Why cannot the OSPF MIB configuration on an S series switch be displayed in a MIB browser

Question: After MIB parameters are configured on a MIB browser and a device, the device fails to connect to the MIB browser and the OSPF MIB configuration cannot be displayed in the browser. What should I do?

Answer: Perform the following operations on the S series switch to solve the problem.
Check whether the connection between the Ethernet interface on the switch and the device where the MIB browser is installed is proper.
Check whether IP address conflict occurs on the network.
If the network is busy, set the interval at which packets are retransmitted to the MIB browser and the retransmission time to smaller values.
Check whether the ospf mib-binding command is executed in the OSPF instance.
Check whether the IP address specified by trap in the snmp-agent target-host trap command is the same as the interface IP address of the MIB browser.
For example, check whether configurations of the following commands are correct. If the configurations are correct and the device where the MIB browser is installed is properly connected to the Ethernet interface on the switch, the browser can correctly display the MIB information.
