Current SNMP agent settings:
Enabled  : 1
UDP port : 162

Communities :
xxxx

Notification targets :
10.138.4.67@162/xxxx

but on my OME server

When I run the SNMP test in Troubleshooting tool, i get:

The SNMP read request has failed for Get Community name - xxxx

Under the machine details - Software Agent Information

Server Administrator is flagged as yellow with Agent Version showing as N/A

Any ideas?

Regards,
