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 as described in .
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.
4. Ensure that the port channel is active.
INTERFACE PORT-CHANNEL mode
no shutdown
5. To congure the VLT interconnect, repeat Steps 1–4 on the VLT peer switch.
6. Enter VLT-domain conguration mode for a specied 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.
VLT DOMAIN CONFIGURATION mode
peer-link port-channel id-number
The range is from 1 to 128.
