What Is an Aggregation Switch?
An aggregation switch sits between access layer switches and the core network, acting as an intermediary. It collects traffic from multiple access switches, aggregates it, and then forwards
What are the typical configurations for an aggregation switch
Aggregation switches can be configured with link aggregation, VLANs, stacking, Layer 3 routing, DHCP, and redundancy protocols to optimize traffic flow and network reliability.Link AggregationAggregation switches support link aggregation to combine multiple physical ports into a single logical link, increasing bandwidth and providing redundancy. Options include:Static Aggregation (ON mode): Ports are manually grouped without negotiation. Up to 8 ports can be aggregated on some devices .Dynamic Aggregation (LACP): Uses the Link Aggregation Control Protocol (LACP) to negotiate aggregation with the remote device. Modes include active (initiates negotiation) and passive (responds to negotiation). Dynamic groups can include up to 12 ports, with some ports in backup state .Port Attributes: All aggregated ports must have consistent speed, duplex mode (full duplex), and link type (trunk, hybrid, or access) to ensure proper operation .VLAN and Layer 2/3 ConfigurationVLAN Assignment: Configure permitted VLANs and Port VLAN ID (PVID) for each port in the aggregation group .Layer 3 Interfaces: Aggregation switches can be configured with IP addresses and routing for Layer 3 interfaces to enable inter-VLAN routing and connectivity to core switches .DHCP Services: Aggregation switches can act as DHCP servers to assign IP addresses to wired and wireless clients .Stacking and RedundancyStacking: Aggregation switches can be stacked to increase interface density and provide device-level backup .Redundancy Protocols: Support for VRRP (Virtual Router Redundancy Protocol) and HSB (Hot Standby) ensures high availability for critical services .Failover: In link aggregation, if one member link fails, traffic continues over remaining links, maintaining connectivity .Load Balancing and Traffic ManagementLoad Balancing: Traffic is distributed across aggregated links to optimize bandwidth usage .Port Priority and System Priority: Some platforms allow configuration of port and system priorities to influence traffic distribution and failover behavior .Additional FeaturesSpanning Tree Protocol (STP): Must be consistently configured across aggregated ports, including STP enable/disable, priority, and cost .Interface Configuration: Supports trunk, hybrid, or access modes, and VLAN transparency can be configured to control which VLANs are forwarded .Direct Forwarding for Wireless: Aggregation switches can support direct forwarding modes for wireless APs, separating management and service VLANs . By combining these configuration options, aggregation switches provide high throughput, redundancy, and flexible traffic management, serving as a critical bridge between access and core layers in enterprise and campus networks .
