Description

This article explains the meaning of the interfaces marked with an asterisk. 
 

Solution

To identify which VLAN traffic belongs to, all frames on an Ethernet VLAN are identified by a tag, using VLAN tagging, hosts within each organization can be tagged with a different VLAN identifier. Traffic sent to the broadcast domain is then checked against the VLAN identifier and broadcast to only the devices in the appropiate VLAN. Below you can see and output example:
  
root@EX3300-1# run show vlans

Name           Tag     Interfaces
NATIVE         1       ge-0/0/23.0*

The interface ge-0/0/23.0 is being part of an specific vlan as it has the asterisk on the detail, which means the interface is being tagged.

If we check the configuration we can see the interface is being part of vlan Cust_150 Cust_151, please see below:


ge-0/0/23 {
    unit 0 {
        family ethernet-switching {
            port-mode trunk;
            vlan {
                members [ Cust_150 Cust_151 ];
