Connectivity
a.. Dual-personality functionality: two 10/100/1000 ports or mini-GBIC
slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
Performance
a.. 13.6 Gbps (HP ProCurve 2650 )/9.6 Gbps (HP ProCurve 2626 ) backplane:
wire-speed non-blocking architecture for low-latency throughput
Resiliency and high availability
a.. IEEE 802.3ad Link Aggregation Control Protocol (LACP) and ProCurve
trunking: support for up to six trunks, each with up to eight links (ports)
per trunk; trunking across modules is supported
b.. Spanning Tree Protocol (IEEE 802.1D): provides redundant links while
preventing network loops
c.. IEEE 802.1w Rapid Convergence Spanning Tree Protocol: increases
network uptime through faster recovery from failed links
d.. IEEE 802.1s Multiple Spanning Tree: provides high link availability in
multiple VLAN environments by allowing multiple spanning trees
Manageability
a.. RMON: provides advanced monitoring and reporting capabilities for
statistics, history, alarms, and events
b.. Friendly port names: allow assignment of descriptive names to ports
c.. Auto-MDIX: automatically adjusts for straight-through or crossover
cables on all 10/100 and 10/100/1000 ports
d.. Dual flash images: provides independent primary and secondary
operating system files for backup while upgrading
e.. Stacking capability: single IP address management for a virtual stack
of up to 16 switches, including the HP ProCurve Switch 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
f.. Find-Fix-Inform: finds and fixes common network problems
automatically, then informs administrator
g.. Troubleshooting: ingress/egress port monitoring enables network
problem-solving (HP ProCurve Switch 2626 and 2626-PWR only)
h.. Software updates: free downloads from the Web
Layer 2 switching
a.. VLAN support and tagging: support complete IEEE 802.1Q (4,096 VLAN
IDs) and 253 VLANs simultaneously
b.. GARP VLAN Registration Protocol: allows automatic learning and dynamic
assignment of VLANs
Layer 3 routing
a.. Basic IP routing: enables automatic routing to the connected VLANs and
up to 16 static routes--including one default route--in IP networks
Security
a.. Port security: allows access only to specified MAC addresses, which
can be learned or specified by the administrator
b.. MAC address lockout: prevents particular configured MAC addresses from
connecting to the network
c.. Dynamic IP lockdown: works with DHCP protection to block traffic from
unauthorized hosts, preventing IP source address spoofing
d.. Dynamic ARP protection: blocks ARP broadcasts from unauthorized hosts,
preventing eavesdropping or theft of network data
e.. Multiple user authentication methods:
a.. IEEE 802.1X: industry-standard method of user authentication using
an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server
b.. Web-based authentication: similar to IEEE 802.1X, it provides a
browser-based environment to authenticate clients that do not support the
IEEE 802.1X supplicant
c.. MAC-based authentication: client is authenticated with the RADIUS
server based on the client's MAC address
f.. Authentication flexibility: New!
a.. Multiple IEEE 802.1X users per port: provides authentication of up
to eight IEEE 802.1X users per port; prevents user "piggybacking" on another
user's IEEE 802.1X authentication
g.. Secure FTP: allows secure file transfer to and from the switch;
protects against unwanted file downloads or unauthorized copying of switch
configuration file
h.. RADIUS/TACACS+: eases switch management security administration by
using a password authentication server
i.. Source-port filtering: allows only specified ports to communicate with
each other
j.. Secure Shell (SSHv2): encrypts all transmitted data for secure, remote
command-line interface (CLI) access over IP networks
k.. Secure Sockets Layer (SSL): encrypts all HTTP traffic, allowing secure
access to the browser-based management GUI in the switch
l.. Switch management logon security: can require either RADIUS or TACACS+
authentication for secure switch CLI logon
Convergence
a.. IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device
discovery protocol for easy mapping by network management applications
b.. 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)
a.. Traffic prioritization (IEEE 802.1p): allows real-time HP ProCurve
Switch 2600 Series traffic classification into eight priority levels mapped
to four queues
b.. 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
c.. Layer 4 prioritization: enables prioritization based on TCP/UDP port
numbers
