48 Gbps backplane with up to 35.7 mpps (Switch 2824) and 96 Gbps backplane with up to 71.4 mpps (Switch 2848): ten times the bandwidth for low-latency throughput
Dual-personality functionality: four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
Basic IP routing: enables automatic routing with up to 16 external routes-including one default route-in IP networks
IP multicast (data-driven IGMPv3): automatically prevents flooding of IP multicast traffic
802.3ad Link Aggregation Protocol (LACP) and HP trunking: support up to 24 trunks, each with up to 8 links (ports) per trunk; trunking across modules is supported
Optional external redundant power supply: provides uninterrupted power; sold as an accessory
RMON, XRMON, and SMON: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
Port security: prevents unauthorized access using MAC address lockdown
TACACS+: eases switch management security administration by using a password authentication server
Secure Shell (SSHv2): encrypts all transmitted data for secure remote access over IP networks
Secure Sockets Layer (SSL): encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
VLAN support and tagging: support complete 802.1Q (4,096 VLAN IDs) and 256 VLANs simultaneously
Traffic prioritization (802.1p): allows real-time traffic classification into 8 priority levels mapped to 4 queues
Per-port broadcast throttling: selectively configure broadcast control on heavy traffic port uplinks
Stacking capability: single IP address management for a virtual stack of up to 16 switches, including the 2500 series, 2600 series, 2800 series, 4000m, 6108, 8000m, and 4100gl series
HP Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Source port filters: allows only specified ports to communicate with each other
Troubleshooting: ingress/egress port monitoring enables network problem solving
