Introduction Industrial Ethernet OSM/ESM Network Management C79000-G8976-C137-08 1 1-1
Introduction 1.1 Network Management with SNMP The Industrial Ethernet OSMs (Optical Switch Modules) and Industrial Ethernet ESMs (Electrical Switch Modules) have SNMP and Web Based Management. This chapter briefly explains the basics of network management with SNMP and Web-Based Management. In the past, homogeneous office networks installed with components from one manufacturer could also be maintained and administered with the proprietary management systems provided by the manufacturer.
Introduction 1.1.2 Communication Protocol SNMP uses the connectionless protocol UDP (User Datagram Protocol). Getting Information To read the required status information, the manager sends a Get request to the agent of the device. The addressed component answers the request with a Response message. Making Settings To change the current configuration of a managed device, the manager sends a Set request.
Introduction Network management station with management software (e.g. PC with CP 1613 or MOBIC) 100 Mbps RM 100 Mbps 100 Mbps Access by the management station to the switch module via SNMP. 10 Mbps ... Figure 1-2 1.1.3 Communication Between a Management Station and Switch Management for Industrial Networks MIB The MIB is a data structure made up of different variables (management objects) that can be polled or set by the management system.
Introduction 1.2 Network Management for Industrial Networks The trend towards larger and larger structures in industrial networks has been apparent for some time. Vertical integration, in other words the growing together of industrial networks and office networks, allows transparent access to all data but also requires integrated diagnostic functions. To meet the new requirements of this situation, the SIMATIC NET signaling concept using a signaling contact has been extended to include network management.
Introduction 1.2.3 Web-Based Management (WBM) To allow users to introduce network management cost-effectively, Web-Based Management is available for network management and diagnostics with the SIMATIC NET switch modules. With the aid of Web-Based Management, it is possible to address individual network nodes or DTEs using an Internet browser such as the Netscape Communicator or Internet Explorer.
Introduction Applet of the addressed component (in the example OSM) Network management station with Web browser Access from the management station to the monitored network node 100 Mbps ...
Introduction 1.3 Command Interpreter (CLI) In addition to the Web-Based Management, you can also change or query all the important parameters of an OSM/ESM using a terminal with a V24 interface (for example a PC with the Windows Hyperterminal program). The terminal is connected to the serial port of the OSM/ESM. The functions of the OSM/ESM are manipulated using a simple command interpreter (CLI, Command-Line Interface). TELNET also provides the same functionality. 1.
Important OSM/ESM Functions Industrial Ethernet OSM/ESM Network Management C79000-G8976-C137-08 2 2-1
Important OSM/ESM Functions 2.1 Autonegotiation In the autonegotiation mode, an electrical OSM/ESM port sets itself automatically to the transmission rate (10/100 Mbps) of the connected partner device. If the partner device also supports autonegotiation, the devices further negotiate whether they will exchange data in the half-duplex or full-duplex mode and full-duplex flow control.
Important OSM/ESM Functions 2.2 Autocrossover Electrical OSM/ESM ports with the autocrossover function are capable of crossing over the send and receive signals internally in the port. This means that straight-through or crossover TP cables can be used without causing problems. To use the autocrossover function: S At least one of the two ports must support the autocrossover function. S The autonegotiation mode must be set on the port providing the autocrossover function.
Important OSM/ESM Functions 2.4 Factory Defaults and Protected Settings Defaults The OSM/ESM had default settings made in the factory (see 4.7.3Factory Defaults). The user can query and modify these defaults with WBM, the CLI or SNMP. The screenshots of the WBM dialogs in Chapter 4 show the default settings. You will find further default settings in the private MIB file (see Section 4.7.3).
Important OSM/ESM Functions 2.5 Filtering Database (FDB Table) The FDB (Filtering Database ) table is used by the OSM/ESM to decide which port or ports a received packet is transferred to. The FDB table of the OSM/ESM can hold up to 7000 addresses. 2.5.1 Entries in the FDB Table The FDB table contains two types of entries (addresses): S Static MAC addresses: These can be entered and deleted by the user with WBM or SNMP.
