1.3.6.1.4.1.9.6.1.83.10.1 - Cisco SG300
« on: January 20, 2014, 05:32:49 PM »
In case it's helpful to anyone, I've modified the bundled definition for 1.3.6.1.4.1.9.6.1.83.10.1.def - the Cisco (-rebranded Linksys) SG300-10:

I added:
Quote
VLnams  1.3.6.1.4.1.9.6.1.101.48.70
Sysdes  1.3.6.1.4.1.9.6.1.101.53.14.1.11.1
These let it read the system description, and the list of configured VLANs
I also changed to:
Quote
Bimage  1.3.6.1.4.1.9.6.1.101.53.14.1.2.1
as the supplied value was giving me the wrong firmware - it stores two firmwares - active and fallback.  However, details of the firmware turn up multiple times (for instance under 1.3.6.1.4.1.9.6.1.101.2 and 1.3.6.1.4.1.9.6.1.101.53.14.1) but not sure how to determine which of the two firmware slots is active.  I guess there's another OID that identifies which of the two slots is set as active, but not sure how to get Nedi to read a different OID depending on which version is active.  It probably is not possible, and probably not hugely important anyway...

I also changed DisPro from LLDP to CDP as with LLDP it was giving me errors on every scan where I had two of these devices connected together, whereas using CDP appears to work fine:
Quote
LLDP sees 64d814604688,gi9 with unusable IP on gi9

Would there be any reason why using LLDP vs CDP for discovery would be preferable?

I also note that these switches advertise themselves via both LLDP and CDP with their MAC address as their device ID, and their name as the System Name, whereas all other devices I have advertise themselves to neighbours with their name as the device ID.  This confuses Nedi as it can't pair up '64d814604688' (for instance) with the actual device.

Fortunately we only have a couple of these!

Tx, I've updated the .def as your suggeststion make sense. LLDP does make sense, if non-Cisco phones are used for example. However this is user-specific and will probably need a configuration option in the future...

As to the ID, I should have a fix in the next version...That System name is at 1.3.6.1.4.1.9.9.23.1.2.1.1.17, right?
Please consider Other-Invoices on your NeDi installation for an annual contribution, tx!

Yes, that looks right.  And the value is "" for OIDs matching the other, normal, devices.
