Reference Guide

• TenGig 0/3 is a promiscuous port and TenGig 0/25 is a PVLAN trunk port, assigned to the primary
VLAN 4000.
• TenGig 0/4-6 are host ports. TenGig 0/4 and TenGig 0/5 are assigned to the community VLAN 4001,
while TenGig 0/6 is assigned to the isolated VLAN 4003.
The result is that:
• The S5000-2 ports would have the same intra-switch communication characteristics as described
previously for the S5000-1.
• For transmission between switches, tagged packets originating from host PVLAN ports in one
secondary VLAN and destined for host PVLAN ports in the other switch travel through the
promiscuous ports in the local VLAN 4000 and then through the trunk ports (0/25 in each switch).
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 S5000–2 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 S5000–1 switch in the topology diagram previously shown.
• Display the primary-secondary VLAN mapping. The following example shows the output from the
S5000–2.
show vlan private-vlan mapping
This command is specific to the PVLAN feature.
Examples of Viewing a Private VLAN using the show Commands
The show arp and show vlan commands are revised to display PVLAN data.
