=== Configuration of an Allegro as an '''ERSPAN''' sender ===


The Allegro Network Multimeter allows you to send '''ERSPAN''' packets via  the management interface  over a switched and routed network like a Pcap capture. Allegro recommend you use the '''ERSPAN''' sending feature only via the LAN interface and not with the Wi-Fi interface. Please see [#Limitations] for more details.

Please make sure that the sending Allegro MTU size is big enough to send the whole packet including the '''ERSPAN''' header. To configure the Allegro as an '''ERSPAN''' sender, increase the MTU size on the management interface AND on all Switches between the sending and receiving Allegro. This can be done at '''Settings''' → '''Management settings''' → '''LAN management interface'''.
