When an SNMP agent receives a request that does not contain a valid community name or the host that is sending the
message is not on the list of acceptable hosts, the agent can send an authentication trap message to one or more trap
destinations (management systems). The trap message indicates that the SNMP request failed authentication. This is a
default setting.
Question: Why does OpenManage Essentials not support entering host names with underscore in the discovery wizard?
Answer: Per RFC 952, underscores are not valid in DNS names. A
name
(net, host, gateway, or domain name) is a text
string up to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus sign (-), and period (.). Periods are only
allowed when they serve to delimit components of domain style names.
For more information see,ietf.org/rfc/rfc952.txt and zytrax.com/books/dns/apa/names.html .
Question: What is On-demand?
Answer: On-demand is an operation where a managed system is checked for status/health by OpenManage Essentials
when an SNMP trap is received. There are no settings to be changed to enable the on-demand feature. However, the IP
address of the management system must be available in the trap destination of SNMP service. An SNMP trap is
received from the managed system when there is an issue or failure of a server component. These traps can be viewed
under the alert logs.
