Chapter 3 Managing ITP Networks Using SGM Configuring SNMP Note If you want to change SNMP settings, do so before running Discovery. To change SNMP settings in SGM: Step 1 Start the SGM client, as described in the “Starting SGM” section on page 2-2. Step 2 Select Edit > SNMP Configuration from the SGM Main Menu. (If you have implemented SGM User-Based Access, this option is available to users with authentication level Network Administrator [Level 4] and higher.) SGM displays the SNMP Config

Chapter 3 Managing ITP Networks Using SGM Configuring SNMP Step 4 (Optional) To change the IP address or DNS name of a node, select the node and enter the new address or name in the IP Address Range or Hostname field. � IP addresses use the format x.x.x.x, where each x has one of the following values: – An integer in the range 0 through 255. – A range of integers separated by a dash (-), such as 10-60. – An asterisk (*), which is equivalent to specifying 0-255. � Unlike IP addresses, you can

Chapter 3 Managing ITP Networks Using SGM Configuring SNMP Step 8 (Optional) If you determine that SGM polls a node too often, or not often enough, you can change the poll interval. To change the time, in minutes, between polls for a node, select the node and enter the new interval in the Poll Interval (mins) field. The valid range is 5 to 1440. The default value is 15 minutes. Click Update to apply the new poll interval to the selected node. Step 9 (Optional) To add a new node or range of

Chapter 3 Managing ITP Networks Using SGM Discovering the Network Discovering the Network SGM uses a Discovery process to populate the SGM database, discovering the nodes, signaling points, linksets, and links in your network. You can run Discovery if SGM User-Based Access is disabled, or if it is enabled and you are a Network Administrator or System Administrator. (For more information about user authorization levels in SGM, see the “Configuring SGM User Authentication Levels (Solaris Onl

Chapter 3 Managing ITP Networks Using SGM Discovering the Network To discover the network in SGM: Step 1 Start the SGM client, as described in the “Starting SGM” section on page 2-2. Step 2 Select Edit > Network Discovery from the SGM Main Menu. SGM displays the Discovery Dialog (Figure 3-2). Figure 3-2 Discovery Dialog If you start the SGM client and the SGM database is empty (including the very first time you start the SGM client), SGM automatically opens the Discovery Dialog so you can r

SGM displays details of the SNMP settings for the seed nodes in the right pane of the window. Continue adding seed nodes until you are certain that SGM will be able to discover the entire network. � If you have already created and saved a seed fil

To recover from this situation and generate a new, complete, and reliable SGM database, you must perform one of the following procedures: a. Run Discovery again, with both Entire Network and Delete Existing Data selected. b. Change the

Chapter 3 Managing ITP Networks Using SGM Discovering the Network The Discovered Nodes section displays the following information for each discovered node: � Internal ID—Internal ID of the event. The internal ID is a unique ID for every event, link, linkset, signaling point, and node, assigned by SGM for its own internal use. It can also be useful when the TAC is debugging problems. � Name—Name or IP address of the discovered node. � Primary SNMP Address—IP address of the node, used by SNMP

Chapter 3 Managing ITP Networks Using SGM Configuring Seed Files You can run Discovery multiple times to attempt to discover additional nodes based on the IP address defined in the Stream Control Transmission Protocol (SCTP) linksets. If you are using a separate management VLAN to manage your nodes, but private or unreachable IP addresses for your SCTP connectivity, clear the Entire Network checkbox in the Discovery Dialog. Otherwise, Discovery attempts to reach those nodes continuously.
