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. User
privilege levels 1, 7, and 15 is supported for the CLI.
Cloud services Support for Cisco Small Business FindIT Network and Cisco OnPlus
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)
Time-based port operation Link up or down based on user-defined schedule (when the port is administratively up)
Login banner Configurable login banners for web as well as CLI
Power Efficiency
EEE Compliant (802.3az) Supports 802.3az on all copper ports (SG300 models)
Energy Detect Automatically turns off power off on Gigabit Ethernet and 10/100 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 for Gigabit Ethernet models. Reduces the
power consumption for cables shorter than 10m.
Disable port LEDs LEDs can be manually turned off to save on Energy
General
Jumbo frames Frame sizes up to 9K (9216) bytes supported on 10/100 and Gigabit interfaces
MAC table Up to 16K (16384) 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 (CDP) The switch advertises itself using the Cisco Discovery Protocol. It also learns the connected device
and its characteristics via CDP.
Power over Ethernet (PoE)
Switches support 802.3at PoE+, 802.3af, and Cisco pre-standard (legacy) 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:

delivered over any of the RJ-45
ports within the listed power
budgets
