An issue was submitted which causes the App to crash. The problem takes place when removing a connection from a list of multiple cables connecting 2 devices. When a user selects the bottom cable for removal the App crashes.
It's not ideal but please remove all the cables connecting the 2 devices from the top down first. This will allow for the safe removal of all the cables. You'd be able to add new connections afterwards. Version 1.68 fixes this issue.
A bug was found with the following commands:
ip nat pool WORD A.B.C.D A.B.C.D netmask A.B.C.D
ip nat pool WORD A.B.C.D A.B.C.D prefix-length <1-32>
Please use the command below until version 1.68 is released.
r1(config)# ip nat inside source list <1-199> interface fastethernet PORT/PORT overload
We apologize for the inconvenience and appreciate your patience.
