Switch port/service description with wizard

Hi !
Usually, using the "Configuration Wizard: Network Switch / Router Step1" , in the Monitoring Options, I can monitor using : port's description and I get the description the Network admin wrote in the switch configuration ; something like : "TenGigabitEthernet-0/0 A-S50-AS Bandwidth"
I noticed the wizard do not fetchg that information when I configure a Dell switch S4248 with OS version 10.
Am I forgetting something in the configuration option ?
Is the wizard renowned to be working properly with OS10 ? or is it not OS "specific" and the problem might be on the switch side ?
Thank you !

Hi Mick,
The port description is most likely device dependent. So what you would need to do is get
the MIB file(s) for that device and put them in: /usr/share/snmp/mibs
Then in /usr/share/snmp edit snmp.conf (or create it if it doesn't exist) and add the MIB filenames
to it. Here's one I did for some Linksys mibs:
Code: Select all
[root@localhost snmp]# cat snmp.conf
mibs +LINKSYS-MODEL-MIB
mibs +LINKSYS-MIB
Thanks

Hi gsmith,
It does not work for me at the time.
I contacted Dell support to get the MIB files, unzipped them and put those files in the directory you specified, added all the file names to snmp.conf , tried with the name as it is with the .mib extension, without the .mib extension, with the "mibs +" as you wrote in your example and without.
We are using snmp v2 , doest it matter ?
I will try to manually create a service to see if I can get a descrition from the switch.
are there other things I could try ?
Thanks

Hi,
Here is an excellent tutorial describing what I was trying to explain to you, but
it's a lot clearer.
http://net-snmp.sourceforge.net/tutoria ... tions.html
Another thing to check is to make sure "TenGigabitEthernet-0/0 A-S50-AS Bandwidth" is actually in the MIB files
you have. There are online MIB browsers and free downloadable MIB browsers that will let you load up some MIB files
and then do a text search for you.
Let me know how you do.
Thanks
