Problem Description

SNMP traps will not be transmitted when TCC-B/XTC-B is active. This will only occur on ONS software releases 2.35 and 4.14. This issue is tracked by CSCee55443. No other releases are affected by this issue.

Background

This issue occurs as a result of a communications failure between the alarm subsystem and the SNMP subsystem within the TCC/XTC card, due to the use of an inappropriate network interface for transmitting intra-card UDP packets. While SNMP traps will not be transmitted in this situation, SNMP gets will continue to function normally.

Problem Symptoms

SNMP traps are not transmitted by the NE. This can be checked via CTC or TL1 by cross-referencing the timestamp of the last alarm trap received by an NMA with the timestamp of the newest alarm reported by the NE.

Workaround/Solution

With Releases 2.3.5 and 4.1.4, this issue can occur whenever TCC-B or XTC-B is active. To avoid the issue in those releases, make the TCC-A or XTC-A active. This issue is resolved in Releases 4.1.5 and 4.1.6 (available 9/30/2004). Release 4.1.6 contains all Release 4.1.4 software changes, plus the change for this issue. Release 4.1.6 does not include changes implemented first in Release 4.1.5. To upgrade to the release that contains the greatest number of changes, use Release 4.1.5. To upgrade to a release that is compatible with CTM Release 4.7.1 and contains this specific change, use Release 4.1.6.

Note: Release 4.1.6 is an out of sequence release.
