Configuring Other SNMP Trap Events
There are a number of SNMP events that require configuration on the switch before they can be used in
EPICenter alarm definitions. If the configuration is not done on the switch, no trap events are generated,
and no EPICenter alarms for those events can occur. The Ping and OSPF traps fall into this category.
To configure the switch to send one of these traps, you must use a tool that allows you to set the value
of the appropriate SNMP variable. Tools such as SNMPc can be used to perform this function. The
following information assumes that you have a thorough understanding of SNMP and an appropriate
SNMP utility.
Refer to the appropriate MIBs for details of the variable settings:
• Ping MIB: pingmib.mib (RFC 2925)
•
OSPF v2 MIB: RFC 1850 or RFC 1850t
