When ever i try to use a command that has more parameters the CLI automatically introduces a space character "ASCI Hex 20" between the 65th and 66th character. For the purpose of this case study i'll give a example of command:
nat server 20 protocol tcp global 100.100.100.100 smtp inside 200" ".200.200.200
I have indicated the space character introduced by the CLI by using " " in the command line above.
As the command can still be applied after the space character is introduced, without any errors we can assume that this display bu doesn't affect device operation and thus can be ignored.
This issue is caused by a display BUG that does not affect normal device operation.
