Configuring a VLT VLAN or LAG in a PVLAN

You can configure the VLT peers or nodes in a private VLAN (PVLAN). Because the VLT LAG interfaces are

terminated on two different nodes, PVLAN configuration of VLT VLANs and VLT LAGs are symmetrical

and identical on both the VLT peers. PVLANs provide Layer 2 isolation between ports within the same

VLAN. A PVLAN partitions a traditional VLAN into subdomains identified by a primary and secondary VLAN

pair. With VLT being a Layer 2 redundancy feature, support for configuration of VLT nodes in a PVLAN

enables Layer 2 security functionalities to be achieved. This section contains the following topics that

describe how to configure a VLT VLAN or a VLT LAG (VLTi link) and assign that VLT interface to a PVLAN.

Creating a VLT LAG or a VLT VLAN

Configure the port channel for the VLT interconnect on a VLT switch and enter interface

configuration mode
CONFIGURATION mode

interface port-channel id-number.

Enter the same port-channel number configured with the peer-link port-channel command as
described in

Enabling VLT and Creating a VLT Domain

NOTE: To be included in the VLTi, the port channel must be in Default mode (no switchport
or VLAN assigned).

2. Remove an IP address from the interface.

no ip address

3. Add one or more port interfaces to the port channel.

INTERFACE PORT-CHANNEL mode

channel-member interface

interface: specify one of the following interface types:
• 1-Gigabit Ethernet: Enter gigabitethernet slot/port.
• 10-Gigabit Ethernet: Enter tengigabitethernet slot/port.
• 40-Gigabit Ethernet: Enter fortyGigE slot/port.
