Thanks for the response.
The cdr link command was not valid but F5 Help showed me that cdr-link was correct.
So status cdr-link showed that the link is up.
Busy was not a valid command but busyout was valid but the only option after that was mis.
Since I couldn't use the busy command I figured I shouldn't use the release command.
I tried to use the test command but the only option for test was firmware.
I know that our system is kinda old so maybe that is the reason for the differences in command options.
Any other ideas?
