Great. Thank you very much for your help Dave. I am able to perform snmpget/snmpwalk with the Cisco switch to collect CPU & Memory utilization without reinstalling anything. The trick was to perform an snmpwalk on a specific table to find out the additional extensions after the published OID.

How are you trying to retrieve the Cisco-specific information?
What commands are you giving?

No - almost certainly not.

Neither do we - that's really a question for the Cisco support people,
not us. But I'd be rather surprised if they were using the Net-SNMP
code, rather than a home-grown embedded system. And I'd be gobsmacked
if they expected you to re-compile the agent yourself.
No - either the agent already supports the information you're after,
and the problem is just in asking for it correctly (most likely), or
you might need to install an updated version of the switch firmware
(least likely), or the information is not available at all (medium
to low likely).

No - you shouldn't need to reinstall anything.
If you know the numeric OIDs for the information you are after,
you can use those directly. Otherwise, all you need to do is
install the new MIB files and configure the Net-SNMP tools to
load them. You don't need to reinstall the whole suite.
See the FAQ entry
How do I add a MIB to the tools
for more details.
