Private VLAN (PVLAN)

Overview

The Private VLAN (PVLAN) feature of FTOS is supported on Dell Force10

platforms as indicated by the characters that appear under each of the command

headings:

c C-Series, s S-Series, , or .

Commands

• ip local-proxy-arp

• private-vlan mode

• private-vlan mapping secondary-vlan

• show interfaces private-vlan

• show vlan private-vlan

• show vlan private-vlan mapping

• switchport mode private-vlan

Refer also to the following commands. The command output is augmented in FTOS

7.8.1.0 to provide PVLAN data:

• show arp in IPv4 Routing

• show vlan in Layer 2

Private VLANs extend the FTOS security suite by providing Layer 2 isolation

between ports within the same private VLAN. A private VLAN partitions a

traditional VLAN into subdomains identified by a primary and secondary VLAN pair.

The FTOS private VLAN implementation is based on RFC 3069.
