ENHANCED FEATURES
Redes definidas por software
• Supports REST APIs to enable automation of network operations, monitoramento, e solução 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, e prioridade PoE quando um ponto de acesso Aruba é detectado • A função do usuário define um conjunto de políticas baseadas em switch em áreas como segurança, autenticação, e QoS. Uma função de usuário pode ser atribuída a um grupo de usuários ou dispositivos, using switchbased local user role or download from ClearPass • Static IP Visibility allows ClearPass to do accounting for clients with static IP address
Qualidade de serviço (QoS)
• Priorização de tráfego (IEEE802.1p) 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) define a etiqueta de prioridade IEEE 802.1p com base no endereço IP, Tipo de serviço IP (Termos de Serviço), Camada 3 protocolo, Número da porta TCP/UDP, porta de origem, 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 (SFP+) • Auto-MDIX provides automatic adjustments for straight-through or crossover cables on all 10/100 e 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
