CNA error

Unanswered Question


I have CNA 4 installed and when I try and modify a port setting from the front panel view I am greeted by an error dialog.

(Error: Modify Port Settings


The switches (2950T-24/2950G-24-EI) all meet the minimum IOS version and this wasn't a problem in v3.1

The error from the log file is

com.cisco.cpnm.frmwrk.gen.dynamic.InstanceNotFoundException: com.cisco.cpnm.features.defn.port.data.ConnectionTypeData

at com.cisco.cpnm.legacy.networkdata.CommonSwitch.getInstance(CommonSwitch.java:1699)

at com.cisco.cpnm.frmwrk.gen.wd.WDWidget$2.run(WDWidget.java:1160)

Is it something with my setup or a known issue that I am seeing?
