0300 - TVG Grant Failure

This message indicates that for some card in the system, the grant mechanism (as part of the Multicast Capacity Feature) failed for at least 60 seconds, or more than one time for a 15-second period. A TVG granter failure is defined as a TVG request that completes with a time-out (hardware or software) and/or a status value where the Granter Present bit is not set.

Example

RLGHNCXA21W 09-04-06 11:55:14 EST  EAGLE5 40.3.0-62.15.21
**  0016.0300 ** CARD 1203 SS7ML    TVG Grant Failure
                 INFO:   SCCP  --N---

An alternate output may be displayed when more than one service is denied.

RLGHNCXA21W 00-02-07 11:02:30 EST EAGLE 35.0.0
** 6054.0300  ** CARD 3106  IPLHC   TVG Grant Failure
                 INFO:  +SLAN  --N---

where the "+" sign (INFO: +SLAN --N---) indicates more than one service.

Alarm Level: Major

Recovery

1. Enter the following command to verify the status of the TVG granter:
   rept-stat-card:loc=xxxx:mode=full

   where xxxx is the card location identified in the output.

2. The group ticket voucher status is displayed in these fields:
   • SCCP TVG RESULT (for SCCP messages)
   • SLAN TVG RESULT (for STPLAN messages)
   • INM TVG RESULT (for INM messages)
   • SNM TVG RESULT (for SNM messages)

   Note:

   SNM represents network management messages received by the EAGLE (for example, TFP). INM represents network management events internal event processing.

   Group ticket voucher status output is displayed as a series of these letters:

   G

   Service Granted. Indicates normal system behavior.

   D

   Service Denied. Indicates an overload, but the group ticket voucher hardware and software are working correctly.

   N

   No granter in the system. For GTT or STPLAN traffic, there may be no TSM-SCCP cards or ACMs in the system. If there are TSM-SCCP cards or ACMs in the system, then a serious failure is indicated (hardware or software bug or hardware failure)

   H

   Hardware time-out. Indicates the hardware timed out waiting for a group ticket voucher packet to return. Group ticket voucher packets can be lost when a card is plugged in or booted. This is a serious condition if cards have not been connecting or disconnecting from the IMT.

   S

   Software time-out. No result was ever returned from hardware, indicating a probable hardware failure.

   I

   Invalid result from hardware.
