2.7.197 LMP-UNALLOC
Step 2 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.
2.7.197 LMP-UNALLOC
The LMP Data Link Unallocated condition is raised when the TCC2/TCC2P receives an LMP link
summary or channel status message reporting that the data link as unallocated for data traffic. The
condition clears when the data link is allocated and sends an LMP link summary or channel status
message to this effect. If a data link has the LMP-UNALLOC alarm raised against it, this should suppress
all other alarms on the client port, since the far-end node is not using the errored port. (Consequently
you do not have to clear any alarms on the far-end node's unused port.)
LMP-UNALLOC is part of an alarm hierarchy that includes the
"LMP-SF" alarm on page
LMP-SD are suppressed. If LMP-SF is raised, it suppresses LMP-SD. LMP-SF and LMP-UNALLOC
both suppress near-end LOS-type DWDM client alarms, but LMP-SD does not.
In most cases, this condition is an informational notice at the near-end node that the far-end port is not
being utilized. If, however, the far-end port should be allocated for traffic, log into the Technical Support
Website at http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.
2.7.198 LOA
The Loss of Alignment on a VCG is a VCAT member alarm. (VCAT member circuits are independent
circuits that are concatenated from different time slots into a higher-rate signal.) The alarm occurs when
members of a VCG travel over different paths in the network (due to initial operator provisioning or to
protection or restoration events) and the differential delays between the paths cannot be recovered by
terminating hardware buffers.
This alarm occurs only if you provision circuits outside of CTC, such as by using TL1.
Note
Clear the LOA Alarm
In network view, click the Circuits tab.
Step 1
Click the alarmed VCG and then click Edit.
Step 2
Step 3 In the Edit Circuit window, view the source and destination circuit slots, ports, and STSs.
Step 4 Identify whether the STS travels across different fibers. If it does, complete the
