Description

Currently, pfSense uses C-Tags (ethertype 0x8100) for QinQ interfaces. Ideally, it should keep C-Tags on existing configuration but default to and provide the option to use S-Tags (ethertype 0x88A8).

In 23.01/2.7 the QinQ is handled by if_vlan directly and not netgraph. It now uses s-tags by default.

Since that's a change from the previous config it may fail for some setups making a setting there more important.

It is trivial to set at the command line though:

[23.01-DEVELOPMENT][admin@7100.stevew.lan]/root: ifconfig lagg0.4080 vlanproto 802.1Q
[23.01-DEVELOPMENT][admin@7100.stevew.lan]/root: ifconfig lagg0.4080
lagg0.4080: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=4600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6,NOMAP>
