For example, to set the service state of the IP link, iplink1, to IS, enter the following command:
set-iplnk:iplink1:IS

set-iplnk:mgcplnk1:IS::confirm
You can verify that the selected IP link is in the proper service state by performing the procedure in the
“Retrieving the Service State for IP Links” section on page 37.