Important OSM/ESM Functions 2.5.2 Displaying and Deleting FDB Entries, Aging The entries in the FDB table can be displayed by the WBM, see Section 4.10.1. Static addresses can also be entered or deleted in WBM. If aging is activated (default), a learned entry (address) is automatically deleted in the FDB table when no packet with this source address is received within the aging time. Aging prevents addresses that are no longer up to date from remaining in the FDB table permanently.
Important OSM/ESM Functions Note The OSM/ESM passes on all spanning tree frames regardless of the function described above. The OSM/ESM itself does not send any spanning tree frames. The times involved in configuration changes depend on the spanning tree configuration and the network topology. The actual time required to change the configuration must be determined based on tests.
Important OSM/ESM Functions 2.6 Locked Ports Locking Locking is used to make sure that only packets from authorized stations are passed on by the OSM/ESM. Lock Enabled If the lock enabled function is activated for an OSM/ESM port, the OSM/ESM only passes on packets received at this port if the source address exists in the FDB table. All other packets are discarded.
Important OSM/ESM Functions 2.7 Mirroring Mirroring for Diagnostics Mirroring allows you to mirror (copy) the bi-directional data traffic to an OSM/ESM port (mirrored port) to another OSM/ESM port (monitor port) and to record it with a protocol analyzer for diagnostic purposes. Settings You can set the mirrored and monitor port and activate the mirror function both with the command-line interface or using WBM. Ports 1 to 6 of the OSM/ESM can be used as the monitor port.
Important OSM/ESM Functions 2.8 Traps Trap Messages If certain events occur, the OSM/ESM can generate (SNMP) trap messages and send them to up to 10 different nodes, for example management stations. By configuring the management station, the traps can be displayed on the user interface. An interpreted display is possible only when the corresponding MIB files can be evaluated by the management station.
Important OSM/ESM Functions 2.9 E-Mail Function The OSM/ESM has an E-mail function with which an E-mail can be sent automatically (for example to the network administrator) if an alarm occurs. If the E-mail function is activated, the OSM/ESM sends an E-mail in the same situations that lead to a trap being issued (see Section 2.8). The E-mail includes the identification of the sending OSM/ESM and a description of the cause of the alarm in plain language.
Important OSM/ESM Functions 2.10 Event Log Table Events are entered chronologically in the event log table (log book) of the OSM/ESM. The events include: S all events reported, including those via E-mail and trap, S additional error messages if an E-mail server (SMTP) is not accessible or rejects the E-mail of an OSM/ESM. The event log table can be read out using the command line interface (see section 3.5) over the Web Based Management (see Section 4.7.5) or using direct SNMP access.
Important OSM/ESM Functions 2.11 Time of Day and Time- of - day Synchronization The OSM/ESM has two times: 1. System Up Time: The time since the OSM/ESM was last restarted. The system up time is added to every E-mail and every entry in the event log table. After 497 days, the system up time starts again at 0. This oberflow results from the range of values of the standard MIB object (OID 1.3.6.1.2.1.1.3). 2.
Important OSM/ESM Functions 2.12 Flow Control Flow control is a mechanism that reduces the risk of data loss in the network resulting from overload. The OSM/ESM supports two flow control mechanisms: S Half Duplex Flow Control (Back Pressure) for ports operating in the half duplex mode. With this type of flow control, the OSM/ESM reduces the packet rate received at a port if there is overload in the network by generating additional collisions. S Full Duplex Flow Control complying with the IEEE 802.
Important OSM/ESM Functions 2.13 BOOTP/DHCP If there is a BOOTP or DHCP server in your network, the OSM/ESM can automatically obtain the following from the server: S the IP address, S the subnet mask, S the IP address of the default gateway, S the IP address of the TFTP server, S the configuration file (Section 2.17) / or the firmware file name If the BOOTP/DHCP function is activated on the OSM/ESM (default), BOOTP and DHCP are always started after starting up the device.
