Product: LaserJet M452dn
Operating System: Microsoft Windows 7 (32-bit)

I have about half a dozen M452dn's on my network and am having a curious issue.  They are monitored by a Xerox XDA server.  

 

Symantec SEP is blocking the SNMP traffic port 161 UDP once per hour, thinking the M452dn's are causing flooding.   I have a similar number of M451dn's on the network as well and they do not cause this problem at all.   I also have numerous older HP4000's and they too do not cause any issues like this.

I have updated the firmware on the M452dn's to the latest available, disabled all un-needed protcols and turned off IPV6.  The problem continues whether I use SNMP read/write or read only, and stops when I disable SNMP but with it off the monitoring cannot continue so it has to be enabled.

The ports the M452's are sending to are random ports above 49152.
