As addition to ERSPAN info you've received from
list you might want to check these out:

http://cisco.cluepon.net/index.php/ERSPAN_to_PCAP_script
 - python script to listen for ERSPAN packets and dump
   them as pcap

http://ip.fi/hacks/README-pcapop.txt
http://ip.fi/hacks/pcapop
 - ruby script to pop X amount of bytes from pcap
   file. Per default pops ERSPAN headers.

python version makes more sense, if you're starting
your debug session now. ruby version makes more
sense if you already are in possession of pcap
capture of ERSPAN and want to have something
useful to look at in eg. wireshark.
