1. Create a VLT domain and configure VLTi.
OS10(config)# interface range ethernet 1/1/4-1/1/5
OS10(conf-range-eth1/1/4-1/1/5)# no switchport
OS10(conf-range-eth1/1/4-1/1/5)# exit
OS10(config)# vlt-domain 1
OS10(conf-vlt-1)# discovery-interface ethernet 1/1/4-1/1/5
2. Configure a VLT MAC address.
OS10(conf-vlt-1)# vlt-mac 12:5e:23:f4:23:54
3. Specify the management IP address of the VLT peer as a backup link.
OS10(conf-vlt-1)# backup destination 10.10.10.1
4. Configure VLT port channels.

Verify DHCP snooping on both VLT peers
The following output shows that the DHCP snooping switches (VLT peers) snooped DHCP messages. The interface column displays the
local VLT port channel number.
