protects against unwanted file downloads or unauthorized copying of switch configuration file TACACS+: eases switch management security administration by using a password authentication server Source-port filtering: allows only specified ports to communicate with each other Secure Shell (SSHv2): encrypts all transmitted data for secure, remote command-line interface (CLI) access over IP networks Secure Sockets Layer (SSL): encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch Switch management logon security: can require either RADIUS or TACACS+ authentication for secure switch CLI logon Quality of Service (QoS) * Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into 8 priority levels mapped to 4 queues Class of Service (CoS): sets IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), L3 protocol, TCP/UDP port number, source port, and DiffServ Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers Manageability * RMON, XRMON, sFlow, and SMON: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events Friendly port names: allow assignment of descriptive names to ports ProCurve/IEEE Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports Dual flash images: provide independent primary and secondary OS files for backup while upgrading Software updates: free downloads from the Web Stacking capability: single IP address management for a virtual stack of up to 16 switches, including the ProCurve 2500 series, 2600 series, 2800 series, 3400cl series, 6108, 6400cl series, and 4100gl series Find-Fix-and-Inform: finds and fixes common network problems automatically, then informs administrator Troubleshooting: ingress/egress port monitoring enables network problem-solving Multiple configuration files: multiple config files can be stored to flash image Convergence * IP multicast snooping and data-driven IGMP: automatically prevents flooding of IP multicast traffic IEEE 802.1AB LLDP discovery: advertises and receives management information from adjacent devices on a network LLDP-MED (Media Endpoint Discovery): a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones Per-port broadcast throttling: selectively configure broadcast control on heavy traffic port uplinks Industry-leading warranty * Lifetime warranty: for as long as you own the product, with next-business-day advance replacement (available in most countries)
