Dell S4820T Configuration Manual page 1008

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