LPBKFACILITY (TRUNK)
Default Severity: Not Alarmed (NA), Non-Service Affecting (NSA)
Logical Object: TRUNK
A Loopback Facility condition on MXP, TXP, GE-XP, 10GE-XP, and ADM-10G card trunk ports indicates
that there is an active facility (line) loopback on the port. For this condition to be present, the administrative
state is OOS,MT (or Locked,maintenance).
For information about troubleshooting these circuits with loopbacks, refer to the Troubleshooting MXP, TXP,
XP, or ADM-10G Circuit Paths With Loopbacks, on page 7 section.
CTC permits loopbacks on an in-service (IS) circuit. Loopbacks are service-affecting.
Caution
Clear the LPBKFACILITY (TRUNK) Condition
SUMMARY STEPS
1. Complete the Clear an MXP, TXP, GE-XP, 10GE-XP, and ADM-10G Card Loopback Circuit, on page
455 procedure.
DETAILED STEPS
Complete the Clear an MXP, TXP, GE-XP, 10GE-XP, and ADM-10G Card Loopback Circuit, on page 455 procedure.
If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/c/en/us/support/index.html
for more information or call Cisco TAC (1 800 553-2447).
LPBKTERMINAL (ESCON)
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
Logical Object: ESCON
The LPBKTERMINAL (ESCON) condition occurs on a TXP_MR_2.5G or TXPP_MR_2.5G card PPM (SFP)
provisioned for FICON1G or FICON 2G line speed when there is a terminal loopback active on the card.
For information about troubleshooting these circuits with loopbacks, refer to the Troubleshooting MXP, TXP,
XP, or ADM-10G Circuit Paths With Loopbacks, on page 7 section.
