User manual for the Cisco 300 Series SG300-28MP 28-Port PoE Gigabit SG300-28MP-K9-NA
The user manual for the Cisco 300 Series SG300-28MP 28-Port PoE Gigabit SG300-28MP-K9-NA provides
necessary instructions for the proper use of the product Computers & Solutions - Networking - Network Switches, Bridges & Hubs.
The SG300-28MP 28-Port PoE Gigabit Ethernet Switch from Cisco allows small businesses to connect its employees with each other and with all of the servers, printers, IP phones, and other devices they use. This mountable switch offers 128MB of RAM, 16MB flash memory, and 26 Gigabit Ethernet plus 2 Gigabit Ethernet Combo ports. 24 of these ports are PoE ports, which provide power over a single Ethernet cable to devices such as IP telephony, wireless, and IP surveillance. It also prioritizes services such as voice and video to help ensure consistent network performance for all services. For security to keep your network safe, this switch features denial-of-service prevention, guest virtual LANs, access control lists, and more.
Cisco has included a device manager software that provides a web-based interface to guide users without IT experience in setup, security, and quality of service traffic prioritization. Cisco has other features that automatically detects the devices connected to the network and displays the serial numbers and IP address. It then instructs the devices to use the appropriate bandwidth parameters and the specific level of security. Included with the switch are a power cord, mounting hardware, serial cable, and a CD-ROM disc.

Discovery
Bonjour: The switch advertises itself using the Bonjour protocol. 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 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. It also learns the connected device and its characteristics via CDP.
Layer 2 Switching
Spanning Tree Protocol (STP) Standard 802.1d Spanning Tree support Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default 8 instances are supported Multiple Spanning Tree instances using 802.1s (MSTP)
Port grouping Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
Up to 8 groups
Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation
VLAN Support for up to 4096 VLANs simultaneously Port-based and 802.1Q tag-based VLANs MAC-based VLAN Management VLAN Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks Guest VLAN Unauthenticated VLAN CPE VLAN
Voice VLAN Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS Auto voice capabilities deliver network-wide zero touch deployment of voice endpoints and call control devices
Multicast TV VLAN Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs (Also known as MVR)
Q-in-Q VLAN VLANs transparently cross a service provider network while isolating traffic among customers
Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP Protocols for automatically propagating and configuring VLANs in a bridged domain
Unidirectional Link Detection (UDLD) UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks
Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2 Relay of DHCP traffic to DHCP server in different VLAN. Works with DHCP Option 82
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 1K multicast groups (source-specific multicasting is also supported)
IGMP Querier IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
Head-of-line (HOL) blocking HOL blocking prevention
Jumbo Frames Up to 9 K bytes

DHCP Server Switch functions as an IPv4 DHCP Server serving IP addresses for multiple DHCP pools/scopes Support for DHCP options
Security
Secure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
Web Based Authentication Web based authentication provides network admission control through web browser to any host devices and operating systems.
STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port.
STP Root Guard This prevents edge devices not in the network administrator's control from becoming Spanning Tree Protocol root nodes.
DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP Server.
IP Source Guard (IPSG) When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address Spoofing.
Dynamic ARP Inspection (DAI) The switch discards ARP packets from a port if there is no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. This prevents man-in-the-middle attacks.
IP/Mac/Port Binding (IPMB) The features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) above work together to prevent DOS attacks in the network, thereby increasing network availability.
Secure Core Technology (SCT) Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received.
Secure Sensitive Data (SSD) A mechanism to manage sensitive data (such as passwords, keys, etc) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user configured access level and the access method of the user.
Layer 2 isolation Private VLAN Edge (PVE) with community VLAN PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks.
Port security The ability to lock Source MAC addresses to ports, and limits the number of learned MAC addresses.
RADIUS/TACACS+ Supports RADIUS and TACACS authentication. Switch functions as a client.
Storm control Broadcast, multicast, and unknown unicast
RADIUS accounting The RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the session.
