Verifying That a Private VLAN Is Working

Purpose

After creating and configuring private VLANs, verify they are set up properly.

Action

1. Use the show configuration vlans command to determine if you successfully created the primary and secondary VLAN configurations:
   user@switch> show configuration vlans

   community1 {
       interface {
           interface a;
           interface b;
       }
       primary-vlan pvlan;
   }
   community2 {
       interface {
           interface d;
           interface e;
       }
       primary-vlan pvlan;
   }
   pvlan {
       vlan-id 1000;
       interface {
           isolated1;
           isolated2;
           trunk1;
           trunk2;
       }
       no-local-switching;
   }

2. Use the show vlans command to view VLAN information and link status:
   user@switch> show vlans pvlan extensive

   VLAN: pvlan, Created at: time
   802.1Q Tag: vlan-id, Internal index: index-number, Admin State: Enabled, Origin: Static
   Private VLAN Mode: Primary
   Protocol: Port Mode
   Number of interfaces: Tagged 2 (Active = 0), Untagged  6 (Active = 0)
         trunk1, tagged, trunk
         interface a, untagged, access
         interface b, untagged, access
         interface c, untagged, access
         interface d, untagged, access
         interface e, untagged, access
         interface f, untagged, access
         trunk2, tagged, trunk
   Secondary VLANs: Isolated 2, Community  2
     Isolated VLANs :
         __pvlan_pvlan_isolated1__
         __pvlan_pvlan_isolated2__
     Community VLANs :
         community1
         community2

3. Use the show ethernet-switching table vlan command to view logs for MAC learning on the VLANs:
   user@switch> vlan pvlan extensive

   pvlan, *
     Interface(s): trunk1
     Interface(s): interface a
     Interface(s): interface b
     Interface(s): interface c
     Interface(s): interface d
     Interface(s): interface e
     Interface(s): interface f
     Interface(s): trunk2
     Type: Flood
     Nexthop index: 1344
   

Meaning

The output shows that the primary and secondary VLANs were created and associated and displays MAC learning information.
