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?
It does indeed! Thank you very much!
Now to my next question :-)
Why does a pretty recent IOS like c3640-jk9o3s-mz.123-14.T7.bin still have the advertisement of these frames as a default?
Considering things like security and running extra processes etc; shouldn't stuff like this be removed from the default behaviour of the IOS?
