ARUBA 2540 SWITCH SERIES (JL357A)

PRODUCT OVERVIEW

Designed for the digital workplace, the Aruba 2540 Switch Series is optimized for today’s mobile and IoT needs. The switches are easy to deploy, use and manage using Aruba AirWave or Aruba Central. Aruba ClearPass offers centralized security and external captive portal support.

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, security cameras, and other IoT devices.

The 2540 has wire-speed backhaul bandwidth capacity with built-in 10 GbE uplinks, robust QoS, static and RIP routing, IPv6 and includes a limited lifetime warranty with no software licensing required.

ENHANCED FEATURES

Software-defined networks

• ● Supports REST APIs to enable automation of network operations, monitoring, and troubleshooting

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, and PoE priority when an Aruba access point is detected
• ● User Role defines a set of switch-based policies in areas such as security, authentication, and QoS. A user role can be assigned to a group of users or devices, using switchbased local user role or download from ClearPass
• ● Static IP Visibility allows ClearPass to do accounting for clients with static IP address

KEY FEATURES of JL357A

• ● Aruba Layer 2 switch series with static and RIP routing, ACLs, and robust QoS
• ● Security and network management via Aruba ClearPass Policy Manager, Aruba AirWave and Aruba Central
• ● Simple deployment with Zero Touch Provisioning
• ● Convenient 10 GbE uplinks and up to 370 W PoE+
• ● Software defined ready with REST APIs

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), Layer 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 and 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

Performance and Efficiency

• ● Energy-efficient design delivers power savings
  • ● 80 PLUS Silver Certified power supply increases efficiency and savings
  • ● Energy-efficient Ethernet (EEE) support reduces power consumption in accordance with IEEE 802.3az
• ● Designed with the latest ProVision ASIC, providing very low latency, increased packet buffering, and adaptive power consumption
• ● Selectable queue configurations allow for increased performance by selecting the number of queues and associated memory buffering that best meet the requirements of the network applications

Convergence

• ● IP multicast snooping and IGMP automatically prevent flooding of IP multicast traffic
• ● IEEE 802.1AB Link Layer Discovery Protocol (LLDP) facilitates easy mapping using network management applications with LLDP automated device discovery protocol
• ● LLDP-MED (Media Endpoint Discovery) defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN to configure automatically network devices such as IP phones
• ● PoE and PoE+ allocations support multiple methods (automatic, IEEE 802.3at dynamic, LLDP-MED fine grain, IEEE 802.3af device class, or user-specified) to allocate and manage PoE and PoE+ power for more efficient energy savings
• ● Local MAC Authentication assigns attributes such as VLAN and QoS using locally configured profile that can be a list of MAC prefixes

Resiliency and high availability

• ● IEEE 802.1s Multiple Spanning Tree provides high link availability by allowing multiple spanning trees; provides legacy support for IEEE 802.1d and IEEE 802.1w
• ● IEEE 802.3ad link-aggregation-control protocol (LACP) and port trunking support up to 26 static, dynamic, or distributed trunks with each trunk having up to eight links (ports) per static trunk
• ● SmartLink provides easy-to-configure link redundancy of active and standby links

Simplified Configuration and Management

• ● SNMPv1, v2, and v3 provide complete support of SNMP; support of industry-standard Management Information Base (MIB) plus private extensions; SNMPv3 supports increased security using encryption
• ● Zero-Touch Provisioning (ZTP) simplifies installation of the switch using Aruba Activate or a DHCP-based process with AirWave Network Management
• ● Flexible management JL357A with same hardware – Supports both cloud-based Central and on-premise AirWave without ripping and replacing switching infrastructure
• ● Aruba Central cloud-based management platform offers a simple, secure, and cost-effective way to manage switches

Manageability

• ● Dual flash images provide independent primary and secondary operating system files for backup while upgrading
• ● Friendly port names allow assignment of descriptive names to ports
• ● Find-Fix-Inform finds and fixes common network problems automatically, then informs administrator
• ● Multiple configuration files allow multiple configuration files to be stored to a flash image
• ● Software updates free downloads from the Web
• ● RMON, XRMON, and sFlow® provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
• ● Troubleshooting ingress and egress port monitoring enable more efficient problem solving
• ● Unidirectional link detection (UDLD) monitors the link between two switches and blocks the ports on both ends of the link if the link goes down at any point between the two devices
