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 bandwidth of up to double the bandwidth of a single switch

∙Elimination of port blocking as well as reconvergence delays of spanning tree

MLAGs are created by connecting a Dell Networking switch to another Dell Networking switch through Peer-Link ports to create MLAG peers (the two connected switches). Other switches directly connected to the MLAG peers are unaware that they are connecting to two switches. Two switches appear as a single switch on the network.

All links in the MLAG can carry data traffic across many physically diverse topologies. In the case of a link or switch failure, traffic continues to flow with minimal disruption. MLAG optimnizes availability and bandwidth between attached devices in Dell’s Datacenter and Campus networking solutions.

The following Dell Networking N-series switches support MLAG and may be used in building the configurations in this white paper:
