10 Gigabit connectivity: 24x 10-Multi-Gigabit Ethernet ports with 4x 10G SFPHigh-speed Uplink ports: 4 x 25G SFP28 ports for uplink connection and stackingScalability and high availability: Physical stacking up to 9 units and virtual stacking up to 32 unitsAdvanced L3 Features: OSPF, RIP/RIPng, IGMP v1/v2/v3, MLD v1/v2, QinQ, 802.1Qbb, RIP, OSPF, VRRP, 802.3ah, 802.1ag, Y.1731 OAMZero Touch Provisioning: Effortless deployment with zero touch provisioningEnhanced flow control mechanism: IEEE802.31Qbb Priority-based Flow Control (PFC) for intelligent lossless network and data center bridging World-class reliability The feature of advanced L2 and L3 functionalities like port security, Storm Control, Link Aggregation, and Spanning Tree Protocols. They include management options such as 802.3ah OAM, 802.1ag CFM, and industry-standard CLI support. With support for multiple images and configurations, the switches provide flexibility. The switches come equipped with x4 25G SFP28 uplink ports, supporting physical stacking for redundancy. They incorporate G.8032 Ethernet Ring Protection Switching (ERPS) to minimize recovery times to 50 ms. The addition of a USB 2.0 interface allows for storing config files, boot images, and syslog. For enhanced reliability, the switches support an optional external redundant power supply on all models, ensuring maximum uptime in critical environments. Comprehensive security Incorporating the latest security features such as Multi-layer and Packet Content Access Control Lists (ACL) and Storm Control, our switches provide robust protection. The exclusive D-Link Safeguard Engine is designed to prevent traffic flooding from malicious attacks, ensuring the uptime of your business network. Enhance user access control with IP-MAC-Port Binding, allowing you to bind a source IP address with its associated MAC and define the port number. Additionally, DHCP Snooping enables the switch to learn IP/MAC pairs by snooping DHCP packets and saving them to the IMPB whitelist, giving you extra control. Easy Access Control policies They feature multiple authentication mechanisms such as 802.1X, Web-based Access Control (WAC), and MAC-based Access Control (MAC) for strict access control and an easy deployment. After authentication, individual policies such as VLAN membership, Quality of Service (QoS) policies, and ACL rules can be assigned to each host.
