Service Manual

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.
4. Ensure that the port channel is active.
INTERFACE PORT-CHANNEL mode
no shutdown
5. Repeat Steps 1 to 4 on the VLT peer switch to congure the VLT interconnect.
Enabling VLT and Creating a VLT Domain
To enable VLT and create a VLT domain, use the following steps.
1. Enable VLT on a switch, then congure a VLT domain and enter VLT-domain conguration mode.
CONFIGURATION mode
vlt domain domain-id
The domain ID range is from 1 to 1000.
Congure the same domain ID on the peer switch to allow for common peering. VLT uses the domain ID to automatically create
a VLT MAC address for the domain. If you do not congure the system explicitly, the system mac-address of the primary will be
the VLT MAC address for the domain.
To disable VLT, use the no vlt domain command.
NOTE: Do not use MAC addresses such as “reserved” or “multicast.”
2. 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.
3. Congure the port channel to be used as the VLT interconnect between VLT peers in the domain.
VLT DOMAIN CONFIGURATION mode
peer-link port-channel id-number
4. (Optional) Prevent a possible loop during the bootup of a VLT peer switch or a device that accesses the VLT domain.
CONFIGURATION mode
lacp ungroup member-independent {vlt | port-channel port-channel-id}
LACP on VLT ports (on a VLT switch or access device), which are members of the virtual link trunk, is not brought up until the
VLT domain is recognized on the access device.
5. Repeat Steps 1 to 4 on the VLT peer switch to congure the IP address of this switch as the endpoint of the VLT backup link
and to congure the same port channel for the VLT interconnect.
Conguring a VLT Backup Link
To congure a VLT backup link, use the following command.
1. Specify the management interface to be used for the backup link through an out-of-band management network.
