General Discussion / Re: Question about LACP between OPNsense with Cisco 2960
« on: February 07, 2024, 11:59:37 am »
Just ran into the same/similar issue i.e. trying to pass VLAN tagged traffic over an LACP trunk to a Cisco 2960-S. The solution for me was to set the system MTU to 9000
conf t
system mtu jumbo 9000
A switch reboot is needed.
