93 PowerEdge FX2 – FN I/O Module – VLT Deployment Guide | Version 2.2
VLT Mode: An operational mode for an IOM that automatically configures VLT using external facing
port 9 as the VLTi, leaving the three remaining ports available for upstream connectivity.
VLT Peer Keepalive Link: A VLT peer keepalive link monitors the vitality of a VLT peer switch by
sending periodic keepalive messages between VLT peer devices. No data or synchronization traffic is
sent over this link, only keepalive messages.
VLT Peer-Link: See VLTi.