Important OSM/ESM Functions 2.14 IP Configuration Using SIMATIC NET NCM PC, SIMATIC STEP 7 or the Primary Setup Tool Just as several other SIMATIC NET products, the OSM/ESM also supports IP configuration (IP address, subnet mask, gateway) using SIMATIC NET NCM PC, SIMATIC STEP 7 or the Primary Setup Tool. For more detailed information, refer to the documentation of the relevant product. Note 2-16 S SIMATIC NET NCM PC and SIMATIC STEP 7 support IP configuration as of version 5.2.
Important OSM/ESM Functions 2.15 TELNET With TELNET, you can operate the CLI of the OSM/ESM via the LAN/Internet. You can start a TELNET link to the OSM/ESM, for example, by clicking on the console icon in the login window of the OSM/ESM WBM, see Chapter 4. Note A maximum of 3 CLI links (serial + LAN) are possible at the same time.
Important OSM/ESM Functions 2.16 Extended Redundant Configuration Redundant Coupling With OSMs/ESMs (except for the OSM TP22 and ESM TP40), you can implement redundant links, see /1/. A redundant coupling is created using two OSMs/ESMs, one of which is set to the standby slave with the DIP switch (”Stby on”) while the other operates as the standby master. The standby-sync ports of both OSMs/ESMs are interconnected using an ITP XP standard cable 9/9, see Figure 2-1.
Important OSM/ESM Functions Extended Redundant Configuration with Network Management The extended redundant configuration of the OSM/ESM (with the exception of the OSM TP22 and ESM TP40) allows up to 8 rings or networks to be coupled redundantly with two OSMs/ESMs (see also /1/) With network management (for example in WBM), each port of the standby master and standby slave can be configured as a standby port, see Figure 2-2. The other ports can be used as “normal” OSM/ESM ports.
Important OSM/ESM Functions In problem-free operation, only the standby ports of the standby master are active and handle data exchange. If the standby master or the link of one of the standby ports of the master fails, all standby ports of the master are disabled and the standby ports of the slave activated so that a functioning configuration is re-established. Note Please remember that the same ports on the standby master and standby slave must be configured as the standby ports.
Important OSM/ESM Functions 2.17 Observer Function The observer function provides further opportunities for error diagnostics and error protection for redundant rings. It allows malfunctions of the redundancy manager or bad configuration of a redundant ring to be monitored. The Observer is also capable of opening the connected ring when the errors are detected (portection mode). The function is optional and as default deactivated.
Important OSM/ESM Functions Table 2-2 Status 2-22 Meaning Possible Cause disabled (1) Observer function is disabled. starting (1) The Observer is waiting for test frames from the RM. monitoring (1) The Observer monitors the RM function. This is the normal state. rm error : hardware fault(2) rm cfg/hardware error rm error : test frames missing rm error : rm status mismatch (2) Remedy The Observer was started but no RM was found.
Important OSM/ESM Functions 2.18 Automatic Download of the Configuration If the file name and folder of a configuration file is specified on the BOOTP server or DHCP server, the BOOTP/DHCP client of the OSM/ESM can trigger an automatic download of the configuration data over TFTP. Requirements The BOOTP and TFTP servers must be configured and started on the same station under one IP address. BOOTP must be activated on the OSM.

Web-Based Management (WBM) Industrial Ethernet OSM/ESM Network Management C79000-G8976-C137-08 4 4-1
Web-Based Management (WBM) 4.1 General Introduction The OSM/ESM includes integrated Web-Based Management; in other words, it can be operated using an Internet browser. The modules are operated using a Java applet stored on the OSM/ESM that is loaded by the browser. To access the OSM/ESM, the IP address must be entered in the address field of the browser. If there is a DNS server in your network that can interpret the address of the OSM/ESM, you can also access the module using the logical name. 4.1.
Web-Based Management (WBM) 4.2 Requirements To access an OSM/ESM using WBM, the following requirements must be met: Internet Browser You require a PC with an Internet browser. As the Internet browser, we recommend a Netscape Communicator, Version 4.7 or a Microsoft Internet Explorer, Version 5.0 or higher. Before your Internet browser will work with the OSM/ESM, you must make the correct settings in the browser. For more information, refer to Appendix A of this manual.
