Mô tả sản phẩm

Cisco Nexus 3548P-XL là switch Layer 2/3 hiệu năng cao dành cho trung tâm dữ liệu, trang bị 48 cổng SFP+ tốc độ 1/10Gbps với khả năng chuyển mạch 960 Gbps và tốc độ xử lý 720 triệu gói/giây. Thiết bị hỗ trợ cấu hình bộ nhớ lớn, tính năng jumbo frame, các giao thức định tuyến tiên tiến và công nghệ vPC, đáp ứng yêu cầu xử lý lưu lượng lớn với độ trễ cực thấp. Với nguồn đôi và quạt dự phòng hot-swappable, Cisco Nexus 3548P-XL đảm bảo độ tin cậy cao, dễ dàng bảo trì và tối ưu hiệu suất vận hành.

Đặc điểm nổi bật:

48 cổng SFP+ 1/10Gbps với throughput line-rate cho cả Layer 2 và Layer 3.
Băng thông chuyển mạch 960 Gbps, tốc độ xử lý 720 Mpps.
Nguồn đôi dự phòng và 4 quạt hot-swappable (3+1) cho độ tin cậy cao.
Hỗ trợ jumbo frames lên tới 9216 bytes, vPC, ECMP, và nhiều giao thức định tuyến (OSPF, BGP, EIGRP, RIPv2).
Bộ nhớ hệ thống 16 GB, bootflash 16 GB (phiên bản XL), bộ đệm 18 MB tối ưu xử lý lưu lượng.
Quản lý linh hoạt qua NX-OS, Python scripting, REST API, SNMP, RBAC, và Cisco DCNM.
