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.
