The configuration on the switch is listed below:
Switch(config)#snmp-server host 2004:1:2:3::2 v1 usertrap
Switch(config)#snmp-server enable traps
4.4.6 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.
4.5 Switch Upgrade
Switch provides two ways for switch upgrade: BootROM upgrade and the TFTP/FTP upgrade
under Shell.
4.5.1 Switch System Files
The system files include system image file and boot file. The updating of the switch is to
update the two files by overwriting the old files with the new ones.
The system image files refer to the compressed files of the switch hardware drivers, and
software support program, etc, namely what we usually called the IMG update file. The IMG
file can only be saved in the FLASH with a defined name of nos.img
The boot file is for initiating the switch, namely what we usually called the ROM update file (It
can be compressed into IMG file if it is of large size.). In the switch, the boot file is allowed to
save in ROM only. Switch mandates the name of the boot file to be boot.rom.
