Alarm Procedures
Clear the LP-PLM Alarm
Step 1 If the alarm does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC
(1-800-553-2447) in order to report a Service-Affecting (SA) problem.
2.7.172 HP-PLM
Default Severity: Major (MJ), Service-Affecting (SA)
SDH Logical Object: VCTRM-LP, VCMON-LP
A Payload Label Mismatch VT Layer alarm raises when the content of the V5 byte in the SDH overhead
is inconsistent or invalid. HP-PLM occurs when ONS 15310-MA SDHs interoperate with equipment
that performs bit-synchronous mapping for E1 signal. The node uses asynchronous mapping.
Clear the HP-PLM Alarm
Step 1 Verify that your signal source matches the signal allowed by the traffic card. For example, the alarm will
occur if your signal source uses VT6 or VT9 mapping, because this is not supported by a 15310-MA
SDH CTX, E1-21/DS3-E3-3, or E1-63/DS3-E3-3 card.
Step 2 If the signal source matches the card, verify that the SDH VC path originator is sending the correct VC
label value. You can find the SDH VC path originator using circuit provisioning steps.
Step 3 If the alarm does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC
(1-800-553-2447) in order to report a Service-Affecting (SA) problem.
2.7.173 PORT-MISMATCH
Default Severity: Major (MJ), Service-Affecting (SA)
SDH Logical Object: CE-MR-6
The Pluggable PORT-MISMATCH alarm applies to CE-MR-6 Ethernet cards.
The alarm indicates either of the following:
• The provisioned payload, speed, or duplex configured on the port does not match that of the SFP
plugged into the port.
• A non-supported SFP is plugged into the port.
