ENHANCED FEATURES
الشبكات المعرفة بالبرمجيات
• Supports REST APIs to enable automation of network operations, يراقب, واستكشاف الأخطاء وإصلاحها
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, كوس, PoE max power, وأولوية PoE عند اكتشاف نقطة وصول في Aruba • يحدد دور المستخدم مجموعة من السياسات القائمة على التبديل في مجالات مثل الأمان, المصادقة, وجودة الخدمة. يمكن تعيين دور المستخدم لمجموعة من المستخدمين أو الأجهزة, 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 (جودة الخدمة)
• 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 (كوس) sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), طبقة 3 protocol, 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 (SFP +) • Auto-MDIX provides automatic adjustments for straight-through or crossover cables on all 10/100 و 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
