Introduction to the Functional Modes of Aggregation Switches
Switching: Forwarding data packets based on their destination MAC addresses. VLAN Management: Segmenting the network into logical groups for security and performance. 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. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help. Switch aggregation is transforming how networks handle data traffic. However, the Fortinet recommended architecture remains the same for this wide range. 3ad link aggregation enables you to group Ethernet interfaces to form a single link layer interface, also known as a link aggregation group (LAG) or bundle.
