Features
Features
Connectivity:
Jumbo packet support: supports up to 9, 216 byte frame size to improve performance of large data transfers
Resiliency and high availability:
IEEE 802.3ad Link Aggregation Control Protocol ( LACP) : provides link-level redundancy with support for up to 4 trunks on the ProCurve Switch 1800-8G and 12 trunks on the ProCurve Switch 1800-24G, each with up to 8 links ( ports) per trunk
Layer 2 switching:
VLAN support and tagging: support up to 64 port-based VLANs and dynamic configuration of IEEE 802.1Q VLAN tagging, providing security between workgroups
Quality of Service ( QoS) :
Traffic prioritization: honors priority of traffic based on 802.1p to deliver data to devices based on the priority and type of traffic
Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network
Manageability:
Intuitive Web interface: enables simple management via an easy-to-use Web browser interface for switch configuration, monitoring, and administration
Integration with ProCurve Manager: enables discovery and mapping via ProCurve Manager, available as a free download from the Web
IEEE 802.1AB Link Layer Discovery Protocol ( LLDP) : automated device discovery protocol for easy mapping by network management applications
Monitor and diagnostics:
Port mirroring: enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
Ease of use:
Comprehensive LED display with per-port indicators: provides an at-a-glance view of status, activity, speed, and full-duplex operation
ProCurve/ IEEE Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/ 100/ 1000 ports
Flexibility:
Small form factor: ideal for desktop use; space-efficient for deployment flexibility ( 1800-8G only)
Designed with no fan: enables quiet operation for deployment in open spaces
