I want to manage a wireless lan adaptor which is

WLI-TX4-AG300N.
However, it's not in the list of default device templates.

So I want to add the templates, but to do so, I need to have  sysOID.

I don't really know what it is, so I want to use query for it, but

for query I have to have snmp authentification.

How can I get the sysOID for the device?

If anyone knows how, please help me!

Thank you.
