5 Using MLAG in Dell Networking N-Series Switches | version 1.5
Executive summary
Multi-switch link aggregation (MLAG) is a feature that allows two Dell Networking switches to act as a single
switch, providing multiple paths across the network and offering benefits such as:
• Failover in cases of defective cables or switches
• Double the bandwidth of a single switch
• Elimination of port blocking and re-convergence delays of spanning tree
Create an MLAG domain by connecting one Dell Networking switch to another through peer link ports. This
creates MLAG peers (the two connected switches). Other directly connected switches interact with the MLAG
peers as if the peers were a single network switch.
All links in the MLAG carry data traffic across physically diverse topologies. If a link or switch fails, traffic
continues to flow with minimal disruption. MLAG optimizes 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 guide:
N2024 N3024 N4032
N2024P N3024P N4032F
N2048 N3024F N4064
N2048P N3048 N4064F
N3048P
Note: Dell N15xx Series switches do not support MLAG.
