7 Environment Two: Dell Networking switches with mVLT
and IOM in Full Switch mode
Full Switch mode is a new DNOS 9.10 feature that allows a network administrator to incorporate layer
3 functionality into a FN IOM environment. This new switch mode mirrors the same functionality as
Dell EMC’s award-winning MXL switching module, made for the M1000e chassis.
The Dell Blade I/O Manager view (Figure 28) below shows the FN IOM in Full Switch mode.

This section presents an example of Dell Networking S4810 and FN IOM switches working together
in a multi-Virtual Link Trunking (mVLT) configuration. mVLT represents Dell EMC’s standard
representation of multi-Virtual Link Trunking as presented in this document.
Figure 29 illustrates using Dell EMC’s VLT protocol on a pair of IOMs in a switch environment
connecting to two Dell Networking S4810s switches. In this mVLT configuration, multiple valid paths
exist which enable the environment to survive the failure of one S4810 switch and/or one IOM, and/or
one NIC interface per server. Because all paths are actively used, the result is a highly fault-tolerant
environment, which makes full use of the throughput capabilities of all switches.
