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 1. 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. INTERFACE PORT-CHANNEL mode 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. 4. Ensure that the port channel is active. INTERFACE PORT-CHANNEL mode no shutdown 5. To configure the VLT interconnect, repeat Steps 1-4 on the VLT peer switch. 6. Enter VLT-domain configuration mode for a specified VLT domain. CONFIGURATION mode vlt domain domain-id The range of domain IDs is from 1 to 1000. 7. Enter the port-channel number that acts as the interconnect trunk. 1106 Virtual Link Trunking (VLT)
