Configuring Enhanced VLT (eVLT) (Optional)
To configure enhanced VLT (eVLT) between two VLT domains on your network, use the following procedure.
For a sample configuration, refer to
commands.
1
Configure the port channel to be used 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 in the
Enabling VLT and Creating a VLT
2
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.
3
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.
4
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.
5
Configure the IP address of the management interface on the remote VLT peer to be used as the
endpoint of the VLT backup link for sending out-of-band hello messages.
VLT DOMAIN CONFIGURATION mode
back-up destination {ipv4–address] | ipv6 ipv6–address [interval seconds]}
You can optionally specify the time interval used to send hello messages. The range is from 1 to 5
seconds.
6
When you create a VLT domain on a switch, the system automatically creates a VLT-system MAC
address used for internal system operations.
VLT DOMAIN CONFIGURATION mode

Example. To set up the VLT domain, use the following
