That is your default or you mean that being the default by the OS? For the latter all DSA ports are in untag state, check with bridge v
, e.g. prints
port vlan ids
lan0 1 PVID Egress Untagged
- untag state (one VID per each port only)
bridge v a dev lan1 vid 8 pvid untagged
- tag state
bridge v a dev lan1 vid 8 tagged
, or
bridge v a dev lan1 vid 8 pvid tagged
similar operation for a bridge port exchange the device name, e.g. dev lan1
with dev br-LAN2_IOT
.
