Inspecting the Private VLAN Configuration

The standard methods of inspecting configurations also apply in PVLANs.

To inspect your PVLAN configurations, use the following commands.
  • Display the specific interface configuration. INTERFACE mode and INTERFACE VLAN mode show config
  • Inspect the running-config, and, with the grep pipe option, display a specific part of the running-config. show running-config | grep string The following example shows the PVLAN parts of the running-config from the S50V switch in the topology diagram previously shown.
  • Display the type and status of the configured PVLAN interfaces. show interfaces private-vlan [interface interface] This command is specific to the PVLAN feature. For more information, refer to the Security chapter in the Dell Networking OS Command Line Reference Guide.
  • Display the configured PVLANs or interfaces that are part of a PVLAN. show vlan private-vlan [community | interface | isolated | primary | primary_vlan | interface interface] This command is specific to the PVLAN feature. The following examples show the results of using this command without the command options on the FN IOM switch in the topology diagram previously shown.
  • Display the primary-secondary VLAN mapping. The following example shows the output from the FN IOM switch. show vlan private-vlan mapping This command is specific to the PVLAN feature.
The show arp and show vlan commands are revised to display PVLAN data.

Example of Viewing a Private VLAN 

Dell#show vlan private-vlan

                                 ------- --------- --------- ------ ------------------------------------------

Example of the show vlan private-vlan mapping Command 

S50-1#show vlan private-vlan mapping
                                 Private Vlan:
                                 Primary     : 4000
                                 Isolated    : 4003
                                 Community   : 4001
  • NOTE: In the following example, notice the addition of the PVLAN codes – P, I, and C – in the left column.
