Description

When configuring the same VLAN under both vlan members and native-vlan-id  on a trunk interface the switch tags the native VLAN on that specific interface

Symptoms


Solution

Configuration of native-vlan tagging:

ge-0/0/1 {
    unit 0 {
        family ethernet-switching {
             port-mode trunk;
            vlan {
                 members [ VLAN1 VLAN2 NATIVE ];
                  }
           native-vlan-id NATIVE;
       }
   }
}


When analyzing the output of the command show vlan , the trunk interface will appear twice under the NATIVE vlan-id
