H3C S6520X-SI series switches support M-LAG, which enables links of multiple switches to aggregate into one to implement device-level link backup. M-LAG is applicable to servers dual-homed to a pair of access devices for node redundancy. Streamlined topology: M-LAG simplifies the network topology and spanning tree configuration by virtualizing two. The switch offers high-density 10GE forwarding and can expand 10GE ports flexibly, working at wire-speed. It provides 16/24*10/1GE autosensing SFP+ ports, one expansion slot that support up to 10 kinds of modules range from GE to 10GE, 25GE, 40GE, and multi-giga ports. S6520X-26MC-UPWR-SI support 24 *1G/2.5G/5GBase-T (UPOE) ports, Max 90W PoE suppo. H3C Intelligent Resilient Framework 2 (IRF 2) virtualizes multiple S6520X-SI switches into one virtual switch and provides the following benefits: Scalability: IRF 2 allows you to add devices to the IRF 2 system easily. It provides a single point of management, enables switch plug-and-play, and supports software auto-update for software synchroniza. The switch offers a wide range of features, including: Modular hardware and software design:The switch uses modular, hot swapping, and redundancy design for hardware, including power modules and fan trays. The switch also uses modular design for software, which enables feature installation and removal on an as-needed basis. Refined physical archite. The switch supports AAA authentications (including RADIUS authentication) and dynamic or static binding of user identifiers such as user account, IP address, MAC address, VLAN, and port number. Using the switch in conjunction with H3C IMC, you can manage and monitor online users in real time and take prompt action on illegitimate behaviors. The Use.
