1、 Quick overview of core parameters
Model attribute: Extreme 220-48P-10GE4 is a mid-range 1U rack mounted full gigabit PoE+managed switch under Extreme Networks, focusing on small and medium-sized enterprise aggregation layer and high-end access layer networking. "48P" represents 48 PoE+ports, and "10GE4" represents 4 10G SFP+10 Gigabit uplink ports. Compared with the 210 series, it upgrades the uplink speed and balances high-density power supply and high-speed backhaul.
Port configuration: 48 10/100/1000Base TX PoE+electrical ports (supporting IEEE 802.3af/at, maximum 30W per port)+4 10G Base-X SFP+optical ports (10 Gigabit uplink), electrical ports support rate adaptation, optical ports are compatible with 10 Gigabit multimode/single-mode SFP+modules, suitable for high-speed fiber uplink scenarios.
Key performance: Switching capacity of 192Gbps, packet forwarding rate of 143Mpps, total PoE power of 370W (typical value), support for jumbo frames (maximum 9216 bytes), MAC address table capacity of 32K, meeting the full power supply of 48 PoE terminals, and solving the bottleneck of gigabit backhaul through 10G uplink.
2、 Core functions and values
10 Gigabit uplink breakthrough: 4 SFP+10 Gigabit uplink ports, single port speed up to 10Gbps, 10 times higher than traditional gigabit uplink bandwidth, suitable for high traffic scenarios such as 4K/8K surveillance video, big data backup, cloud application access, etc., avoiding uplink congestion.
PoE+Power Supply Continuation: Single port 30W output, can simultaneously supply power to Wi Fi 6/6E wireless APs, high-definition IP cameras, and smart conference terminals, reducing power wiring costs. Supports "port timed power supply" function, can start and stop terminal devices as needed, reducing energy consumption.
Advanced management capabilities: Supports Web UI, CLI, and ExtremeCloud IQ standard version platform, enabling batch configuration of multiple devices, visual analysis of traffic (such as real-time monitoring of bandwidth usage of each port), compatible with "zero touch deployment", automatically synchronizes configuration after new devices are powered on, simplifying operation and maintenance.
Security and reliability upgrade: In addition to basic protections such as 802.1X and ACL, "Dynamic ARP Detection (DAI)" has been added to prevent ARP spoofing attacks; Support MSTP multi spanning tree protocol, which can plan forwarding paths according to VLANs and improve network link utilization; Support dual power redundancy (some versions) to ensure uninterrupted operation of equipment.
