Feature |
Description |
||
Ports |
8 Gigabit Ethernet |
8 Gigabit Ethernet |
- |
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 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 |
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 |
