Data Sheet
Feature Description
Auto Smartports Applies the intelligence delivered through the Smartport roles and applies it automatically to the
port based on the devices discovered over CDP or LLDP-MED. This facilitates zero touch
deployments.
Textview CLI Scriptable command-line interface. A full CLI as well as a menu-based CLI is supported
Cloud services Support for Cisco Small Business FindIT Network Discovery Utility
Localization Localization of GUI and documentation into multiple languages
Other management Traceroute; single IP management; HTTP/HTTPS; SSH; RADIUS; port mirroring; TFTP upgrade;
DHCP client; BOOTP; SNTP; Xmodem upgrade; cable diagnostics; ping; syslog; Telnet client
(SSH secure support)
Power Efficiency
Energy Detect Automatically turns off power off on Gigabit Ethernet RJ-45 port when detecting link down
Active mode is resumed without loss of any packets when the switch detects the link up
Cable length detection Adjusts the signal strength based on the cable length. Reduces the power consumption for cables
shorter than 10m.
General
Jumbo frames Frame sizes up to 10 KB supported on 10/100 and Gigabit interfaces
MAC table Up to 8000 MAC addresses
Discovery
Bonjour The switch advertises itself using the Bonjour protocol.
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 that store the data in a 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.
Power over Ethernet (PoE)
Maximum power of 15.4W to any 10/100 or Gigabit Ethernet base port. The total power available
for PoE per switch is as follows:
