NME-NAM Capture sources

Forum

I am working today with an NME-NAM that we recently configured at a customer site. 

When setting up a Capture Filter on the NAM, there are 3 options underneath the pull down for "Capture From" which are:

Internal - External - ERSPAN.

I understand that the Internal interface is the router interface the way we have it set up.  External is the RJ45 port that we can use on the NAM for sniffing.

I am not sure what "ERSPAN" is for.  I do understand what SPAN (port monitor/port mirror) is and use it all the time in my work.

thanks

Kevin

Re: NME-NAM Capture sources

ERSPAN is Enhanced Remote SPAN.  Using ERSPAN you can forward SPAN data over a layer 3 network.  ERSPAN is only supported on the Cat6K and 7600 NAMs.
