With support for both static and RIP routing protocols, the JL357A Aruba IOT Ready 2540 48-Port PoE+ Gigabit Ethernet 4SFP+ Switch from HP is a versatile and reliable networking solution. This switch comes equipped with 48 autosensing Gigabit Ethernet PoE+ compliant 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. With PoE+ compliant network ports this switch is capable of powering a variety of PoE compliant devices such as access points, IP cameras, VoIP equipment and more; and with a PoE budget of 370 W this switch has the juice needed to power multiple devices.
Inside the Aruba JL357A 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 JL357A 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 JL357A 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.
Unified Wired and Wireless
Quality of Service (QoS)
- 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
- 80 PLUS Silver Certified power supply increases power efficiency and savings.
- Energy-efficient Ethernet (EEE) support Reduces power consumption in accordance with IEEE 802.3az
Resiliency and High Availability
Layer 2 Switching
Layer 3 Services
Layer 3 Routing
- IEEE 802.1X Uses an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server to authenticate in accordance with industry standards.
- 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
- 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
