Cisco ONS 15454 SDH Circuit Status
Status
Definition/Activity
CREATING
CTC is creating a circuit.
DISCOVERED
CTC created a circuit. All components are in place and a complete
path exists from the circuit source to the circuit destination.
DELETING
CTC is deleting a circuit.
PARTIAL
A CTC-created circuit is missing a cross-connect or network
span, a complete path from source to destination(s) does not exist,
or the MAC address of the site change occurred on one of the
circuit nodes and the circuit is in need of repair. (The chassis
stores the node MAC address.)
In CTC, circuits are represented using cross-connects and
network spans. If a network span is missing from a circuit, the
circuit status is PARTIAL. However, a PARTIAL status does not
necessarily mean a circuit traffic failure has occurred, because
traffic might flow on a protect path.
Network spans are in one of two states: up or down. On CTC
circuit and network maps, up spans are shown as green lines, and
down spans are shown as gray lines. If a failure occurs on a
network span during a CTC session, the span remains on the
network map but its color changes to gray to indicate the span is
down. If you restart your CTC session while the failure is active,
the new CTC session cannot discover the span and its span line
will not appear on the network map.
Subsequently, circuits routed on a network span that goes down
will appear as DISCOVERED during the current CTC session, but
they will appear as PARTIAL to users who log in after the span
failure.
DISCOVERED_TL1
A TL1-created circuit or a TL1-like CTC-created circuit is
complete. A complete path from source to destination(s) exists.
PARTIAL_TL1
A TL1-created circuit or a TL1-like CTC-created circuit is
missing a cross-connect, and a complete path from source to
destination(s) does not exist.
CONVERSION_PENDING
An existing circuit in a topology upgrade is set to this state. The
circuit returns to the DISCOVERED state once the topology
upgrade is complete. For more information about topology
upgrades, see the “SDH Topologies and Upgrades” chapter in the
Cisco ONS 15454 SDH Reference Manual
