218 CHAPTER 6: USING ROUTING PROTOCOL COMMANDS This command cannot be applied to the OSPF processes that are started after the command is executed. By default, the switch does not send TRAP packets in case of OSPF anomalies. For detailed configuration of SNMP TRAP, see "Using System Management Commands" on page 397. Example Enable the TRAP function for OSPF process 100. system-view System View: return to User View with Ctrl+Z. [SW5500]snmp-agent trap enable ospf 100 spf-schedule-interval Syntax spf-schedule-interval interval undo spf-schedule-interval View OSPF View Parameter interval Enter the SPF route calculation interval for OSPF, in seconds, in the range 1 to 10. The default value is 5 seconds. Description Using the spf-schedule-interval command, you can configure the route calculation interval of OSPF. Using the undo spf-schedule-interval command, you can restore the default setting. According to the Link State Database (LSDB), the router running OSPF can calculate the shortest path tree, with itself as the root, and determine the next hop to the destination network according to the shortest path tree. By adjusting the SPF calculation interval, you can decrease the frequency of network changes and unnecessary consumption of bandwidth and router resources. Example To set the OSPF route calculation interval of the Switch 5500 to 6 seconds, enter the following: system-view System View: return to User View with Ctrl+Z. [SW5500]router id 1.1.1.1 [SW5500]ospf [SW5500-ospf]spf-schedule-interval 6 stub Syntax stub [ no-summary ] undo stub
