Collecting CPU & Memory Utilization on Cisco Catalyst 6500

Hi All,

I would like to poll Cisco Catalyst switch 6500, running IOS 12.1 (11b), 
for CPU & Memory utilization.  I am using net-snmp v5.1.2 on Redhat FC4 to 
perform snmpget/walk to the switch.  I found out that the information I 
want to collect are in CISCO-PROCESS-MIB and CISCO-MEMORY-POOL-MIB.  I am 
able to get MIB-II information from the switch, but nothing else.  I have 
the following questions:

1) Do I have to reinstall the snmp agent on the Catalyst 6500 with the 
option "./configure --with-mib-modules=xxxx"?  I really don't know if the 
snmp agent running on the Cisco switch is the same as say Solaris or 
Window.

2) Maybe I have to reinstall net-snmp on the client Redhat FC4 so that it 
includes the Cisco MIBs?  In general, do I need to reinstall net-snmp on 
the client side to include the enterprise MIBS or it only needs to be done 
at the agent side?

Thanks in advance for your help.
