2.7.244 LPBKFACILITY (G1000)
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: G1000
A Loopback Facility condition for the G1000 object occurs when a software facility (line) loopback is
active for a port on the reporting G-Series Ethernet card.
For information about troubleshooting Ethernet circuits with loopbacks, refer to the
“1.5 Troubleshooting Ethernet Circuit Paths With Loopbacks” section on page 1-68.
Caution CTC permits loopbacks on an in-service (IS) circuit. Loopbacks are Service-Affecting (SA).
Note For more information about Ethernet cards, refer to the Cisco ONS 15454 and
Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration Guide.
Clear the LPBKFACILITY (G1000) Condition
Step 1 Complete the “Clear Other Electrical Card or Ethernet Card Loopbacks” procedure on page 2-277.
Step 2 If the condition does not clear, log into the Technical Support Website at
