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 (RMON): Embedded RMON software agent supports one RMON group (statistics) for enhanced
- raffic 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.
- DHCP (Options 66 and 67) Dynamic Host Configuration Protocol (DHCP) options facilitate tighter control from a entral 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 (available April 2011)

- 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
- Jumbo frames Frame sizes up to 10 KB supported on 10/100 and Gigabit interfaces
- MAC table Up to 8000 MAC addresses
Discovery
- Link Layer Discovery Protocol (LLDP) (802.1ab) with LLDPMED extensions: LLDP 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 (available April 2011)
