Review the following examples of VLT configurations.

Configuring Virtual Link Trunking (VLT Peer 1)

Configure the backup link.

Dell_VLTpeer1(conf)#interface ManagementEthernet 0/0
                                 Dell_VLTpeer1(conf-if-ma-0/0)#
                                 ip address 10.11.206.23/
                                 Dell_VLTpeer1(conf-if-ma-0/0)#no shutdown
                                 Dell_VLTpeer1(conf-if-ma-0/0)#exit
                              

Configure the VLT interconnect (VLTi).

Dell_VLTpeer1(conf)#interface port-channel 100
                                 Dell_VLTpeer1(conf-if-po-100)#
                                 channel-member TenGigE 0/6,7
                                 Dell_VLTpeer1(conf-if-po-100)#no shutdown
                                 Dell_VLTpeer1(conf-if-po-100)#exit
                              

Enable VLT and create a VLT domain with a backup-link VLT 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 port channel to an attached device.

Dell_VLTpeer1(conf)#
                                 interface port-channel 110
                                 Dell_VLTpeer1(conf-if-po-110)#switchport
                                 Dell_VLTpeer1(conf-if-po-110)#channel-member TenGigE 0/5
