Configuring VLT

To configure VLT, use the following procedure.
Prerequisites:
Before you begin, make sure that both VLT peer switches are running the same Dell Networking OS
version and are configured for RSTP as described in
you configure VRRP groups and L3 routing on each VLT peer as described in VLT and VRRP
interoperability in the Configuration Notes
two switches are physically connected and treated as a single port channel by access devices, configure
the following settings on each VLT peer device.
1. Configure the VLT interconnect for the VLT domain. The primary and secondary switch roles in the
VLT domain are automatically assigned after you configure both sides of the VLTi.
NOTE: If you use a third-party ToR unit, to avoid potential problems if you reboot the VLT
peers, Dell recommends using static LAGs on the VLTi between VLT peers.
2. Enable VLT and create a VLT domain ID. VLT automatically selects a system MAC address.
3. Configure a backup link for the VLT domain.
4. (Optional) Manually reconfigure the default VLT settings, such as the MAC address and VLT primary/
secondary roles.
5. Connect the peer switches in a VLT domain to an attached access device (switch or server).
Configuring a VLT Interconnect
To configure a VLT interconnect, follow these steps.
1. Configure the port channel 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 as
described in Enabling VLT and Creating a VLT
NOTE: To be included in the VLTi, the port channel must be in Default mode (no switchport
or VLAN assigned).
2. Remove an IP address from the interface.
INTERFACE PORT-CHANNEL mode
no ip address