Web-Based Management (WBM) 4.3 Connecting Connect the Internet browser station and the OSM/ESM with the following configuration.
Web-Based Management (WBM) 4.4 Access Using Web-Based Management You can access the OSM/ESM using WBM as follows: 1. Open the Internet browser. 2. Enter the IP address or the URL of the OSM/ESM in the address box of the Internet Browser as follows: http:// e.g. http://142.11.7.8 and confirm with [Return]. 3. When the “Login” window appears (Figure 4-2), select admin or user in the Login ID box (to select the access level).
Web-Based Management (WBM) Note If no new passwords have been assigned, the valid password is the default admin (to use WBM as an administrator, for example with write/read permissions) and user (to use WBM as a user with read permissions only). The admin and user passwords can only be modified via the CLI, see 3.5. If you lose the password, you can reset the OSM/ESM to the original defaults with the button on the front panel, see Section 2.4. The admin or user passwords are then valid again.
Web-Based Management (WBM) 4.5 User Interface of Web-Based Management The dialogs of the OSM/ESM WBM are made up of a device status field, a menu tree, and a data window.
Web-Based Management (WBM) Device Status Field The displays in the device status field correspond to the LEDs of the OSM/ESM, see /1/. The swapping over of the meaning of the port LEDs and the power LEDs (with the display button) is not implemented. Instead of this, the transmission rate, duplicity and the fault mask are represented by a separate row of LED symbols. The signaling is identical to the LED signaling of the OSM/ESM, see /1/.
Web-Based Management (WBM) 4.
Web-Based Management (WBM) 4.7 System Clicking the System menu opens the window shown in Figure 4-5. Figure 4-5 System Information Window System Up Time This shows the operating time of the OSM/ESM since the last restart. System Description The System Description box displays the OSM/ESM type.

Set New Values To save the entries made in this window, click the Set New Values button. If you click the Get Current Values button, you obtain the values currently stored on the OSM/ESM. 4.7.
Web-Based Management (WBM) Hardware Hardware version of the OSM/ESM. Order Number Order number of the OSM/ESM. Boot software Version of the boot software of the OSM/ESM. The boot software of the OSM/ESM is used to download new firmware (operative software) to the OSM/ESM and is stored permanently on the OSM/ESM. Operative software Version of the firmware currently loaded on the OSM/ESM. MAC Address MAC address of the OSM/ESM in hexadecimal format.
Web-Based Management (WBM) 4.7.2 System Restart With the System Restart window (Figure 4-7), you can restart the OSM/ESM. Figure 4-7 System Restart Window To restart the OSM/ESM, click the Restart System button. This opens a dialog box in which you are prompted to confirm the “Restart” command. When you restart, the OSM/ESM is reinitialized, the internal firmware is reloaded and a self test is performed on the OSM/ESM hardware.
Web-Based Management (WBM) 4.7.3 System Factory Defaults (restoring the defaults) Figure 4-8 shows the Factory Defaults window. Figure 4-8 System Factory Defaults Window In this window, you can restore the factory default settings for the OSM/ESM. Restore Factory Defaults The settings made in the factory are restored. Even the protected settings (see Section 2.4) are reset. There is no restart so that new data can be entered with the WBM.
Web-Based Management (WBM) 4.7.4 System Save & Load In the Save & Load window, you make the entries required to download the firmware for the OSM/ESM from a TFTP server. The settings for downloading and saving the OSM/ESM configuration and saving the event log table as a file over TFTP can also be made here. Figure 4-9 System Save & Load Window TFTP Server IP Address IP address of the TFTP server from which the new OSM/ESM firmware or a configuration file will be downloaded.
Web-Based Management (WBM) Log Table File Name of the log table file (maximum 32 characters) that is saved on the TFTP server with the Save button. If you do not enter a name for the configuration file and log table file, a file name based on the IP address is used. Firmware File Name of the file on the TFTP server containing the new OSM/ESM firmware (maximum 32 characters), if necessary with additional path information (depending on the configuration of the TFTP server).
