Service Manual

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:
• For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet then the slot/port information.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the 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
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 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 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.
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 congure the default values on each peer switch, use the unit-id command.
Congure a dierent unit ID (0 or 1) on each peer switch.
