Connectivity
-
Dual-personality functionality:
four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
-
Auto-MDIX:
automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Performance
-
88 Gbps backplane with 64 million pps (ProCurve 3400cl-24G) and 136 Gbps backplane with 99.5 million pps (ProCurve 3400cl-48G):
up to ten times the bandwidth for low-latency throughput
-
Selectable queuing configurations:
increase performance by selecting the queuing configuration that best meets the requirements of network applications
-
Jumbo frames:
on Gigabit and 10-Gigabit ports, allow high-performance remote backup and disaster-recovery services (up to 4 ports per module on Gigabit modules)
Resiliency and high availability
-
Router redundancy (XRRP):
allows groups of two routers to dynamically back each other up to create highly available routed environments
-
IEEE 802.3ad Link Aggregation Control Protocol (LACP) and ProCurve trunking:
support up to 25 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
-
IEEE 802.1w Rapid Convergence Spanning Tree Protocol:
increases network uptime through faster recovery from failed links
-
Optional redundant power supply:
provides uninterrupted power (provided by ProCurve 600 RPS/EPS)
Layer 2 switching
-
ProCurve switch meshing:
dynamically load-balances across multiple active redundant links to increase available aggregate bandwidth
-
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
-
IEEE 802.1v protocol VLANs:
isolate select non-IPv4 protocols automatically into their own VLANs
Layer 3 routing
-
Layer 3 IP routing:
provides routing of IP at media speed; supports static routes, RIP, RIPv2, and OSPF
Security
-
Access control lists (ACLs):
provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number
-
Dynamic ARP protection:
blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
-
Port security:
allows access only to specified MAC addresses, which can be learned or specified by the administrator
-
Source-port filtering:
allows only specified ports to communicate with each other
-
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
-
IEEE 802.1X:
industry-standard way of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server
-
MAC address lockout:
prevents configured particular MAC addresses from connecting to the network
-
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
-
Secure FTP:
allows secure file transfer to/from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file
-
Secure management access:
all access methods--CLI, GUI, or MIB--are securely encrypted through SSHv2, SSL, and/or SNMPv3
Convergence
-
IP multicast routing (PIM Dense):
routes IP multicast traffic using the PIM Dense routing protocol
-
IP multicast snooping and data-driven IGMP:
automatically prevents flooding of IP multicast traffic
Quality of Service (QoS)
-
Rate limiting:
per-port ingress enforced maximums
-
Layer 4 prioritization:
enables prioritization based on TCP/UDP port numbers
-
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
Manageability
-
sFlow (RFC 3176):
wire-speed traffic accounting and monitoring
-
RMON, XRMON, and SMON:
provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
-
Find-Fix-and-Inform:
finds and fixes common network problems automatically, then informs administrator
-
Dual flash images:
provides independent primary and secondary OS files for backup while upgrading
-
Friendly port names:
allow assignment of descriptive names to ports
-
IEEE 802.1AB Link Layer Discovery Protocol (LLDP):
automated device discovery protocol for easy mapping by network management applications
-
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
