I am struggling to understand the snmptranslate command

I picked ipSystemStatsInDiscards as my test OID because my family says 
that my home LAN is performing poorly.  So I thought this would be a 
golden opportunity to learn something about SNMP.  Alas, I'm not doing a 
very good job starting out.

[jeffs@black ~]$ snmptranslate -Ib ipSystemStatsInDiscards
IP-MIB::ipSystemStatsInDiscards
[jeffs@black ~]$ snmptranslate -Of -Ib ipSystemStatsInDiscards
.iso.org.dod.internet.mgmt.mib-2.ip.ipTrafficStats.ipSystemStatsTable.ipSystemStatsEntry.ipSystemStatsInDiscards
[jeffs@black ~]$ snmptranslate -On IP-MIB::ipSystemStatsInDiscards
.1.3.6.1.2.1.4.31.1.1.17
[jeffs@black ~]$ snmptranslate .1.3.6.1.2.1.4.31.1.1.17
IP-MIB::ipSystemStatsInDiscards

So far, so good, I guess.  I'm not sure why it uses IP-MIB:: but since 
the translation is bijective, I guess there's a good reason.  However, 
the following doesn't work and I don't understand why not.

[jeffs@black ~]$ snmptranslate 
.iso.org.dod.internet.mgmt.mib-2.ip.ipTrafficStats.ipSystemStatsTable.ipSystemStatsEntry.ipSystemStatsInDiscards
No log handling enabled - turning on stderr logging
.iso.org.dod.internet.mgmt.mib-2.ip.ipTrafficStats.ipSystemStatsTable.ipSystemStatsEntry.ipSystemStatsInDiscards: 
Unknown Object Identifier (Sub-id not found: iso -> iso)

Is this problem the reason why snmpget doens't work?

[jeffs@black ~]$ snmpget -v 2c -Le -c puBlIc localhost 
.1.3.6.1.2.1.4.31.1.1.17
IP-MIB::ipSystemStatsInDiscards = No Such Object available on this agent 
at this OID
[jeffs@black ~]$      

Here are some other things I have tried which still don't work the way I 
guess I expect them to.

[jeffs@black ~]$ snmpget -v 2c -c public localhost system.sysDescr.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux black 2.6.15-1.2054_FC5 #1 Tue 
Mar 14 15:48:33 EST 2006 i686
[jeffs@black ~]$ snmpget -v 2c -c public localhost SNMPv2-MIB::sysDescr
SNMPv2-MIB::sysDescr = No Such Instance currently exists at this OID
[jeffs@black ~]$ snmptranslate -Of -Ib sysDescr
.iso.org.dod.internet.mgmt.mib-2.system.sysDescr
[jeffs@black ~]$ snmptranslate -On -Ib sysDescr
.1.3.6.1.2.1.1.1
[jeffs@black ~]$ snmpget -v 2c -c public localhost SNMPv2-MIB::sysDescr.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux black 2.6.15-1.2054_FC5 #1 Tue 
Mar 14 15:48:33 EST 2006 i686
[jeffs@black ~]$ snmpget -v 2c -c public localhost 
.iso.org.dod.internet.mgmt.mib-2.system.sysDescr.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux black 2.6.15-1.2054_FC5 #1 Tue 
Mar 14 15:48:33 EST 2006 i686
[jeffs@black ~]$ snmptranslate -Td 
.iso.org.dod.internet.mgmt.mib-2.ip.ipInDiscards.0
No log handling enabled - turning on stderr logging
.iso.org.dod.internet.mgmt.mib-2.ip.ipInDiscards.0: Unknown Object 
Identifier (Sub-id not found: iso -> iso)
[jeffs@black 
~]$                                                                                                  

[jeffs@black ~]$ snmpget -v 2c -c public localhost .1.3.6.1.2.1.1.1
SNMPv2-MIB::sysDescr = No Such Instance currently exists at this OID
[jeffs@black ~]$ snmpget -v 2c -c public localhost .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux black 2.6.15-1.2054_FC5 #1 Tue 
Mar 14 15:48:33 EST 2006 i686
[jeffs@black ~]$     

Hopefully, I am running into a simple stupid problem with a simple 
answer.  Can somebody please tell me what that problem is?

 [jeffs@black ~]$ snmptranslate -V
NET-SNMP version: 5.3
[jeffs@black ~]$ cat /etc/redhat-release
Fedora Core release 5 (Bordeaux)
[jeffs@black ~]$     


Thank you
