Additional VLT Sample Congurations
To congure VLT, congure a backup link and interconnect trunk, create a VLT domain, congure 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 congurations.
Conguring 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
Congure the backup link.
Congure the VLT interconnect (VLTi).
Congure the port channel to an attached device.
Verify that the port channels used in the VLT domain are assigned to the same VLAN.
Conguring Virtual Link Trunking (VLT Peer 2)
Enable VLT and create a VLT domain with a backup-link VLT interconnect (VLTi).
Dell_VLTpeer2(conf)#vlt domain 999
Dell_VLTpeer2(conf-vlt-domain)#peer-link port-channel 100
Dell_VLTpeer2(conf-vlt-domain)#back-up destination 10.11.206.23
Dell_VLTpeer2(conf-vlt-domain)#exit
Congure the backup link.
Congure the VLT interconnect (VLTi).
Congure the port channel to an attached device.
Verify that the port channels used in the VLT domain are assigned to the same VLAN.
Verifying a Port-Channel Connection to a VLT Domain (From an Attached Access Switch)
On an access device, verify the port-channel connection to a VLT domain.
Troubleshooting VLT
To help troubleshoot dierent VLT issues that may occur, use the following information.
NOTE: For information on VLT Failure mode timing and its impact, contact your Dell Networking representative.
