Re: [Testbed-admins] Debug snmpit
It's a Cisco Catalyst 4506 running Cisco IOS.
It has three line-cards and I checked for the ports to interface assignments of the machines involved in the experiment: they're recognized correctly (Line-Card 2, Port 26 and 37)
mysql> select node_id,type,phys_nodeid from nodes where type like "cisco%";
+-------------+---------------+-------------+
| node_id | type | phys_nodeid |
+-------------+---------------+-------------+
| ctrlswitch1 | cisco2970-ios | ctrlswitch1 |
| expswitch1 | cisco4506-ios | expswitch1 |

Maybe the following output helps:

Debugging SNMP problems in general is a sort of a dark art. :)
'noCreation', the error you got, generally means that you are trying to
access an SNMP object that doesn't exist, and the switch will not
'automatically create' such an object. I've seen this most often when
the index within a table is incorrect - eg. below, it's trying to set
object 2.26 and 2.37 in the portAdminSpeed and portDuplex tables, which
would lead me to guess that one of two thing is the case:
1) Ports 2/26 and 2/37 don't exist in your switch
2) This is on a switch that needs indexing by ifIndex rather than card
and port - eg. an issue of Cisco IOS vs. CatOS - what kind of switch is
this, and if it's a Cisco, did you make sure to follow the bits in the
setup instructions that indicated which OS the switch is running?
The snmpget and snmpwalk command line tools can be useful for diagnosing
these sorts of problems - you can make sure the tables do exist, find
out what the indices look like, etc.
