82• Perform SNMP Get operation on the NMS to obtain the value of the MIB node.Alarm group configuration exampleNetwork requirementsAs shown in Figure 31, Agent is connected to a console terminal through its console port and to an NMSacross Ethernet.Do the following:• Connect Ethernet 1/0/1 to the FTP server. Gather statistics on traffic of the server on Ethernet1/0/1 with the sampling interval being five seconds. When traffic is above or below the thresholds,Agent sends the corresponding traps to the NMS.• Execute the display rmon statistics command on Agent to display the statistics, and query thestatistics on the NMS.Figure 31 Network diagramConfiguration procedure# Configure the SNMP agent, and make sure that the SNMP settings are the same as on the NMS. Thisexample sets the SNMP version to SNMPv1, read community to public, write community to private, andthe trap destination to 1.1.1.2, the IP address of the NMS. system-view[Sysname] snmp-agent[Sysname] snmp-agent community read public[Sysname] snmp-agent community write private[Sysname] snmp-agent sys-info version v1[Sysname] snmp-agent trap enable[Sysname] snmp-agent target-host trap address udp-domain 1.1.1.2 params securitynamepublic# Configure RMON to gather statistics for interface Ethernet 1/0/1.[Sysname] interface ethernet 1/0/1[Sysname-Ethernet1/0/1] rmon statistics 1 owner user1[Sysname-Ethernet1/0/1] quit# Create an RMON alarm entry so when the delta sampling value of node 1.3.6.1.2.1.16.1.1.1.4.1 exceeds100 or is lower than 50, event 1 is triggered to send traps.[Sysname] rmon event 1 trap public owner user1[Sysname] rmon alarm 1 1.3.6.1.2.1.16.1.1.1.4.1 5 delta rising-threshold 100 1falling-threshold 50 1# Display the RMON alarm entry configuration.
