Because Telnet runs over TCP/IP, you must have at least one IP address configured on the switch before you can establish access to it with a virtual terminal protocol.23SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)23SNMP is the standard management protocol for multivendor IP networks. SNMP supports transaction-based queries that allow the protocol to format messages and to transmit information between reporting devices and data-collection programs. SNMP runs on top of the User Datagram Protocol (UDP), offering a connectionless-mode service.23Management Architecture23Web-Based Browser Management24SNMP & RMON Management25Overview25- The RMON probe is an intelligent device or software agent that continually collects statistics about a LAN segment or VLAN. The RMON probe transfers the collected data to a management workstation on request or when a pre-defined threshold is reached.25- The management workstation collects the statistics that the RMON probe gathers. The workstation can reside on the same network as the probe, or it can have an in-band or out-of-band connection to the probe.25SNMP Agent and MIB-2 (RFC 1213)25- Retrieving MIB counters from various layers of software modules according to the SNMP GET/GET NEXT frame messages.26- Setting MIB variables according to the SNMP SET frame message.26- Generating an SNMP TRAP frame message to the Network Management Station if the threshold of a certain MIB counter is reached or if other trap conditions (such as the following) are met:26WARM START26COLD START26LINK UP26LINK DOWN26AUTHENTICATION FAILURE26RISING ALARM26FALLING ALARM26TOPOLOGY ALARM26RMON MIB (RFC 1757) and Bridge MIB (RFC 1493)26RMON Groups Supported26- RMON Statistics Group – maintains utilization and error statistics for the switch port being monitored.26- RMON History Group – gathers and stores periodic statistical samples from the previous Statistics Group.27- RMON Alarm Group – allows a network administrator to define alarm thresholds for any MIB variable. An alarm can be associated with Low Threshold, High Threshold, or both. A trigger can trigger an alarm when the value of a specific MIB variable exceeds a threshold, falls below a threshold, or exceeds or falls below a threshold.27- RMON Event Group – allows a network administrator to define actions based on alarms. SNMP Traps are generated when RMON Alarms are triggered. The action taken in the Network Management Station depends on the specific network management application.27Bridge Groups Supported27- The dot1dBase Group – a mandatory group that contains the objects applicable to all types of bridges.27- The dot1dStp Group – contains objects that denote the bridge’s state with respect to the Spanning Tree Protocol. If a node does not implement the Spanning Tree Protocol, this group will not be implemented. This group is applicable to any transparent only, source route, or SRT bridge that implements the Spanning Tree Protocol.27- The dot1dTp Group – contains objects that describe the entity’s transparent bridging status. This group is applicable to transparent operation only and SRT bridges.27- The dot1dStatic Group – contains objects that describe the entity’s destination-address filtering status. This group is applicable to any type of bridge which performs destination-address filtering.27Web-Based Browser Management28Logging on to the switch28SWITCH IP ADDRESS28LOGIN28Enter the factory default login ID: root.28PASSWORD29Enter the factory default password (no password).29Understanding the Browser Interface30SYSTEM30System Information, System/Password, IP Address, Save Configuration, Firmware Upgrade, Reboot, Logout30PORT30Configuration, Port Status, Rate Control, RMON Statistics, Per Port Vlan Activities30SWITCHING30Bridging, Static MAC Entry, Port Mirroring30TRUNKING30STP30VLAN31VLAN Mode Setting, 802.1Q VLAN Port Setting, 802.1Q Port Setting, Port Based VLAN31QOS31Global Configuration, 802.1p priority, DSCP31SNMP31802.1X31OTHER PROTOCOLS31System32System Information32Port42Switching47Trunking50STP / Ring51VLAN54QoS61SNMP64802.1x69Port-Based Authentication72Other Protocols74Command Line Console Management79Administration Console79Exec Mode (View Mode)80Privileged Exec Mode (Enable Mode)84Configure Mode (Configure Terminal Mode)88System92System Information, System Name/Password, IP Address, Save Configuration, Firmware Upgrade, Reboot, Logout.92Port100Configuration, Port Status, Rate Control, RMON Statistics, Per Port Vlan Activities.100Switching104Bridging, Static MAC Entry, Port Mirroring104Trunking109Port Trunking109STP / Ring110Global Configuration, RSTP Port Setting, Ring Setting110VLAN118QoS124SNMP127802.1x136Other Protocols141Specifications152LED Indicators152Operating152Temperature152Appendix A154Appendix B155サイズ: 14.2MBページ数: 161Language: Englishマニュアルを開く
