Data Sheet

Feature

Description

Port mirroring

Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe.

Up to 8 source ports can be mirrored to one destination port.

VLAN mirroring

Traffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe. Up

to 8 source VLANs can be mirrored to one destination port.

DHCP (Options 12, 66, 67,

82, 129, and 150)

DHCP options facilitate tighter control from a central point (DHCP Server), to obtain IP address, auto

configuration (with configuration file download), DHCP Relay, and host name.

Auto configuration with

Secure Copy (SCP) file

download

Enables secure mass deployment with protection of sensitive data.

Text-editable configs

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.

Auto Smartports

Automatically applies the intelligence delivered through the Smartports roles to the port based on the

devices discovered over Cisco Discovery Protocol or LLDP-MED. This facilitates zero touch

deployments.

Secure Copy (SCP)

Securely transfer files to and from the switch.

Textview CLI

Scriptable CLI. A full CLI as well as a menu CLI is supported.

Cloud Services

Support for Cisco Small Business and Cisco OnPlus.

Localization

Localization of GUI and documentation into multiple languages.

Configurable multiple banners for web as well as CLI.

Time-based port operation

Link up or down based on user-defined schedule (when the port is administratively up).

Other management

Traceroute; single IP management; HTTP/HTTPS; SSH; RADIUS; port mirroring; TFTP upgrade; DHCP

client; BOOTP; Simple Network Time Protocol (SNTP); Xmodem upgrade; cable diagnostics; Ping;

syslog; Telnet client (SSH secure support); Automatic time settings from Management Station.

Green (Power Efficiency)

Energy Detect

Automatically turns 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 is up.

Cable length detection

Adjusts the signal strength based on the cable length. Reduces the power consumption for cable shorter

than 10m. Supported on Gigabit Ethernet models.

EEE compliant (802.3az)

Supports IEEE 802.3az on all Gigabit copper ports.

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 Ethernet interfaces. The default

MTU is 2K.

MAC table

16K (16384) MAC addresses.

Discovery

Bonjour

The switch advertises itself using the Bonjour protocol.

LLDP (802.1ab) with LLDP-

MED extensions

Link Layer Discovery Protocol (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 (CDP). It also learns the connected

device and its characteristics via CDP.

Product Specifications

Power over Ethernet (PoE)

IEEE 802.3af and 802.3at

PoE delivered over any of

the RJ-45 ports within the

listed power budgets

Switches support 802.2af, 802.3at, and Cisco pre-standard (legacy) PoE. Maximum power of 30W to

any 10/100 or Gigabit base port until the PoE budget for the switch is reached. The total power available

for PoE per switch is:
