Private Traps
and MIB Files
Traps are used to signal status changes to the manager. Using traps helps to avoid
adding traffic.
The status changes signaled by the trap are for the:
z LEDs
z communication ports
z I/O scanning health values
z Global Data health
z NTP service
z SMTP service
The following list describes the characteristics of private traps, which means that
they can:
z send messages to the two managers whose IP addresses are configured in the
SNMP configuration (either the PL7 or the Web page)
z use the community name given to this configuration
z enable or disable each of the Transparent Factory Ethernet Private MIB groups:
Switch (1), Port502_Messaging (2), I/O_Scanning (3), Global_Data (4), Web (5),
Address_Server (6), Equipment_Profiles (7), NTP (8), and SMTP (9)
Private traps are described in the MIB ASN.1 description, which is contained in a
.mib text file.
NTP Traps 1. DST Change Trap: notifies the manager that the NTP server time has changed
either from (a) standard time to daylight saving time or (b) daylight saving time to
standard time
2. NTP Status Change Trap: sent when the NTP component status changes
(ntpStatus(1))
3. Leap Second Trap: sent when leap seconds are inserted
SMTP Traps 1. SMTP Status Change Trap: sent when SMTPStatus changes
2. SMTP Link to Server Status Change: sent when tSMTPLnkSrvStatus changes.
Trap is sent when service tries to send an email. Every 30 minutes a periodic test
checks the connection to the SMTP server.
