Missing Layer 2 connectivity after installation of fixpack 3

Technote (troubleshooting)

This document applies only to the following language version(s):



CDPLayer agent discovered layer 2 connectivity was in the GUI Hopview before installation
of fixpack 3, but missing once fixpack 3 was installed.


Some layer 2 connectivity can still exist.


For any stitcher that uses workingEntities.interfaceMapping, a new table in fixpack 3 must have the correct schema in DiscoSchema.DOMAIN.cfg.

Failing stitchers could include:







Diagnosing the problem

cd $NCHOME/etc/precision

# grep workingEntities.interfaceMapping DiscoSchema*

DiscoSchema.cfg:create table workingEntities.interfaceMapping
DiscoSchema.cfg: workingEntities.interfaceMapping
DiscoSchema.SCOM39.cfg:create table workingEntities.interfaceMapping
DiscoSchema.SCOM39.cfg: workingEntities.interfaceMapping

Resolving the problem

Perform the above 'grep' command, and if you find that you do not have

workingEntities.interfaceMapping in the domain specific version of DiscoSchema.DOMAIN.cfg file, then some fixpack 3 post installation instructions may have been missed.

Review $NCHOME/log/install/Configuration.log for instructions:
