HP ProCurve 2800 Switch Series - Overview
Product description
Figure 1: HP ProCurve Switch 2824
|
Figure 2: HP ProCurve Switch 2848
|
| The HP ProCurve Switch 2800 Series consists of two switches: the 24-port HP ProCurve Switch 2824 with 20 10/100/1000
ports, and the 48-port HP ProCurve Switch 2848 with 44 10/100/1000 ports. In addition, each switch has four dual-personality
ports for RJ-45 10/100/1000 or mini-GBIC connectivity. The 2800 series is ideal for secure 10/100/1000 connectivity, and it
offers access security and advanced prioritization and traffic-monitoring capabilities. With support for IP static routing, the 2800
series is well-suited for environments that need basic routing at the edge of the network. |

| Connectivity
|
Dual-personality functionality:
Four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-
SX, -LX, or -LH
|
| Performance
|
48 Gbps backplane with up to 34.7 million pps (HP ProCurve 2824) and 96 Gbps backplane with up to 69.8 million
pps (HP ProCurve 2848): ten times the bandwidth for low-latency throughput |
| 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
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:
Provides uninterrupted power
|
| 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 packet support:
Supports up to 9,216 byte frame size to improve performance of large data transfers
|
| 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
|
Dynamic ARP protection:
Blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
Dynamic IP lockdown:
Works with DHCP protection to block traffic from unauthorized host, preventing IP source address
spoofing
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 method 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 the client's MAC address
Secure FTP:
Allows secure file transfer to/from the switch; protects against unwanted file downloads or unauthorized copying
of switch configuration file
RADIUS/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
|
IP multicast snooping and data-driven IGMP:
Automatically prevents flooding of IP multicast traffic
IEEE 802.1AB Link Layer Discovery Protocol (LLDP):
automated device discovery protocol for easy mapping by network
management applications
Per-port broadcast throttling:
Selectively configures broadcast control on heavy traffic port uplinks
|
| Quality of Service (QoS)
|
Traffic prioritization (IEEE 802.1p):
Allows real-time traffic classification into eight priority levels mapped to four 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, 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
Auto-MDIX:
Automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Dual flash images:
Provides independent primary and secondary operating system 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 HP 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
Multiple configuration files:
Multiple configuration files can be stored to the flash image
