Additional VLT Sample Configurations
To configure VLT, configure a backup link and interconnect trunk, create a VLT domain, configure a backup link and interconnect
trunk, and connect the peer switches in a VLT domain to an attached access device (switch or server).
Review the following examples of VLT configurations.
Configuring Virtual Link Trunking (VLT Peer 1)
Enable VLT and create a VLT domain with a backup-link and interconnect trunk (VLTi).
Dell_VLTpeer1(conf)#vlt domain 999
Dell_VLTpeer1(conf-vlt-domain)#peer-link port-channel 100
Dell_VLTpeer1(conf-vlt-domain)#back-up destination 10.11.206.35
Dell_VLTpeer1(conf-vlt-domain)#exit
Configure the backup link.
Dell_VLTpeer1(conf)#interface ManagementEthernet 1/1
Dell_VLTpeer1(conf-if-ma-1/1)#ip address 10.11.206.23/
Dell_VLTpeer1(conf-if-ma-1/1)#no shutdown
Dell_VLTpeer1(conf-if-ma-1/1)#exit
Configure the VLT interconnect (VLTi).
Dell_VLTpeer1(conf)#interface port-channel 100
Dell_VLTpeer1(conf-if-po-100)#no ip address
Dell_VLTpeer1(conf-if-po-100)#channel-member fortyGigE 1/49,50
Dell_VLTpeer1(conf-if-po-100)#no shutdown
Dell_VLTpeer1(conf-if-po-100)#exit
Configure the port channel to an attached device.
Dell_VLTpeer1(conf)#interface port-channel 110
Dell_VLTpeer1(conf-if-po-110)#no ip address
Dell_VLTpeer1(conf-if-po-110)#switchport
Dell_VLTpeer1(conf-if-po-110)#channel-member fortyGigE 1/51
Dell_VLTpeer1(conf-if-po-110)#no shutdown
Dell_VLTpeer1(conf-if-po-110)#vlt-peer-lag port-channel 110
Dell_VLTpeer1(conf-if-po-110)#end
Verify that the port channels used in the VLT domain are assigned to the same VLAN.
