Conguring Enhanced VLT (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 .
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:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the stack/slot/port/subport information.
• For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then the stack/slot/port/subport information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the stack/slot/port[/subport] information.
• For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the stack/slot/port/subport information.
• For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then the stack/slot/port information.
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
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 ip-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, Dell Networking OS automatically creates a VLT-system MAC address used for internal
system operations. To explicitly congure the default MAC address for the domain by entering a new MAC address, use the following
command.
VLT DOMAIN CONFIGURATION mode
system-mac mac-address mac-address
The format is aaaa.bbbb.cccc.
Also recongure the same MAC address on the VLT peer switch.
Use this command to minimize the time required for the VLT system to synchronize the default MAC address of the VLT domain on
both peer switches when one peer switch reboots.
