Introduction to trap
deployment
The
s have built-in Simple Network Management
Protocol (SNMP) trap receivers that operate automatically whenever the managers
are running. By default these trap receivers listen for traps on port 9000.
Information collected from the traps is used by the correlation and analysis
software inside the
s.
“Built-in IP Manager trap receiver
operation” on page 106 provides more information.
VMware recommends that you set
up an external Trap Adapter (Receiver) to filter SNMP traps before they reach
the
Domain Manager
s. Otherwise, a high volume of traps reaching the
Domain Manager
s
may adversely affect their performance. A Trap Adapter receives the traps from
the network and forwards a subset to one or more
Domain Manager
s. You may also configure the Trap Adapter to send traps
to the Adapter Platform in the
VMware Smart Assurance Service Assurance Manager
for conversion into notifications.
The Trap Adapter can receive
SNMP v1, v2c, or v3 traps. However, it forwards only v1 or v2c traps. If SNMPv3
traps are received, they are converted to a different format (v1 or v2c) before
being sent to a
Domain Manager
or to another trap receiver.
Two deployment scenarios are
possible; however, Scenario 2 is the preferred one for the production
environment.
