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.
VLT DOMAIN CONFIGURATION mode
system-mac mac-address mac-address
To explicitly configure 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 reconfigure 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.
7. When you create a VLT domain on a switch, Dell Networking OS automatically assigns a unique unit
ID (0 or 1) to each peer switch.
VLT DOMAIN CONFIGURATION mode
unit-id {0 | 1}
The unit IDs are used for internal system operations.
To explicitly configure the default values on each peer switch, use the unit-id command.
Configure a different unit ID (0 or 1) on each peer switch.
Use this command to minimize the time required for the VLT system to determine the unit ID
assigned to each peer switch when one peer switch reboots.
8. Configure enhanced VLT. 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
9. Place the interface in Layer 2 mode.
INTERFACE PORT-CHANNEL mode
switchport
10. Associate the port channel to the corresponding port channel in the VLT peer for the VLT connection
to an attached device.
INTERFACE PORT-CHANNEL mode
vlt-peer-lag port-channel id-number
Valid port-channel ID numbers are from 1 to 128.
Virtual Link Trunking (VLT)
Domain.
