Products

• CA eHealth

Issue/Introduction

Unable to discover SNMPv3 devices.

Environment

eHealth 6.3.2.11 on windows 2008R2

Cause

When trying to verify Brassd communication using getone command, it's giving error port 4747 unreachable.

Resolution

Even though there is no firewall between eHealth server and target SNMPv3 device and also windows firewall is turned off on eHealth server,but still we are getting port 4747 unreachable.

=> Verify whether the file C:\Windows\System32\drivers\etc\services is having the below two lines in it for brassd to listen on port 4747.

secpack 4747/udp 
secpack-trap 4749/udp

=> Add these lines and restart brass services.

=> Now try to discover devices.
