Explanation in Detail
In general, Cisco switches’ models are started with WS-. WS-C means the switch products and the products with WS-X begining refer to the engines or modules of switches. In addition, there is WS-G which means the Gigabit fiber optic transceiver modules of switches. Now, I explain the detailed meaning of each letter in the model through a few of examples.
eg. WS-C3560G-24TS-S

  • W — stands for IPSEC 40bit encryption;
  • S — means switchboard;
  • C — means the fixed-configuration switch;
  • 3650 — refers to the seires;
  • G — means all the interfaces are supported Gigabit or more. If there is no letter “G” here, it shows that the mainly port of this switch is 10/100M or 100M;
  • 24 — here means there are 24 ports of this switch;
  • T — stands for port of BaseT port; sometimes, there is letter “P” here which means BaseT port which supports PoE at the same time;
  • S — the S behind T means the extended interface is SFP type interface and uplink;

Note: There are also “D” or “C” or “W”repalcing “T” or “S” here, which respectively means 10Gigabit Ethernet XENPAK port and uplink, T/SPF and uplink, Integrated wireless LAN controller(50 support for up to 50 access points). Some combination meaning as following:
TT — common port and uplink port are both BaseT;
LC — common port is BaseT and partially support PoE(4 ports) uplink port are BaseT/SFP;
PC — common port is BaseT and all support PoE(24 ports) uplink port are BaseT/SFP;
TC –common port is BaseT and uplink port are all BaseT/SFP;
TS — common port is BaseT and uplink port are all SFP;
PS — common port is BaseT and all support the PoE, uplink port are all SFP;
FS — common port is 100BaseFX and uplink port are all SFP;
when there is only T, it means there is no uplink port in the switch.

 

Features and Benefits

Benefit

Ease of 
Use and Deployment

•  Autoconfiguration of new stack units eliminates reconfiguration.

•  Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment.

•  Automatic Cisco IOS Software version checking and updating help ensure that all stack members have the same software version.

•  Automatic QoS (AutoQoS) simplifies QoS configuration in voice over IP (VoIP) networks by issuing interface and global switch commands to detect Cisco IP phones, classify traffic, and help enable egress queue configuration.

•  Master configuration management helps ensure that all switches are automatically upgraded when the master switch receives a new software version.

•  Autosensing on each non-SFP port detects the speed of the attached device and automatically configures the port for 10-, 100-, or 1000-Mbps operation, easing switch deployment in mixed 10, 100, and 1000BASE-T environments.

•  Autonegotiating on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.

•  Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.

•  Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel ® groups or Gigabit EtherChannel groups to link to another switch, router, or server.

•  Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP.

•  DHCP Relay allows a DHCP relay agent to broadcast DHCP requests to the network DHCP server.

•  IEEE 802.3z-compliant 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, and CWDM physical-interface support through a field-replaceable SFP module provides unprecedented flexibility in switch deployment.

•  There is a default configuration to help ensure that the switch can be quickly connected to the network and can pass traffic with minimal user intervention. This default configuration exists even if there is no configuration stored in Flash memory.

•  Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.

•  Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source to destination.

•  All 9 RMON groups are supported through a SPAN port, which permits traffic monitoring of a single port, a group of ports, or the entire stack from a single network analyzer or RMON probe.

•  Domain Name System (DNS) provides IP-address resolution with user-defined 
device names.

?  Customers can provide power to a switch by using either the internal power supply or a redundant power system (Cisco RPS 2300 or the Cisco RPS 675). The connectors are located at the back of the switch.

?  Internal power supply connector

?  The internal power supply is an autoranging unit.

?  The internal power supply supports input voltages between 100 and 240VAC.

?  Use the supplied AC power cord to connect the AC power connector to an AC power outlet.

?  Cisco RPS Connector

?  The connector offers connection for an optional Cisco RPS 2300 or RPS 675 that uses AC input and supplies DC output to the switch.

•  The connector automatically senses when the internal power supply of a connected device fails and provides power to the failed device, preventing loss of network traffic.
