ERSPAN on Cumulus VX


Hi, all!

Does Cumulus VX supports ERSPAN?
I make such rules in ACL:
-A FORWARD --in-interface swp+ -j ERSPAN --src-ip 192.168.100.1 --dst-ip 192.168.203.25 --ttl 64

But counters in compiled rulles are zeroes after I started to pass traffic over swp interfaces.

Best regards,
Anton Lopatin.

SPAN and ERSPAN are handled by the switching ASICs in Cumulus Switches, those features will not function in VX as there is no ASIC.

It's clear. It's a pity that there is now virtual ASIC for this function 🙂
Thanks for the clarification!
