Management
Port mirroring: enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
sFlow (RFC 3176): provides scalable, ASIC-based, wire-speed network monitoring and accounting with no impact on network performance; this allows network operators to gather a variety of sophisticated network statistics and information for capacity planning and real-time network monitoring purposes
IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol for easy mapping by network management applications
RMON and XRMON: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
Command authorization: leverages RADIUS to link a custom list of CLI commands to individual network administrator's login; also provides an audit trail
Friendly port names: allow assignment of descriptive names to ports
Dual flash images: provides independent primary and secondary OS files for backup while upgrading
Find-Fix-and-Inform: finds and fixes common network problems automatically, then informs administrator
Uni-Directional Link Detection (UDLD): monitors a 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
Connectivity
IPv6: NEW!
IPv6 Host the switches can be managed and deployed at the edge of IPv6 networks
Dual Stack (IPv4/IPv6) provides transition mechanism from IPv4 to IPv6; supports connectivity for both protocols
MLD Snooping forwards IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from flooding the network
Plug-n-Play 10-Gbps Ethernet for stacking and uplink: four integrated 10-GbE ports (two CX4 and two X2) built-in on the switch
Dual-personality functionality: four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
Stacking capability: single IP address management for a virtual stack of up to 16 switches, including the ProCurve 2500 series, 2510 series, 2600 series, 2800 series, 2810 series, 2900 series, 3400cl series, 3500yl series, 4200vl series, 6108, 6200yl-24G-mGBIC, and 6400cl series
Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Performance
High-performance architecture: 115 Gbps switching fabric with up to 74 million pps (Switch 2900-24G) and 173 Gbps switching fabric with up to 110 million pps (Switch 2900-48G)
Selectable queue configurations: increase performance by selecting the number of queues and associated memory buffering that best meet the requirements of your network applications
Resiliency and high availability
IEEE 802.3ad Link Aggregation Protocol (LACP) and ProCurve trunking: support up to 24 trunks, each with up to 8 links (ports) per trunk
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
Layer 2 switching
VLAN support and tagging: supports the IEEE 802.1Q (4,096 VLAN IDs) and 256 VLANs simultaneously
GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
Jumbo frames: on Gigabit and 10-Gigabit ports, allow high-performance remote backup and disaster-recovery services
Layer 3 routing
Static IP routing: provides manually configured routing
RIP: provides RIPv1 and RIPv2 routing at media speed
Security
USB Secure Autorun (requires ProCurve Manager Plus): deploys, diagnoses, and updates switch using USB flash drive; works with secure credential to prevent tampering NEW!
Port security: allows access only to specified MAC addresses, which can be learned or specified by the administrator
MAC address lockout: prevents configured particular MAC addresses from connecting to the network
Multiple user authentication methods:
IEEE 802.1X industry-standard way of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server
Web-based authentication authenticates from Web browser for clients that do not support 802.1X supplicant; customized remediation can be processed on an external Web server
MAC-based authentication client is authenticated with the RADIUS server based on client's MAC address
Authentication flexibility:
Multiple IEEE 802.1X users per port provides authentication of up to 8 IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication
Concurrent IEEE 802.1X and Web or MAC authentication schemes per port switch port will accept any of IEEE 802.1X and either Web or MAC authentications
BPDU port protection: blocks Bridge Protocol Data Units (BPDU) on ports that do not require BPDUs, preventing forged BPDU attacks
Source-port filtering: allows only specified ports to communicate with each other
Secure FTP: allows secure file transfer to/from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file
TACACS+: eases switch management security administration by using a password authentication server
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
Custom banner: displays security policy when users log in to the switch
Convergence
IP multicast snooping (data-driven IGMP): automatically prevents flooding of IP multicast traffic
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
Software updates: free downloads from the Web
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 the 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
