Re: apa topology error

Hello Jose


The error suggests a problem with a filter.


I think we need to run the ovet_demandpoll.ovpl -d <device> command and review the output information. We need to make sure we are creating the correct filter.


Also, I recommend checking and testing these filters by running the ovet_topofilter.ovpl


Hope this information helps

Re: apa topology error

Hi, thanks for your reply.


I did not build any filter. Using default TopoFilters.xml.


ovet_demandpoll.ovpl for others devices works fine.


BTW, where ovet_topofilter.ovpl lives ?


TIA and regards

Re: apa topology error



Also, try using an IP address filter for this specific node under: /etc/opt/OV/share/conf/nnmet/topology/filter/TopoFilters.xml




Try adding an underscore (|\_) to the appropriate section of the TopoFilters.dtd
