CONFIGURATION mode
interface port-channel id-number
Enter the same port-channel number congured with the peer-link port-channel command.
2. Add one or more port interfaces to the port channel.
INTERFACE PORT-CHANNEL mode
channel-member interface
interface species one of the following interface types:
• 10-Gigabit Ethernet: Enter tengigabitethernet slot/port.
• 40-Gigabit Ethernet: Enter fortygigabitethernet slot/port.
3. Enter VLT-domain conguration mode for a specied 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 will act as the interconnect trunk.
VLT DOMAIN CONFIGURATION mode
peer-link port-channel id-number
The range is from 1 to 128.
5. Congure 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, the system automatically creates a VLT-system MAC address used for internal
system operations.
VLT DOMAIN CONFIGURATION mode
system-mac mac-address mac-address
Use the system-mac command to explicitly congure the default MAC address for the domain by entering a new MAC
address in the format: aaaa.bbbb.cccc.
You must also recongure 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, the system automatically assigns a unique unit ID (0 or 1) to each peer switch. The
unit IDs are used for internal system operations.
VLT DOMAIN CONFIGURATION mode
unit-id {0 | 1}
Use the unit-id command to explicitly congure the default values on each peer switch.
