Conguring a VLT VLAN or LAG in a PVLAN
You can congure the VLT peers or nodes in a private VLAN (PVLAN). Because the VLT LAG interfaces are terminated on two dierent
nodes, PVLAN conguration 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 identied by a primary and
secondary VLAN pair. With VLT being a Layer 2 redundancy feature, support for conguration of VLT nodes in a PVLAN enables Layer 2
security functionalities to be achieved. This section describe how to congure 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 Congure the port channel for the VLT interconnect on a VLT switch and enter interface conguration mode
CONFIGURATION mode
interface port-channel id-number.
Enter the same port-channel number congured 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:
• For a 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the slot/port information.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information.
4 Ensure that the port channel is active.
INTERFACE PORT-CHANNEL mode
no shutdown
5 To congure the VLT interconnect, repeat Steps 1–4 on the VLT peer switch.
6 Enter VLT-domain conguration mode for a specied VLT domain.
CONFIGURATION mode
vlt domain domain-id
The range of domain IDs is from 1 to 1000.