Web-Based Management (WBM) 4.7.5 Event Log Table The event log table (Figure 4-10) contains all the events that (if enabled) cause traps or E-mails. Other fault/error events such as communication errors are also logged with the SMTP server. The content of the event log table is therefore retained even when the OSM/ESM is turned off. Figure 4-10 Event Log Table Window When the window is opened the first time, the latest 30 entries in the event log table are displayed.
Web-Based Management (WBM) 4.8 OSM/ESM Status The OSM/ESM Status window (Figure 4-11) shows the mode in which the OSM/ESM is operating and whether errors have been detected by the OSM/ESM. Figure 4-11 OSM/ESM Status Window Standby Mode Enabled: Shows that the OSM/ESM was switched to the standby mode with the DIP switch, see /1/. Disabled: The standby mode is not active (DIP switch on the OSM/ESM set to “Stby off”).
Web-Based Management (WBM) Standby Status Passive: The OSM/ESM is passive; in other words, it does not pass on any packets via the standby ports. Active: The OSM/ESM is active; in other words, it passes on packets via the standby ports. RM Mode Disabled: The OSM/ESM is not operating as the redundancy manager (RM). Enabled: The OSM/ESM is operating as the redundancy manager (DIP switch set to “RM on”).
Web-Based Management (WBM) Fault Status Redundant power line down: Link down on monitored port: Standby configuration error: More than one RM in ring: STBY DIP switch changed. Please restart!: The standby DIP switch setting was changed. As a result, the current operating state is inconsistent with the device configuration.

Web-Based Management (WBM) 4.9.6 Agent SNMP Counters The Agent SNMP Counters window (Figure 4-21) displays counter values defined in the SNMP standard RFC 1213 (MIB-II). The meaning of these counter values is described in RFC 1213. Interpreting the counter values requires detailed knowledge of RFC 1213. The counters can be used, for example, to provide diagnostic information about problems occurring on the link to the SNMP management station.
Web-Based Management (WBM) 4.10 Switch Features Figure 4-22 shows the Switch window. Figure 4-22 Switch Features Window Mirroring Mirroring means that the data exchange at a port (mirrored port) of this OSM/ESM can be “reflected” to another port (monitor port). If a protocol analyzer is connected to the monitor port, it can be used to record the data exchange at the mirrored port without interrupting the connection at the mirrored port.
Web-Based Management (WBM) Aging OSMs/ESMs automatically learn the source addresses of the nodes connected to them. This information is used on the OSM/ESM to pass packets to the intended recipients. This reduces the network load for the other nodes. If the OSM/ESM does not receive a packet with a source address that matches a learned address within the aging time, it deletes the address from the database.
Web-Based Management (WBM) 4.10.1 Current FDB Table Clicking the Current FDB Table menu opens the window with the FDB table of the OSM/ESM shown in Figure 4-23. The FDB table shows which node addresses (MAC addresses) the OSM/ESM has learned and the port on the OSM/ESM via which the node can be reached. The MAC addresses entered as static information by the user are also displayed (see Section 2.4).
Web-Based Management (WBM) Status Shows the status of each FDB entry. ”learned” means that the specified address was learned as a result of receiving a packet from this node. ”static” means that the address was entered as a static address by the user. Static addresses are stored permanently; in other words, they are not cleared after the aging time has elapsed or when the OSM/ESM is restarted.
Web-Based Management (WBM) 4.10.2 Static FDB Table Clicking the Static FDB Table menu opens the window shown in Figure 4-24. This window displays only the static addresses; in other words, the addresses entered by the user.

SNMP and RMON Industrial Ethernet OSM/ESM Network Management C79000-G8976-C137-08 5 5-1
SNMP and RMON 5.1 SNMP With SNMP (Simple Network Management Protocol), a network management station can configure and monitor SNMP-compliant nodes such as the OSM/ESM (from firmware Version 2.0 and higher). To make this possible, a management agent is installed in the DTE with which the management station exchanges data using SNMP Get and Set requests. The OSMs/ESMs support SNMP V1.
