Issue/Introduction

All the snmpv3 profiles are lost after upgrade to Spectrum 10.4.1.
We saw the same issue at another site and had to manually re-create them but here the manual task is too large.

How can we recover them?

Environment

Release : 10.4.1

Component : Spectrum Core / SpectroSERVER

Resolution

Dump the v3 profiles (action code 0x10331 against the vnm model). The profiles show in VNM.OUT.

Try logging into Spectrum CLI
1. log into SpectroSERVER via Bash shell or similar
2. nav to /vnmsh
3. run the following commands:
./connect

find the vnm model_handle

./show models | grep -i vnm
./update action=0x10331 mh=<vnm model_handle from previous command>

That's sufficient to recover the profiles.
