B.3.2 Port and Cross-Connect Service State Transitions
Table B -5 lists the port and cross-connect service state transitions. Port states do not impact
cross-connect states with one exception. A cr oss-connect in the Unlocked-disabled,aut omaticInService
service state cannot transition autonomously into the Unlocked-enabled service state until the parent port
is Unlocked-enabled.
The following ports do not support all of the service states listed in Table B-5 :
E-Series Ethernet ports do not support service states; thes e ports are either enabled or disabled.
FC_MR-4 ports support the Unlocked-enabled; Locked-enabled,disabled; and
Locked-enabled,maintenance service states; they do not support the
Unlocked-disabled,automaticInService service state.
