Conguring a VLT VLAN or LAG in a PVLAN
You can congure the VLT peers or nodes in a private VLAN (PVLAN). Because the VLT LAG interfaces are terminated on two
dierent nodes, PVLAN conguration 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 identied by
a primary and secondary VLAN pair. With VLT being a Layer 2 redundancy feature, support for conguration of VLT nodes in a
PVLAN enables Layer 2 security functionalities to be achieved. This section contains the following topics that describe how to
congure 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. Congure the port channel for the VLT interconnect on a VLT switch and enter interface conguration mode
CONFIGURATION mode
interface port-channel id-number.
Enter the same port-channel number congured with the peer-link port-channel command.
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.
