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 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.

Discovery • Link Layer Discovery Protocol (LLDP) (802.1ab) with LLDP-MED 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

• Bonjour - The switch advertises itself using the Bonjour protocol.
