User’s Manual of GS-5220 PoE Series Managed Switch 3. SWITCH MANAGEMENT This chapter explains the methods that you can use to configure management access to the Managed Switch. It describes the types of management applications and the communication and management protocols that deliver data between your management device (workstation or personal computer) and the system. It also contains information about port connection options.
User’s Manual of GS-5220 PoE Series Managed Switch 3.2 Management Access Overview The Managed Switch gives you the flexibility to access and manage it using any or all of the following methods: An administration console Web browser interface An external SNMP-based network management application The administration console and Web browser interface support are embedded in the Managed Switch software and are available for immediate use. Each of these management methods has their own advantages.
User’s Manual of GS-5220 PoE Series Managed Switch 3.3 Administration Console The administration console is an internal, character-oriented, and command line user interface for performing system administration such as displaying statistics or changing option settings. Using this method, you can view the administration console from a terminal, personal computer, Apple Macintosh, or workstation connected to the Managed Switch's console (serial) port.
User’s Manual of GS-5220 PoE Series Managed Switch You can change these settings, if desired, after you log on. This management method is often preferred because you can remain connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port, regardless of the interface through which the associated action was initiated. A Macintosh or PC attachment can use any terminal-emulation program for connecting to the terminal serial port.
User’s Manual of GS-5220 PoE Series Managed Switch 3.5 SNMP-based Network Management You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMP Network Manager, HP Openview Network Node Management (NNM) or What’s Up Gold. This management method requires the SNMP agent on the switch and the SNMP Network Management Station to use the same community string.

User’s Manual of GS-5220 PoE Series Managed Switch Every physical port on a switch has a PVID. 802.1Q ports are also assigned a PVID, for use within the switch. If no VLAN are defined on the switch, all ports are then assigned to a default VLAN with a PVID equal to 1. Untagged packets are assigned the PVID of the port on which they were received. Forwarding decisions are based upon this PVID, in so far as VLAN are concerned. Tagged packets are forwarded according to the VID contained within the tag.
User’s Manual of GS-5220 PoE Series Managed Switch ■ Port Overlapping Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can connect them by enabled routing on this switch. ■ Untagged VLANs Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security.

User’s Manual of GS-5220 PoE Series Managed Switch Mirroring For debugging network problems or monitoring network traffic, the switch system can be configured to mirror frames from multiple ports to a mirror port. (In this context, mirroring a frame is the same as copying the frame.) Both incoming (source) and outgoing (destination) frames can be mirrored to the mirror port. MLD MLD is an acronym for Multicast Listener Discovery for IPv6.
User’s Manual of GS-5220 PoE Series Managed Switch NFS allows the system administrator to store resources in a central location on the network, providing authorized users continuous access to them, which means NFS supports sharing of files, printers, and other resources as persistent storage over a computer network. NTP NTP is an acronym for Network Time Protocol, a network protocol for synchronizing the clocks of computer systems. NTP uses UDP (datagrams) as transport layer.
User’s Manual of GS-5220 PoE Series Managed Switch PHY is an abbreviation for Physical Interface Transceiver and is the device that implement the Ethernet physical layer (IEEE-802.3). PING Ping is a program that sends a series of packets over a network or the Internet to a specific computer in order to generate a response from that computer. The other computer responds with an acknowledgment that it received the packets.
User’s Manual of GS-5220 PoE Series Managed Switch Q QCE QCE is an acronym for QoS Control Entry. It describes QoS class associated with a particular QCE ID. There are six QCE frame types: Ethernet Type, VLAN, UDP/TCP Port, DSCP, TOS, and Tag Priority. Frames can be classified by one of 4 different QoS classes: "Low", "Normal", "Medium", and "High" for individual application. QCL QCL is an acronym for QoS Control List.
User’s Manual of GS-5220 PoE Series Managed Switch a given hardware address, such as an Ethernet address. RARP is the complement of ARP. RADIUS RADIUS is an acronym for Remote Authentication Dial In User Service. It is a networking protocol that provides centralized access, authorization and accounting management for people or computers to connect and use a network service. RDI RDI is an acronym for Remote Defect Indication.
User’s Manual of GS-5220 PoE Series Managed Switch Protocol (TCP) and provides a mail service modeled on the FTP file transfer service. SMTP transfers mail messages between systems and notifications regarding incoming mail. SNAP The SubNetwork Access Protocol (SNAP) is a mechanism for multiplexing, on networks using IEEE 802.2 LLC, more protocols than can be distinguished by the 8-bit 802.2 Service Access Point (SAP) fields.
User’s Manual of GS-5220 PoE Series Managed Switch SyncE Is an abbreviation for Synchronous Ethernet. This functionality is used to make a network 'clock frequency' synchronized. Not to be confused with real time clock synchronized (IEEE 1588). T TACACS+ TACACS+ is an acronym for Terminal Access Controller Access Control System Plus. It is a networking protocol which provides access control for routers, network access servers and other networked computing devices via one or more centralized servers.
User’s Manual of GS-5220 PoE Series Managed Switch Toss is an acronym for Type of Service. It is implemented as the IPv4 Toss priority control. It is fully decoded to determine the priority from the 6-bit Toss field in the IP header. The most significant 6 bits of the Toss field are fully decoded into 64 possibilities, and the singular code that results is compared against the corresponding bit in the IPv4 ToS priority control bit (0~63). TLV TLV is an acronym for Type Length Value.
User’s Manual of GS-5220 PoE Series Managed Switch A method to restrict communication between switch ports. VLANs can be used for the following applications: VLAN unaware switching: This is the default configuration. All ports are VLAN unaware with Port VLAN ID 1 and members of VLAN 1. This means that MAC addresses are learned in VLAN 1, and the switch does not remove or insert VLAN tags. VLAN aware switching: This is based on the IEEE 802.1Q standard. All ports are VLAN aware.
User’s Manual of GS-5220 PoE Series Managed Switch not work with some older network cards (Wikipedia). WPA-PSK WPA-PSK is an acronym for Wi-Fi Protected Access - Pre Shared Key. WPA was designed to enhance the security of wireless networks. There are two flavors of WPA: enterprise and personal. Enterprise is meant for use with an IEEE 802.1X authentication server, which distributes different keys to each user.
