Unauthorized access to an aggregation switch could result in a security breach, leading to data loss or system downtime. Scalability and high bandwidth are critical considerations when selecting an aggregation switch. They are literally 6x more expensive, unless you truly need more than 8 aggregation ports (why?) or 25Gb links, why waste all that money? It's like asking ”why do people recommend a Kia when you can just drive a Bentley?” Pro, cheap, 10GB, fully managed Con, L2 only, limited to 4 10GB rj45. An aggregate switch is a high-capacity network switch that consolidates connections from multiple access switches, acting as a central point for managing network traffic and providing enhanced bandwidth capabilities. Efficiency: Streamlined support, training, and upgrades. Integration: Improved compatibility with other tools. Link aggregation is sometimes called by other names: The most common device combinations involve connecting a switch to another switch, a server, a network attached storage (NAS). The technology known as Multi-Chassis Link Aggregation (MLAG) aggregates links among several physical switches to offer redundancy and high availability in contemporary networking topologies.
