Feature

Description

Ports

50 Gigabit Ethernet

48 Gigabit Ethernet

2 Gigabit Ethernet combo

Spanning Tree Protocol (STP)

Standard 802.1d STP support

Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default

Port grouping

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

• Up to 4 groups

• Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation

VLAN

Support for up to 256 VLANs simultaneously (out of 4096 VLAN IDs). 16 VLANs supported in SG200-08
and SG200-08P

Port-based and 802.1Q tag-based VLANs

Voice VLAN

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS

Internet Group Management Protocol (IGMP) versions 1 and 2 snooping

IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups

Head-of-line (HOL) blocking

HOL blocking prevention

IEEE 802.1X
(Authenticator role)

802.1X: RADIUS authentication, MD5 hash

Port security

Locks MAC addresses to ports, and limits the number of learned MAC addresses

Storm control

Broadcast, multicast, and unknown unicast

DoS prevention

DoS attack prevention

Priority levels

4 hardware queues

Scheduling

Strict priority and weighted round-robin (WRR)

Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)

Class of service

Port based, 802.1p VLAN priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ)

Rate limiting

Ingress policer, per VLAN and per port

IPv6

IPv6 host mode

IPv6 over Ethernet

Dual IPv6/IPv4 stack

IPv6 neighbor and router discovery (ND)

IPv6 stateless address auto-configuration

Path maximum transmission unit (MTU) discovery

Duplicate address detection (DAD)

Internet Control Message Protocol (ICMP) version 6

IPv6 over IPv4 network with Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) support

IPv6 QoS

Prioritize IPv6 packets in hardware

Multicast Listener Discovery (MLD) snooping

Deliver IPv6 multicast packets only to the required receivers

IPv6 applications

Web, ping, Simple Network Time Protocol (SNTP), Trivial File Transfer Protocol (TFTP), RADIUS, syslog, DNS client

Web user interface

Built-in switch configuration utility for easy browser-based device configuration (HTTP). Supports configuration, system dashboard, system maintenance, and monitoring

Simple Network Management Protocol (SNMP)

SNMP versions 1, 2c, and 3 with support for traps, and SNMP version 3 user-based security model (USM)

Remote Monitoring (RMON)

Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) 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.

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.

Dynamic Host Configuration Protocol (DHCP) (options 66 and 67)

(DHCP) options facilitate tighter control from a central point (DHCP server) to obtain IP address and perform 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

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.

Cloud services

Support for FindIT Network Discovery Utility and Cisco OnPlus™ technology

Localization

Localization of GUI and documentation into multiple languages

Other management

HTTP, RADIUS, port mirroring, TFTP upgrade, DHCP client, BOOTP, SNTP, ping, syslog

EEE compliant (802.3az)

Supports 802.3az on all copper Gigabit Ethernet ports (SG200-xx models)

Not supported on SG200-08 and SG200-08P models

Energy Detect mode

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 that 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.

Jumbo frames

Frame sizes up to 10 KB supported on 10/100 and Gigabit Ethernet interfaces

(9 KB for SG200-08 and SG200-08P)

MAC table

Up to 8000 MAC addresses

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. It also learns the connected device and its characteristics via this protocol.

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 capability facilitates zero-touch deployments.

Bonjour

The switch advertises itself using the Bonjour protocol

Buttons

Reset button

Cabling type

Unshielded twisted pair (UTP) Category 5 or better for 10BASE-T/100BASE-TX; UTP Category 5 Ethernet or better for 1000BASE-T

LEDs
