HP E4208-68G-4SFP vl Switch Switch 68 Ports Managed Rack Mountable

The Hp e4208-68g-4sfp vl procurve managed switch Dual flash images, provides independent primary and secondary operating system files for backup while upgrading. Friendly port names: allow assignment of descriptive names to ports. Multiple configuration files: allows a configuration file to be stored to a flash image. Sflow (rfc 3176): wire-speed traffic accounting and monitoring. Rmon and xrmon: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events. Resiliency and high availability, Hp e4208-68g-4sfp vl procurve managed switch has Ieee 802.3ad link aggregation control protocol (lacp) and hp port trunking: support up to 60 trunks, each with up to eight links (ports) per trunk. Ieee 802.1s multiple spanning tree protocol: provides high link availability in multiple vlan environments by allowing multiple spanning trees; encompasses ieee 802.1d spanning tree protocol and ieee 802.1w rapid spanning tree protocol. Hot-swappable modules: permit modules and mini-gbics to be added or swapped without interrupting the network. Optional redundant power supply: provides uninterrupted power; allows hot-swapping of one of the two supplies when installed. Management Uni-directional link detection (udld): monitors cable between two switches and shuts down the ports on both ends if the cable is broken, turning the bidirectional link into a unidirectional one; this prevents network problems such as loops Layer 2 switching Garp vlan registration protocol: allows automatic learning and dynamic assignment of vlans. Vlan support and tagging: supports ieee 802.1q (4,094 vlan ids) and 256 vlans simultaneously. Quality of service (qos) Layer 4 prioritization: enables 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. Traffic prioritization (ieee 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues.
