C9800-L-C-K9 hỗ trợ những chuẩn xác thực và bảo mật nào cho mạng Wi-Fi doanh nghiệp?
C9800-L-C-K9 hỗ trợ Performance License, cho phép nâng cấp khả năng xử lý từ 250 lên 500 Access Point, từ 5.000 lên 10.000 Wireless Client và tăng thông lượng từ 5 Gbps lên 10 Gbps mà không cần thay thế thiết bị. Điều này giúp doanh nghiệp dễ dàng mở rộng hệ thống khi nhu cầu phát triển.
C9800-L-C-K9 có thiết kế vật lý như thế nào để tối ưu không gian lắp đặt?
C9800-L-C-K9 sở hữu thiết kế 1RU half-width chassis, chỉ chiếm một nửa chiều rộng của tủ rack 19 inch. Hai thiết bị có thể được lắp đặt cạnh nhau trên cùng một không gian 1RU, giúp tiết kiệm diện tích tủ rack và tối ưu hạ tầng trong các phòng máy hoặc trung tâm dữ liệu.
C9800-L-C-K9 có thể mở rộng hiệu năng bằng cách nào mà không cần thay đổi phần cứng?
C9800-L-C-K9 hỗ trợ các chuẩn bảo mật như WPA, WPA2, WPA3, IEEE 802.1X, MACsec, IPsec, DTLS và TLS 1.2, đồng thời tích hợp các giao thức xác thực RADIUS, TACACS+ và EAP. Các tính năng này giúp tăng cường bảo mật, kiểm soát truy cập và bảo vệ dữ liệu trên mạng không dây doanh nghiệp.
