Table 6-2: Interface Modes
When changing the interface mode from ’NET’ to ’USR’ and vice versa the clock source setting is
automatically adjusted. For ’NET’ the clock becomes ’master’ and for ’USR’ the clock becomes ’slave’.
You can manually override these default settings of the clock: see the documents Software
Configuration Guide and Command Reference Guide. The next time that the interface mode is
changed the clock source changes back automatically to the default again.
