5.4.6.2 SNMP Troubleshooting Help
In configuring and using SNMP, the SNMP server may fail to run properly due to physical
connection failure, wrong configuration, etc. The user should ensure the following:
— 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 are intact and can be verified by ping (use “ping”
command).
— The switch enabled SNMP Agent server function (use “snmp-server enable” command)
— Secure IP for NMS (use “snmp-server securityip” command) and community string (use
“snmp-server community” command) are correctly configured, as if 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).
— During SNMP operation, if the user has any doubt, “show snmp” command can be used to
check for statistics for SNMP traffic, or use “show snmp status” command to check for SNMP
configuration information, or “debug snmp packet” command to enable SNMP debugging
function and view the debug output.
