If I set the parameter with '-' at the beginning, the next command to this parameter with TAB shows an error
For example
vyos@vyos# set policy route-map TEST rule 10 set metric Possible completions: <+/-metric> Add or subtract metric <0-4294967295> Metric value [edit] vyos@vyos# set policy route-map TEST rule 10 set metric -10 [edit] vyos@vyos# set policy route-map TEST rule 10 set metric [TAB] cli-shell-api: invalid option -- '1' cli-shell-api: invalid option -- '0' Possible completions: <+/-metric> Add or subtract metric <0-4294967295> Metric value -10 [edit]
