Since the update to CnMaestro 3.0.3-r18 the substring search for the switch ports does not work anymore. I reported this problem a few months ago, after that it was fixed, now this seems to have been reverted.
Switch Groups > Hall 550 > Switch Ports
Search: -021 > Shows a hit in the Description column, but not the entries in the Port column.
Search: h550-cmb-ex2028-021 > Also shows the hits in the Port column.
It would be helpful if ‘Search’ would also show hits of substrings in the Port column. As I said, this already worked.
