6500 netdr strange srcmac 0000.XY00.0000

Hi Guys

with the netdr capture i'm getting the frames like below on the different 6500 platforms with srcmacs i totally can't understand. Please save my mind with explanation :)

Re: 6500 netdr strange srcmac 0000.XY00.0000

Cisco used to have a program called netdir parser just for this but they removed it off their site in January this year. It is advised to use Wireshark instead because it is the defecto program to analyze packet captures for all network landscapes.

Hi Kevin

It's quite a pity to have Netdr parser decomissioned... And actually i dont understand how Wireshark can be used in parsing pure Netdr output...

Anywas topic was about strange MAC addresses similar to 0000.0500.0000 & 0000.1500.0000.
