Cisco CBS220 Smart 48-Port GE PoE 4x1G SFP Switch

Management features
Switch type What switch device has, managed or unmanaged.	Managed
Switch layer A network switch is a computer networking device that links networking segments. A switch has different layers, such as layer 2 (a network bridge, operating at the data link layer, interconnecting a small number of devices) and layer 4 (can act as a firewall, amongst other things).	L2
Quality of Service (QoS) support
Web-based management Using a website/web application to manage something.
Configuring Location Settings (CLI)
System event log
MIB support

Ports & interfaces
Basic switching RJ-45 Ethernet ports quantity The number of basic switching RJ-45 Ethernet ports (sockets).	48
Basic switching RJ-45 Ethernet ports type The type/category of basic switching RJ-45 Ethernet ports (sockets).	Gigabit Ethernet (10/100/1000)
Installed SFP modules quantity An SFP ("small form-factor pluggable transceiver") is a transmitter/receiver which interfaces a network device motherboard (e.g. in a switch, router) to a fibre optic or copper network cable. The "SFP ports quantity" is the number of ports for SFP connections in a device.	4

Network
Networking standards The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g.	IEEE 802.3ab, IEEE 802.3ad, IEEE 802.3af, IEEE 802.3u, IEEE 802.3x, IEEE 802.3at, IEEE 802.3z, IEEE 802.1D, IEEE 802.1w, IEEE 802.1x
10G support The product can use Oracle 10G, which is a database management system introduced in 2003.
Port mirroring
Flow control support
Link aggregation
Broadcast storm control
Auto MDI/MDI-X A Medium Dependent Interface (MDI) describes the interface (both physical and electrical) in a computer network from a physical layer implementation to the physical medium used to carry the transmission. Ethernet over twisted pair also defines a medium dependent interface crossover (MDIX) interface. Auto-MDIX ports on newer network interfaces detect if the connection would require a crossover, and automatically chooses the MDI or MDIX configuration to properly match the other end of the link.
Spanning tree protocol
Head-of-line (HOL) blocking
VLAN support A Virtual Local Area Network (VLAN) consists of a group of computers and switches that can be physically distributed over different networks and buildings, but form one LAN on a logical level.
Number of VLANs	256

Data transmission
Switching capacity The data transfer capacity of the switch per second.	104 Gbit/s
MAC address table The MAC address is the 'Media Access Control Address'. It is a unique address given to a network interface controller (NIC) in a device. A MAC address table shows the addresses in a table format.	8192 entries
Jumbo frames support
Jumbo frames	9216

Security
DHCP features	DHCP client
Access Control List (ACL)
Access Control List (ACL) rules	512
IGMP snooping
IGMP entries	256
Security algorithms Security algorithms are used to provide authentication, cipher key generation, integrity and radio link privacy to users on mobile networks. The security algorithms supported are the ones that can be used with this product.	SSL/TLS
MAC address filtering Security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists.
SSH/SSL support
Loop protection
BPDU filtering/protection

Multicast features
Multicast support
Number of multicast groups filtered	256

Protocols
Management protocols	SNMP
GARP VLAN Registration Protocol (GVRP)

Design
Rack mounting The type of mounting that can position devices in a shelving system (rack).
Product colour The colour e.g. red, blue, green, black, white.	White
Reset button
LED indicators
Number of fans The quantity of fans (apparatus with rotating blades that creates a current of air for cooling or ventilation).	1 fan(s)

Performance
Firmware upgradeable

Power
AC input frequency	50/60 Hz

Power over Ethernet (PoE)
Power over Ethernet (PoE) The device supports Power over Ethernet (PoE), which is one of several standardized or ad-hoc systems which pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points or IP cameras.
Power over Ethernet (PoE) ports quantity	48
Total Power over Ethernet (PoE) budget	382 W

Operational conditions
Operating temperature (T-T) The minimum and maximum temperatures at which the product can be safely operated.	0 - 50 °C
Storage temperature (T-T) The minimum and maximum temperatures at which the product can be safely stored.	-20 - 70 °C
Operating relative humidity (H-H)	10 - 90%
Storage relative humidity (H-H)	10 - 90%

Weight & dimensions
Width The measurement or extent of something from side to side.	440 mm
Depth The distance from the front to the back of something.	257 mm
Height The measurement of the product from head to foot or from base to top.	44 mm
Weight Weight of the product without packaging (net weight). If possible, the net weight is given including standard accessories and supplies. Please note that sometimes the manufacturer leaves out the weight of accessories and/or supplies.	5.29 kg
