connected to the inside interface I'm getting unexpected results when viewing the the arp table. The switch is saying the IP address associated with the ASA's inside interface has mac address 0023.3353.bcc8 but the ASA is saying its inside interface mac address is 0023.33bb.8362

Furthermore when I issue the "sh mac address-table interface f5/46" command on the switch i see multiple macs on the interface that is connected to the inside interface of the ASA...

Can't communicate with the standby IP

Hi Bro

Maybe the 5/46 has been configured as a trunk port? Could you paste your switch and FW config here, so that everyone here can assist you.
