1.2.4.6 SNMP Troubleshooting

When users configure the SNMP, the SNMP server may fail to run properly due to

physical connection failure and wrong configuration, etc. Users can troubleshoot the

problems by following the guide below:

 Good condition of the physical connection.

 Interface and datalink layer protocol is Up (use the “show interface” command), and

the connection between the switch and host can be verified by ping (use “ping”

command).

 The switch enabled SNMP Agent server function (use “snmp-server” command)

 Secure IP for NMS (use “snmp-server securityip” command) and community string

(use “snmp-server community” command) are correctly configured, as any of them

fails, SNMP will not be able to communicate with NMS properly.

 If Trap function is required, remember to enable Trap (use “snmp-server enable traps”

command). And remember to properly configure the target host IP address and

community string for Trap (use “snmp-server host” command) to ensure Trap

message can be sent to the specified host.

 If RMON function is required, RMON must be enabled first (use “rmon enable”

command).

 Use “show snmp” command to verify sent and received SNMP messages; Use “show

snmp status” command to verify SNMP configuration information; Use “debug snmp

packet” to enable SNMP debugging function and verify debug information.

If users still can’t solve the SNMP problems, Please contact our technical and service

center.
