uMate Failed to Establish an SNMP Connection in E9000 PMI Because Port 161 Is Disabled on the Firewall

Publication Date:  2019-04-24 Views:  37 Downloads:  0
Issue Description

uMate is used to perform a preventive maintenance inspection (PMI) on two E9000 servers. The PMI fails in less than one minute after the PMI starts, and the error message "SNMP config error or unsupported server, please check the network, snmp settings and the system configuration." is displayed.

The customer's uMate SNMP uses the default configuration as follows:

1. If the network between the SNMP client and the HMM is disconnected, check whether SNMP is disabled on the HMM.

2. If a firewall exists between the SNMP client and the HMM, check whether port 161 is disabled.

Handling Process

1.1 The user can log in to the HMM, and the SNMP client is integrated in the uMate package. The network connection between the SNMP client and the HMM is normal.

1.2 uMate uses SNMPv3. By default, SNMPv3 is enabled on the HMM. In addition, there is no command for disabling SNMPv3 or for checking the SNMPv3 status. Therefore, SNMPv3 is enabled on the HMM. (You can run the command shown in the following figure to check the status of SNMPv1 and SNMPv2. However, there is no command to check the status of SNMPv3.)

1.3 Use the snmpget open-source tool to send packets to check whether SNMP port 161 is disabled by the firewall.

Log in to the HMM WebUI, choose System Management > System Settings > Security Policy, and check the SNMPv3 settings. As shown in the following figure, SNMPv3 uses MD5 and AES.

Switch to the uMate directory FusionServer Tools-uMate-Win-V137\tools\snmptool, enter the cmd command, and press Enter.
