We have a number of printers that by default have IPV6 configured though not used. ( not supported by me )
These printers are also connected to an IPV4 vlan where the IP address is allocated via DHCP and routed at a distribution switch X460.
Recently we had a issue with only the printers on the network , other devices on the same network , were able to operate and use the dhcp service and access the internet.
Only these printers would not work , if we connected a laptop to the switch port or disconnected the printer and used that port , the laptop would operate as expected.
We are being informed by the printer manufacturer that the issue we are seeing is that the Printer is creating an IPV6 broadcast storm , which I could understand , though my question is :
Would this not present itself the same as an IPV4 broadcast storm , CPU BCMrx high , vlan unresponsive etc?
This might be a IPV6 multicast issue as well ..
I.E the IPV4 network would also be effected .. which it was not.
I look forward to any comments and or suggestions .
