Snmp Troubleshooting - Planet XGS3-42000R User Manual

XGS 3-42000R(config)#snmp-server community rw privat e
XGS 3-42000R(config)#snmp-server community ro public
XGS 3-42000R(config)#snmp-server securityip 2004:1:2: 3::2
The NMS can use private as the community string to access the Chassis Switch with read-write permission,
or use public as the community string to access the Chassis Switch with read-only permission.
Scenario 6: NMS will receive Trap messages from the Chassis XGS3-42000R(Note: NMS may have
community string verification for the Trap messages. In this scenario, the NMS uses a Trap verification
community string of dcstrap).
The configuration on the switch is listed below:
XGS 3-42000R(config)#snmp-server host 2004:1:2:3::2 v1 dcstrap
XGS 3-42000R(config)#snmp-server enable traps

4.4.6 SNMP Troubleshooting

When users configure the S NMP, 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 protoc ol is Up (use the "show interface" command), and the connection
between the Chassis Switch and host can be verified by ping (us e "ping" command).
 The Chassis Switch enabled S NMP 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 t hem 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 cent er.
