mikeatcomtech - Thanks for posting your question on the forum.
The command should be available on non-SBC code as well. It was introduced in A5.02 but was modified in R10.8 to remove the keyword "ip" from the command.
What firmware are you running? Try removing the keyword "ip"and seeing if it will take it then.
If you are still having issues, please reply to this post with the firmware you are running and a screenshot of what you are seeing.
I was on Ver 18 fimware. I upgraded to R10.9.4 and I am now able to enter the commands. Thank you!
