Greetings, I'm working on a project where I need to span all data from a vmware vds switch to a packet capture device. Since the capture appliance is a few hops away, I want to use ERSPAN. VMware VDS allows ERSPAN and also has the option to slice packets at a determined length (mirrored packet length). The default length is 60 bytes. If I'm only interested in source/destination IP address and source/destination port/protocol, how can I determine the lowest possible packet length? My goal is to minimize bandwidth usage and make this as efficient as possible. Thanks!
