ОБЗОР ПРОДУКТА
Designed for the digital workplace, the Aruba 2540 Switch Series is optimized for today’s mobile and IoT needs. The переключатели are easy to deploy, использовать и управлять с помощью Aruba AirWave или Aruba Central.. Aruba ClearPass предлагает централизованную безопасность и поддержку внешнего портала авторизации.. Аруба 2540 Switch Series provides a convenient and cost-effective wired access solution that can be quickly set up with Zero Touch Provisioning. PoE+ models deliver power across all access ports for wireless APs, камеры видеонаблюдения, and other IoT devices. The 2540 has wire-speed backhaul bandwidth capacity with built-in 10 GbE uplinks, надежный QoS, static and RIP routing, IPv6 and includes a limited lifetime warranty with no software licensing required.

ENHANCED FEATURES
Программно-определяемые сети
• Supports REST APIs to enable automation of network operations, мониторинг, и устранение неполадок
Unified Wired and Wireless
• Supports unified wired and wireless policies using Aruba ClearPass Policy Manager • Switch auto-configuration automatically configures switches for different settings such as VLAN, CoS, PoE max power, и приоритет PoE при обнаружении точки доступа Aruba. • Роль пользователя определяет набор политик на основе коммутатора в таких областях, как безопасность., аутентификация, и качество обслуживания. Роль пользователя можно назначить группе пользователей или устройств., using switchbased local user role or download from ClearPass • Static IP Visibility allows ClearPass to do accounting for clients with static IP address
Quality of Service (качество обслуживания)
• Traffic prioritization (IEEE 802.1p) allows real-time traffic classification into eight priority levels mapped to eight queues • Layer 4 prioritization based on TCP/UDP port numbers • Class of service (CoS) sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Слой 3 протокол, TCP/UDP port number, source port, and DiffServ • Rate limiting sets per-port ingress enforced maximums and per-port, per-queue minimums • Large buffers provide graceful congestion management
Connectivity
• Flexible 10 Gbps Ethernet with four built-in 10 Gigabit ports (СФП+) • Auto-MDIX provides automatic adjustments for straight-through or crossover cables on all 10/100 и 10/100/1000 ports • IEEE 802.3at Power over Ethernet (PoE+) provides up to 30 W per port that allows support of the latest PoE+capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3afcompliant end device; eliminates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments • Pre-standard PoE support detects and provides power to pre-standard PoE devices • IPv6 -IPv6 host Enables switches to be managed in an IPv6 network -Dual stack (IPv4 and IPv6) Transitions from IPv4 to IPv6, supporting connectivity for both protocols -MLD snooping Forwards IPv6 multicast traffic to the appropriate interface -IPv6 ACL/QoS Supports ACL and QoS for IPv6 network traffic -IPv6 routing Supports static and RIPng protocols -Security Provides RA guard, DHCPv6 protection, dynamic IPv6 lockdown, and ND snooping
