Cấu hình CoS trên Switch EX Series
CoS (Class of Service) giúp quản lý lưu lượng trên switch để bảo đảm các ứng dụng quan trọng khi mạng gặp tắc nghẽn và độ trễ. Bằng cách sử dụng CoS, bạn có thể phân loại lưu lượng thành các nhóm và cung cấp mức độ thông lượng (throughput) cũng như kiểm soát mất gói khác nhau. Điều này đặc biệt quan trọng đối với lưu lượng nhạy cảm với jitter và độ trễ, chẳng hạn như lưu lượng thoại (voice traffic).
Bài viết này hướng dẫn cách cấu hình CoS trên một switch EX Series đơn lẻ trong mạng.
Bài viết này sử dụng các thành phần phần cứng và phần mềm sau:
Bài viết này sử dụng mô hình mạng như hình 1.
Hình 1: Mô hình cấu hình CoS
Mô hình mạng cho cấu hình CoS
Mô hình mạng trong ví dụ này bao gồm các switch EX Series hoạt động tại lớp truy cập (access layer).
Các switch EX Series tại lớp truy cập được cấu hình để hỗ trợ phân chia VLAN. Cụ thể:
Bảng 1: Cấu hình VLAN

Hỗ trợ PoE trên các cổng của switch EX Series
Các cổng trên switch EX Series có khả năng cấp nguồn PoE (Power over Ethernet) để cung cấp cả kết nối mạng và nguồn điện cho các thiết bị VoIP. Điều này giúp các điện thoại IP VoIP có thể hoạt động mà không cần nguồn điện bên ngoài, giúp triển khai dễ dàng hơn.
Cấu hình cổng trên switch 48-port hỗ trợ PoE
Bảng 2 hiển thị các giao diện switch được gán vào các VLAN cũng như địa chỉ IP của các thiết bị kết nối trên switch 48 cổng, trong đó tất cả các cổng đều hỗ trợ PoE.
Bảng 2: Cấu hình cổng switch – VLAN và thiết bị trên switch PoE 48 cổng

**Lưu ý khi cấu hình CoS trên switch EX Series
Phạm vi của ví dụ này:
Ví dụ này hướng dẫn cấu hình CoS trên một switch EX Series độc lập. Nó không bao gồm các tình huống triển khai CoS trên toàn bộ mạng, nơi có thể cần các cấu hình khác nhau trên các switch đầu vào (ingress) và đầu ra (egress) để đảm bảo phân loại và xử lý lưu lượng một cách đồng bộ trên nhiều thiết bị mạng.
Cấu hình schedulers với ưu tiên cao nhất (strict-high priority):
Cấu hình CoS trên Switch EX Series
- Cấu hình nhanh bằng CLI (CLI Quick Configuration)
Để nhanh chóng cấu hình CoS trên switch EX Series, hãy sao chép và dán các lệnh sau vào terminal của switch:

Thống kê lưu lượng (Traffic statistics)
Trường Traffic statistics: trong kết quả đầu ra cho thấy lưu lượng egress (ra) khoảng 400 Mbps (345,934,816 bps).
Khi giới hạn băng thông cổng (Port Shaping) 100 Mbps được áp dụng cho giao diện ge-0/0/0, bạn sẽ thấy kết quả sau khi chạy lệnh:
