ENHANCED FEATURES
Redes definidas por software
• Supports REST APIs to enable automation of network operations, supervisión, y solución de problemas
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, y prioridad PoE cuando se detecta un punto de acceso de Aruba. • La función de usuario define un conjunto de políticas basadas en conmutadores en áreas como la seguridad., autenticación, y calidad de servicio. Se puede asignar una función de usuario a un grupo de usuarios o dispositivos., 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 (QoS)
• 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), Capa 3 protocolo, 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 Puertos gigabit (SFP+) • Auto-MDIX provides automatic adjustments for straight-through or crossover cables on all 10/100 y 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