SNMP and RMON 5.2 RMON A RMON-compliant device (RMON = Remote MONitoring) allows you to collect special diagnostic data on the device, to prepare this data and to read it out via SNMP at a network management station that supports RMON. This diagnostic data such as port-related load allows you to detect network problems early and to eliminate them. These are stored on the OSM/ESM in the RMON MIB. RMON functionality is defined in RFC 1757 and is divided into groups.

Glossary Autocrossover Capability of automatically crossing over the send and receive signals at twisted -pair ports (automatic switchover between MDI and MDI-X pinning at a port). When, for example, connecting network components, you no longer need crossover cables. The autocrossover function is available only when autonegotiation is activated.
Glossary Boot software The boot software is software integrated on the OSM/ESM that is required to download the OSM/ESM firmware. The boot software cannot be reloaded. Boot version Version of the boot software. Broadcast address Packets with a broadcast address can be read by all nodes in the LAN (destination address FF:FF:FF:FF:FF:FF). CLI Command line interface (see Command interpreter). Collision A collision occurs when two DTEs attempt to send at the same time.
Glossary ESM SIMATIC NET Industrial Ethernet Electrical Switch Module (has only electrical ports). Event log table A table in which certain events detected by the OSM/ESM are stored in non-volatile memory for diagnostic purposes. The log table of the RMON MIB is stored under events and is therefore a dynamic part of the MIB. Fault mask The fault mask is used with the OSM/ESM to mask out certain fault events.
Glossary Half duplex flow control see Back pressure HTML HTML is the abbreviation for Hypertext Markup Language. Using this language it is possible to publish documents in a uniform language on the Web. The main feature of this language is the ability to specify connections to other HTML documents known as URLs. IP address An IP address consists of a numeric code made up of four numbers from 0 to 255 (for example 192.168.0.55). This is the numeric address of a specific computer in the network/Internet.
Glossary Mirroring Mirroring allows you to mirror (copy) the bi-directional data traffic to an OSM/ESM port (mirrored port) to another OSM/ESM port (monitor port) and to record it with a commercially available protocol analyzer for diagnostic purposes. Multicast address A packet with a Multicast address can be received by several nodes prepared to accept this address. Operative software see firmware OSM SIMATIC NET Industrial Ethernet Optical Switch Module (includes optical and electrical ports).
Glossary Power line 1/2 Power supply line 1/2 of the OSM/ESM. Redundancy manager (RM) The OSM/ESM operating as the redundancy manager monitors the line of OSMs/ESMs attached to it. If there is a break on the line, it switches through and therefore recreates a functioning bus configuration. Restart The OSM/ESM can be restarted by the management system (Web Based, CLI, SNMP). RM mode This indicates whether or not an OSM/ESM is operating in the redundancy manager mode (RM on).
Glossary Signaling contact Binary contact used with SIMATIC NET network components to signal fault events. SMTP server (Simple Mail Transfer Protocol Server) computer that receives sent mails and passes them on to the recipient. SNMP Simple Network Management Protocol, nonproprietary LAN management standard. Standby cable Connecting cable (ITP XP standard cable 9/9) for linking the standby master and standby slave in a redundant coupling.
Glossary Static address Static address stored in the OSM/ESM FDB table (non-volatile). Such addresses can be configured by the user with Web management or using SNMP. Subnet mask The subnet mask decides which part of the IP address is used as the subnet address. In a Class B network (subnet mask 255.255.0.0), the first two fields of an IP address (for example 150.215 of the IP address 150.215.017.009) represent the subnet. System contact An SNMP MIB object.
Glossary Trap If certain events occur, the OSM/ESM can generate (SNMP) trap messages and send them to different nodes, for example management stations. These traps contain error messages in plain language that can be displayed by a management station. Unicast address A packet with a Unicast (destination) address is intended for only one node with the corresponding MAC address. Undersize packets Packets with a length of less than 64 bytes.
