Can somebody shed any light on this? Or even know who to alter this behaviour(filter, disable, etc)?
I have a capture running on an ethernet interface of a 3640 with IOS c3640-jk9o3s-mz.123-14.T7.bin
CDP and keepalives are disabled, no routing, no ip addresses configured.
Still Wireshark shows me that the interface is sending frames with a protocol id of 0x6002 (DEC DNA Remote Console) around every 515 to 705 seconds.
What are these frames for?
