Parameters of a 24-Port Aggregation Switch

A 24-port aggregation switch typically supports static and dynamic port aggregation, PoE/PoE++ power, redundant uplinks, and advanced management features.

Port Aggregation Features

• Aggregation Modes: Supports static (ON mode) and dynamic (LACP Active/Passive) aggregation. Static groups can include up to 8 ports, while dynamic groups can have up to 12 ports, with 8 active and 4 backup ports for redundancy .
• LACP Support: Dynamic aggregation uses the Link Aggregation Control Protocol (802.3ad) to negotiate and maintain link consistency between switches .
• MC-LAG Option: Some switches support Multi-Chassis Link Aggregation (MC-LAG) for higher resilience, allowing two switches to operate as a single logical unit with load balancing and redundancy .
• Port Attributes: All aggregated ports must have consistent configurations, including STP settings, VLAN membership, port speed, duplex mode (full duplex only), and link type (trunk, hybrid, or access), .

Power and PoE Capabilities

• PoE/PoE++ Support: Many 24-port aggregation switches provide 802.3bt PoE++ (up to 90–95W per port) and PoH (Power over HD-BASE-T) modes .
• Total Power Budget: High-capacity switches can deliver up to 2,280W for powering multiple devices simultaneously .
• Redundant Power Supply: Dual modular power slots allow RPS (1+1) or EPS (2+0) modes, ensuring backup power or extended PoE capacity as needed .

Uplink and Connectivity

• Uplink Ports: 24-port switches often include 4 x 25Gb or higher-speed uplinks for aggregation to upstream Layer 3 switches or routers .
• Stacking: Some models support stacking via uplink ports to increase scalability and simplify management .
• MACsec Support: Line-rate 256-bit MACsec encryption may be available for secure connectivity to end devices and uplinks .

Management and Monitoring

• Management Interfaces: Web GUI, CLI, SNMP, and cloud-based platforms (e.g., ExtremeCloud IQ) for monitoring, configuration, and firmware updates .
• Network Health Monitoring: Real-time monitoring of port status, bandwidth usage, and alarms to ensure network reliability .
• Rate Limiting and Security: Port-based rate limiting, MAC filtering, and access control to protect network integrity .

Summary

A 24-port aggregation switch is designed for high-performance, resilient networks, offering flexible port aggregation, PoE/PoE++ support, redundant uplinks, and advanced management. Key parameters include aggregation mode (static/dynamic), LACP support, PoE power budget, uplink speed, redundancy options, and monitoring capabilities, making it suitable for enterprise, campus, and video surveillance networks .
