S5500V2-EI comes with fixed 10GE and mixed Gigabit copper/fixed SFP ports to build non-blocking networks cost-effectively. Optional expansion slots accept various daughter cards including 40GE QSFP+, 10GE SFP+ and combo GE modules for flexible port scaling, protecting investment and cutting upgrade cost for core or aggregation deployment.

IRF2 virtualizes multiple physical switches into one logical device for unified administration:

Compatible with EAD and iMC system to integrate endpoint antivirus, patch management and access control into proactive full-network defense. It supports MAC/802.1X/Portal authentication plus binding of user account, IP, MAC, VLAN and port with dynamic policy delivery. Advanced VLAN-based ACL and uRPF defend against source IP spoofing; port isolation and secure MAC learning prevent intra-VLAN virus spread and unauthorized terminal access.

Hardware design includes hot-swappable AC/DC dual power supplies and redundant fans with temperature-based speed adjustment and fault alert. Rich link protection covers LACP, STP/RSTP/MSTP, Smart Link and RRPP; IRF2 1:N backup, ring stacking and cross-box link aggregation guarantee stable operation under heavy multi-service traffic.

L2~L4 traffic classification based on MAC, IP, TCP/UDP port, protocol and VLAN; SP/WRR/SP+WRR queue scheduling and bidirectional port mirroring for traffic monitoring and troubleshooting.

Equipped with Console, Micro USB and out-of-band Ethernet port; compliant with SNMPv1/v2/v3, iMC & OpenView. Administration options include CLI, Telnet, Web and SSH2.0 encryption. SPAN/RSPAN multi-port mirroring enables full traffic analysis to facilitate network optimization.
