Virtual Link Trunking (VLT) | 969
• If the source is connected to an orphan (non-spanned, non-VLT) port in a VLT peer, the receiver is
connected to a VLT (spanned) port-channel, and the VLT port-channel link between the VLT peer
connected to the source and TOR is down, traffic is duplicated due to route inconsistency between
peers. To avoid this scenario, Dell Networking recommends configuring both the source and the
receiver on a spanned VLT VLAN.
