Connectivity
-
Dual-personality functionality: two 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
-
Power over Ethernet (IEEE 802.3af) compliant (ProCurve 2650-PWR, ProCurve 2626-PWR, ProCurve 2600-8-PWR): provides up to 15.4 W per port to power IP phones, wireless access points, Web cameras, and more (ProCurve 2650-PWR may require an external power supply to provide full 15.4 W for all 48 PoE-ready ports)
Performance
-
13.6 Gbps (ProCurve 2650 and 2650-PWR)/9.6 Gbps (ProCurve 2626, 2626-PWR, 2600-8-PWR) backplane: wire-speed non-blocking architecture for low-latency throughput
Resiliency and high availability
-
IEEE 802.3ad Link Aggregation Control Protocol (LACP) and ProCurve trunking: support for up to 6 trunks, each with up to 8 links (ports) per trunk; trunking across modules is supported
-
Spanning Tree Protocol (IEEE 802.1D): provides redundant links while preventing network loops
-
IEEE 802.1w Rapid Convergence Spanning Tree Protocol: increases network uptime through faster recovery from failed links
-
IEEE 802.1s Multiple Spanning Tree: provides high link availability in multiple VLAN environments by allowing multiple spanning trees
-
Optional external redundant power supply (ProCurve 2650-PWR, ProCurve 2626-PWR, ProCurve 2600-8-PWR): provides uninterrupted power; sold as an accessory
Layer 2 switching
-
VLAN support and tagging: support complete IEEE 802.1Q (4,096 VLAN IDs) and 253 VLANs simultaneously
-
GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
Layer 3 routing
-
Basic IP routing: enables automatic routing to the connected VLANs and up to 16 static routes--including one default route--in IP networks
Security
-
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
-
Dynamic IP lockdown: works with DHCP protection to block traffic from unauthorized host, preventing IP source address spoofing
-
Dynamic ARP protection: blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
-
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 similar to IEEE 802.1X, provides a browser-based environment to authenticate clients that do not support the IEEE 802.1X supplicant
-
MAC-based authentication client is authenticated with the RADIUS server based on client's MAC address
-
Authentication flexibility: NEW!
-
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
-
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
-
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
Convergence
-
IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol for easy mapping by network management applications
-
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
Quality of Service (QoS)
-
Traffic prioritization (IEEE 802.1p): allows real-time ProCurve Switch 2600 series 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
Manageability
-
RMON: provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events
-
Friendly port names: allow assignment of descriptive names to ports
-
Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
-
Dual flash images: provides independent primary and secondary OS files for backup while upgrading
-
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
-
Find-Fix-and-Inform: finds and fixes common network problems automatically, then informs administrator
-
Troubleshooting: ingress/egress port monitoring enables network problem-solving (ProCurve Switch 2626 and 2626-PWR only)
-
