Do you have a NAM module in your switch which you'll be using as a SPAN destination?. If so, then you can either span from the switch CLI on a per interface basis using 'rmon collection stats owner monitor' or use any RMON application like RTM or NAM's own Traffic Analyzer to do the same.
I know I can use the CLI but I want to use Network Instruments Observer software. In order to analyze traffic on a port or to display switch matrix infos, it uses SPAN to monitor a range of ports you specify (by switching SPAN from one port to the next, etc...). It does this using a script that uses SNMP.
The CLI command is available and the OID is defined in CISCO MIB (Stack) (accorfing CISCO mib files) but gives an error when trying to set source or destination module/port info.
c6sup12-pk2o3sv-mz.121-11b.E does not have the CISCO-STACK-MIB present in the image, hence you're getting 'no such name' error messages. You can verify this by using either http://www.cisco.com/go/mibs (CCO MIB Locator Tool) OR firstname.lastname@example.org automated alias.
