PRÉSENTATION DU PRODUIT
Designed for the digital workplace, the Aruba 2540 Switch Series is optimized for today’s mobile and IoT needs. Le commutateurs are easy to deploy, utiliser et gérer à l'aide d'Aruba AirWave ou d'Aruba Central. Aruba ClearPass offre une sécurité centralisée et une prise en charge de portail captif externe. The Aruba 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, des caméras de sécurité, and other IoT devices. Le 2540 has wire-speed backhaul bandwidth capacity with built-in 10 GbE uplinks, QoS robuste, static and RIP routing, IPv6 and includes a limited lifetime warranty with no software licensing required.

ENHANCED FEATURES
Réseaux définis par logiciel
• Supports REST APIs to enable automation of network operations, surveillance, et dépannage
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, et priorité PoE lorsqu'un point d'accès Aruba est détecté. • Le rôle utilisateur définit un ensemble de politiques basées sur le commutateur dans des domaines tels que la sécurité., authentification, et QoS. Un rôle d'utilisateur peut être attribué à un groupe d'utilisateurs ou d'appareils, 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), Couche 3 protocole, 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 et 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
