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 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 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 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport]
information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
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.
