Step 4 At the VLAN port set to Untag, click the port and choose Tagged.
Note The attached external devices must recognize IEEE 802.1Q VLANs.
Step 5 After each port is in the appropriate VLAN, click Apply.
1.7 Circuits and Timing
This section provides solutions to circuit creation and reporting errors, as well as common timing
reference errors and alarms.
1.7.1 Circuit Transitions to Partial State
Symptom An automatic or manual transition of a circuit from one state to another state results in one of
the following partial state conditions:
• OOS_PARTIAL—At least one of the connections in the circuit is in OOS state and at least one other
connection in the circuit is in IS, OOS_MT, or OOS_AINS state.
• OOS_MT_PARTIAL—At least one connection in the circuit is in OOS_MT state and at least one
other connection in the circuit is in IS, OOS_MT, or OOS_AINS state.
• OOS_AINS_PARTIAL—At least one connection in the circuit is in the OOS_AINS state and at least
one other connection in the circuit is in IS or OOS_AINS state.
Table 1-25 describes the potential cause(s) of the symptom and the solution(s).
Table 1-25 Circuit in Partial State
Possible Problem Solution
During a manual
transition, CTC cannot
communicate with one
of the nodes or one of
the nodes is on a version
of software that does
not support the new
state model.
Repeat the manual transition operation. If the partial state persists, determine
which node in the circuit is not changing to the desired state. Refer to the
“View the State of Circuit Nodes” procedure on page 1-67.
Log onto the circuit node that did not change to the desired state and
determine the version of software. If the software on the node is Software
R3.3 or earlier, upgrade the software. Refer to the Cisco ONS 15327
Software Upgrade Guide for software upgrade procedures.
Note If the node software cannot be upgraded to Software R3.4, the partial
state condition can be avoided by only using the circuit state(s)
supported in the earlier software release.
