ExtremeWireless has RealCapture, and EOS can mirror into an L2GRE tunnel, are there any plans to add a similar feature to XOS so that I can easily use Wireshark on my desktop to inspect traffic? Competitors sometimes call this feature ERSPAN.
EXOS does not support GRE and there are no plans to do so. If you want to enable remote mirroring on an EXOS switch, you can use a seperate VLAN for it. Just do a search on "remote mirror" in the EXOS User Guide: http://www.extremenetworks.com/support/documentation/
