Management
Web User Interface: Built-in switch configuration utility for easy browser-based device configuration (HTTP) Supports configuration, system dashboard, system maintenance and monitoring
Remote Monitoring: Embedded RMON software agent supports one RMON group (statistics) for enhanced traffic management, monitoring and analysis
IPv4 and IPv6 Dual Stack: Coexistence of both protocol stacks to ease migration
Firmware Upgrade: Web browser upgrade (HTTP) and TFTP
Port Mirroring: Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe Up to 4 source ports can be mirrored to one destination port. A single session is supported
VLAN Mirroring: Traffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe Up to 4 source VLANs can be mirrored to one destination port. A single session is supported
Dynamic Host Configuration Protocol (Options 66 and 67): Dynamic Host Configuration Protocol options facilitate tighter control from a central point (DHCP server) to obtain IP address, auto-configuration (with configuration file download)
Text-Editable Config Files: Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment
Smartports: Simplified configuration of QoS and security capabilities
Cloud Services: Support for FindIT Network Discovery Utility
Localization: Localization of GUI and documentation into multiple languages
Other Management: HTTP, RADIUS, port mirroring, TFTP upgrade, DHCP client, BOOTP, SNTP, ping, syslog
Power Efficiency
Energy Detect: Automatically turns off power on Gigabit Ethernet RJ-45 port when the switch detects a link down
Active mode is resumed without loss of any packets when the switch detects the link is back up
Cable Length Detection: Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter than 10 m
General Features
Jumbo Frames: Frame sizes up to 10 KB supported on Gigabit interfaces
MAC Table: Up to 8000 MAC addresses
Discovery
Link Layer Discovery Protocol (802.1ab) with LLDP-MED Extensions: Link Layer Discovery Protocol allows the switch to advertise its identification, configuration and capabilities to neighboring devices, which store the data in an MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones
Cisco Discovery Protocol: The switch advertises itself using the Cisco Discovery Protocol
