Administrative and Service States with Soak Time for Ethernet and SONET/SDH Ports
Administrative and Service States with Soak Time for Ethernet and SONET/SDH
Ports
The CE-1000-4 card supports the administrative and service states for the Ethernet ports and the
SONET/SDH circuit. For more information about card and circuit service states, refer to the
“Administrative and Service States” appendix in the Cisco ONS 15454 Reference Manual or the
Cisco ONS 15454 SDH Reference Manual.
Ethernet ports can be set to the In-Service, Automatic In-Service (IS,AINS) administrative state.
IS,AINS initially puts the port in the Out-of-Service and Autonomous, Automatic In-Service
(OOS-AU,AINS) state. In this service state, alarm reporting is suppressed, but traffic is carried and
loopbacks are allowed. After the soak time passes, th e port changes to In-Service and Normal (IS-NR) .
The default soak time is eight hours and zero minutes. The user can also configure the AINS soak time
under the Provisioning tab > Ether Ports tab or under the Provisioning tab > POS Ports tab. The user can
view the AINS soak time and the time remaining until IS under the Maintenance tab > AINS Soak tabs.
Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions
tab or by using the TL1 RTRV-COND command.Two Ethernet port alarms/conditions, CARLOSS and
TPTFAIL, can prevent the port from going into service. This occurs even though alarms are suppressed
when a CE-1000-4 circuit is provisioned with the Ethernet ports set to the IS,AINS state, because the
CE-1000-4 link integrity function is active and ensures that the links at both ends are not enabled until
all SONET/SDH and Ethernet errors along the path are cleared. If the link integrity function keeps the
end-to-end path down, both ports will have at least one of the two conditions needed to suppress the
AINS-to-IS transition. Therefore, the ports will remain in the AINS state with alarms suppressed.
ESM also applies to the SONET/SDH circuits of the CE-1000-4 card. If the SONET/SDH circuit is set
up in IS,AINS state and the Ethernet error occurs before the circuit transitions to IS, then link integrity
will also prevent the circuit transition to the IS state until the Ethernet port errors are cleared at both
ends. The service state will be OOS-AU,AINS as long as the administrative state is IS,AINS. When there
are no Ethernet or SONET errors, link integrity enab les the Ethernet port at each end. Simultaneously,
the AINS countdown begins as normal. If no additional conditions occur during the time period, e ach
port transitions to the IS-NR state. During the AINS countdown, the soak time remaining is available in
CTC and TL1. The AINS soaking logic restarts from the beginning if a condi tion appears again during
the soak period.
A SONET/SDH circuit provisioned in the IS,AINS state remains in the initial Out-of-Service (OOS)
state until the Ethernet ports on each end of the circuit transition to the IS-NR state. The SONET/SDH
circuit transports Ethernet traffic and counts statistics when link integrity turns on the Ethernet port,
regardless of whether this AINS-to-IS transition is complete.
RMON and SNMP Support
The CE-1000-4 card features remote monitoring (RMON) and simple network management protocol
(SNMP) that allows network operators to monitor the health of the network with a network management
system (NMS). The CE-1000-4 uses ONG RMON. ONG RMON contains the statistics, history, alarms,
and events MIB groups from the standard RMON MIB. A user can access RMON threshold provisionin g
through TL1 or CTC. For RMON threshold provisioning with CTC, refer to t he Cisco ONS 15454
Procedure Guide or the Cisco ONS 15454 SDH Procedure Guide.
