This item is Brand New with Minor Box Damage
Just like you get in any retail store. Never used, factory sealed, comes with all accessories. Also with minor box damage.




With support for both static and RIP routing protocols, the JL355A Aruba IOT Ready 2540 48-Port Gigabit Ethernet 4SFP+ Switch from HP is a versatile and reliable networking solution. This switch comes equipped with 48 autosensing Gigabit Ethernet ports along with a single dual-personality serial console port that can be configured as either a RJ-45 port or micro-B USB port. Inside the Aruba JL354A you will find a 1016 MHz dual core ARM Cortex A9 CPU along with 1GB of DDR3 SDRAM and a 12.38 MB packet buffer to ensure smooth operation when the switch is operating at maximum capacity. The JL355A is capable of handling a heavy workload as it features a 176 Gbps switching capacity, a throughput of up to 112.0 Mpps, and a MAC address table capable of supporting up to 16,384 entries.

Once installed, users benefit from a variety of network features covering everything from wired and wireless connectivity to Quality of Service, connectivity, network management and more. This HP Aruba switch features the ClearPass Policy Manager support designed for use with both wired and wireless policies making it easy to manage connections to a variety of devices. Intuitive QoS functionality includes support for the 802.1p network standard to prioritize network traffic, support for Layer 4 prioritization, rate limiting on a per-port basis, and more. Connectivity features include auto-MDIX support, IPv6 compatibility, and more. Managing the network has also been simplified as the JL354A offers support for the SNMP v1, v2, and v3, zero touch provisioning, the option to utilize dual flash images, troubleshooting ingress, and more.

To secure the network HP has included a variety of security features in this Aruba switch. Multiple user authentication methods allow for a variety of avenues for users to access the network including a browser based method, MAC-based authentication, and 802.1X authentication. Other security features include access control lists, source-port filtering, secure shell encryption, port security, and more.

* Aruba ProVision ASIC architecture is designed with the latest Aruba 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 data-driven 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
* 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 in multiple VLAN environments 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


Management:

* SNMPv1, v2, and v3 provide complete support of SNMP; provide full 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 infrastructure using the Aruba Activate-based or a DHCP-based process with AirWave Network Management
* Aruba Central support 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 network 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


Layer 2 Switching:

* VLAN support and tagging supports IEEE 802.1Q (4,094 VLAN IDs) and 512 VLANs simultaneously
* Jumbo packet support improves the performance of large data transfers; supports frame size of up to 9,220 bytes
* IEEE 802.1v protocol VLANs isolate select non-IPv4 protocols automatically into their own VLANs
* Rapid per-VLAN spanning tree (RPVST+) allows each VLAN to build a separate spanning tree to improve link bandwidth usage; is compatible with PVST+

* - Web-based authentication provides a browser-based environment, similar to IEEE 802.1X, to authenticate clients that do not support the IEEE 802.1X supplicant.
* - MAC-based authentication authenticates the client with the RADIUS server based on the client's MAC address
* Authentication flexibility:
* - Multiple IEEE 802.1X users per port provides authentication of multiple IEEE 802.1X users per port; prevents a user from piggybacking on another user's IEEE 802.1X authentication.
* - Concurrent IEEE 802.1X, Web, and MAC authentication schemes per port switch port will accept up to 32 sessions of IEEE 802.1X, Web, and MAC authentications
* Access control lists (ACLs) provide IP Layer 3 filtering based on source and destination IP address or subnet and source and destination TCP/UDP port number
* Source-port filtering allows only specified ports to communicate with each other
* RADIUS/TACACS+ eases switch management security administration by using a password authentication server
