  • Should core switches use stacking or mlag

    Should core switches use stacking or mlag

    Enterprise high availability (HA) strategies fall into three primary models: The correct choice depends on: If your downtime tolerance is less than 1 second, MLAG is generally superior. If operational simplicity is more important than fault isolation, stacking may be sufficient. MLAG vs stacking is frequently discussed in network architecture, as both enable multiple switches to function as a single logical device. While MLAG and switch stacking enhance redundancy, performance, and operational simplicity, their architectural differences can significantly impact network. MLAG is the ability of switches to appear as a single switch at layer 2, so that bundles of links in the form of LAGs can be diversely connected to each switch and appear as one. LAGs are typically created North & South i. Clients don't need to renegotiate if one member goes down, and management is simple because you only configure one device.
