SNR S2940-8G-v2 Switch Configuration Guide
Basic Switch Configuration
• 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.
2.5 Switch Upgrade
Switch provides two ways for switch upgrade: BootROM upgrade and the TFTP/FTP upgrade
under Shell.
2.5.1 Switch System Files
The system files includes system image file and boot file. The updating of the switch is to update
the two files by overwrite the old files with the new ones.
The system image files refers to the compressed files of the switch hardware drivers, and
software support program, etc, namely what we usually call 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 call the ROM update file (It can
be compressed into IMG file if it is of large size). In switch, the boot file is allowed to save in ROM
only. Switch mandates the name of the boot file to be
boot.rom .
The update method of the system image file and the boot file is the same. The switch supplies
the user with two modes of updating:
1. BootROM mode;
2. TFTP and FTP update at Shell mode.
This two update method will be explained in details in following two sections.
2.5.2 BootROM Upgrade
There is one method for BootROM upgrade: TFTP which can be configured at BootROM com-
mand.
The upgrade procedures are listed below:
Step 1:
As shown in the figure, a PC is used as the console for the switch. A console cable is used
to connect PC to the management port on the switch. The PC should have TFTP server software
installed and has the image file required for the upgrade.
Step 2:
Press 'Ctrl+b' on switch boot up until the switch enters BootROM monitor mode. The operation
result is shown below:
