When the value of ztmxSwitchToBackupNow is set to a 1. If a backup process
exists, the Trap Multiplexer’s backup process takes over, refreshing all values in
the Trap Multiplexer’s MIB before handling SNMP manager requests or processing
incoming traps. After takeover is complete, the Trap Multiplexer sets the value of
ztmxSwitchToBackupNow to 0. Use the ztmxProcKeepAliveTimer startup
parameter if you want to keep monitoring a TCP/IP process that has gone down
until it comes back up.
ztmxProcTcpIpProcess maintains the list of TCP/IP processes being monitored by the
Trap Multiplexer in the following format:
$tcpname1:ipaddr1, ipaddr2 $tcpname2
For more information about using the -t parameter and PARAMs, see Using the -t and
PARAM Startup Parameters on page 12-10.
EMS Messages
This subsection describes the EMS events generated by the Trap Multiplexer
(subsystem abbreviation ZTMX).
Event Summary
The Trap Multiplexer generates events that fall into two categories:
•
Trap events. These events describe each trap received.
•
Process events. These events highlight Trap Multiplexer process changes.
Trap Events
The trap events are listed in Table 12-4. Each SNMP trap type has a corresponding
event.
Each header variable of a trap PDU is mapped to an EMS token, as Figure 12-2
illustrates.
