In this post I will show you how to enable SNMP on a Linksys/Cisco SLM2008. All credits go out for Romain Boissat who made this post:https://chroot-me.in/blog/index.php/blog/35.
First off all you need the download the script from https://chroot-me.in/blog/media/enable_snmp.pl and need to have a Linux box with Perl installed.
The first time I ran the script on Debian 6 I got the following error:
On Debian 6 you have to install the package libwww-perl to get the script working:
apt-get install libwww-perl
After you installed the libwww-perl module you can rerun the script:
quote from https://chroot-me.in/blog/index.php/blog/35:
$ ./enable_snmp.pl <SWITCH IP> Obtaining data from Switch: <SWITCH IP> Administrator Username: [ admin ]: <USER> Administrator Password: [ admin ]: <PASSWORD> Current Body Checksum: <SOME HEXADECIMAL VALUE> Current Header Check Byte: <SOME HEXADECIMAL VALUE> SNMP is currently: DISABLED - WILL ENABLE Both community strings are limited to 15 characters. New read-only community string: [ public ]: <STRING RO> New read-write community string: [ private ]: <STRING RW> New Body Checksum: <SOME HEXADECIMAL VALUE> New Header Check Byte: <SOME HEXADECIMAL VALUE> End - SNMP Should be enabled.
When the above steps ends with an error. You can use the offline method. Just make a backup of your config in the GUI of the SLM2008. Thank copy the .cfg file to a linux box in my case this was Debian. Start the enable_snmp.pl script. Point to the .cfg file. The enable_snmp.pl will generate a new .cfg file.
The next step is to restore the changed config to the SLM2008 switch. Open the GUI and upgrade the configuration with the new “snmpenabled” config via Admin – Save configuration – Upgrade:
With snmpwalk you can verify if the new SNMP setup is working:
snmpwalk -c public 192.168.123.253 -v 2c
You can use Cacti to graph the switchports. In the screenshot below you see a running vMotion of a small VM:

Cool, I have a SLM2005. Almost similar. I will try if it works on that device also.
it does not, unfortunately (just tried …)
I just enabled snmp on my SLM2008 via the online method.
Just what I needed from the beginning when I bought the switch some years ago.
Good work from Romain Boissat.
Some simple mods will make the script work for SLM2005 instead.
Change the following:
Lines 44 and 65: 0x1F0 to 0x1D9
Lines 45 and 66: 0x1F7 to 0x1E0
Lines 47 and 67: 0x20C to 0x1F5
The script should work fine after that. Just the data addresses were changed between models, adjust for that and everything is good.
