4 Using MLAG in Dell Networks . Executive Summary Multi-switch Link Aggregation or MLAG is a feature that allows two Dell Networking switches to act as a single switch, provides multiple paths across the network with benefits like:  Failover in cases of failed cables or switches  Increased bandwid...

5 Using MLAG in Dell Networks . 1 Introduction MLAGs provide an active-active split aggregation deployment across two switches acting as one. MLAG creates a more resilient network with higher bandwidth capabilities. This white paper discusses MLAGs, how and when they are used, caveats to look out fo...

6 Using MLAG in Dell Networks . 2 Caveats for Enabling MLAG There are a few limitations in implementing MLAGs:  Two identical switch models are required to create MLAG peers. This means an N2048 can only be peered with another N2048, an N3024 with another N3024, and so on.  Peer devices must use t...

It is also recommended for MLAG to be temporarily disabled in order to make subsequent changes to the above se...

8 Using MLAG in Dell Networks . 3 Supported Topologies MLAG topologies contain several options. They can be a single layer (only one pair of MLAG peer switches) or two layers (two pair of MLAG peer switches). The peer-link between peers can have anywhere from 1 to 8 active interfaces to create the l...

20 Using MLAG in Dell Networks . VLT is a feature similar to MLAG, but is available on the FTOS-based Dell Networking switches like the S4810. Each peer pair must use the same multi-chassis lag feature. This will provide the network with the same resiliency and improved bandwidth as when using MLAG ...
