The tag in the frame(vlan id)is in accord with the access port vlan id. The situation like one site is trunk mode port but another side is access mode port
HI Vignesh R P,Thank you! Some vender like HuaWei will accept the frame with tag in the access port if the tag vlanID is the same to the access vlanID.So,I am not sure CISCO will drop or not before you reply to me.Best Regards,Ti Huang
