Conguring Enhanced VLT (eVLT) (Optional)
To congure enhanced VLT (eVLT) between two VLT domains on your network, use the following procedure.
For a sample conguration, refer to eVLT Conguration Example. To set up the VLT domain, use the following commands.
1 Congure the port channel to be used 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 in the Enabling VLT and Creating
a VLT Domain.
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 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.
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 Congure 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
system-mac mac-address mac-address
To explicitly congure the default MAC address for the domain by entering a new MAC address, use the system-mac command. The
format is aaaa.bbbb.cccc.
Also recongure the same MAC address on the VLT peer switch.
