Deployment Guide

NOTE: Even after you disable ip-local-proxy-arp (no ip-local-proxy-arp) in a secondary VLAN, Layer 3
communication may happen between some secondary VLAN hosts, until the ARP timeout happens on those secondary VLAN
hosts.
Inspecting the Private VLAN Conguration
The standard methods of inspecting congurations also apply in PVLANs.
To inspect your PVLAN congurations, use the following commands.
• Display the specic interface conguration.
INTERFACE mode and INTERFACE VLAN mode
show config
• Inspect the running-cong, and, with the grep pipe option, display a specic part of the running-cong.
show running-config | grep string
The following example shows the PVLAN parts of the running-cong from the S50V switch in the topology diagram previously shown.
• Display the type and status of the congured PVLAN interfaces.
show interfaces private-vlan [interface interface]
This command is specic to the PVLAN feature.
For more information, refer to the Security chapter in the Dell Networking OS Command Line Reference Guide.
• Display the congured PVLANs or interfaces that are part of a PVLAN.
show vlan private-vlan [community | interface | isolated | primary | primary_vlan | interface
interface]
This command is specic 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 specic 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
Primary Secondary Type Active Ports
------- --------- --------- ------ ------------------------------------------
20 Primary Yes Te 1/1,5
30 Community Yes Te 1/2
40 Isolated Yes Te 1/3
Dell#
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.
