That would be the CampusManager system from Bradford, I presume?

Your message truncated the output during the error from the bare
"snmpwalk" command, so I assume there was nothing important
after that.
The information you are getting there is simply the basic 'system' group.
A common configuration of SNMP servers "as shipped" will be to report
this information and nothing else. It's then up to the local network
admin to decide how much to open up to general view, and/or what
local information to make available.
This is described in the FAQ entry
I can see the system group, but nothing else. Why?
The other issue is that you are walking the 'mib-2' group
(i.e. the officially defined management information).
You won't be picking up any enterprise-specific information
(which is where a lot of the useful stuff lies).
More recent versions of the Net-SNMP snmpwalk command
will default to showing the whole lot, but Bradford Network
ship a relatively old setup, which doesn't.
This is described in the FAQ entry
Why can't I see values in the <ENTERPRISE> tree?

Try adding ".1" to the end of the snmpwalk command.
That will walk the whole tree (including enterprise-specific)
and show everything that is currently accessible.
You could also try logging onto the CampusManager box,
find the 'snmpd.conf' file, and add the line
rocommunity aardvark
You could then run
snmpwalk -v 2c -c aardvark 10.3.1.92 .1
which would show you *everything* that the agent knows.
(Replace "aardvark" with your preferred internal community name)
