Managing Router Physical Entities
Note Currently, the CISCO-ENTITY-FRU-CONTROL-MIB supports Cisco 7304 line cards. For additional
MIB constraints, see the “CISCO-ENTITY-FRU-CONTROL-MIB” section on page 3-21.
The following example shows a cefcModuleTable entry for a Cisco 7304 line card whose entPhysicalIndex
is 9.
cefcModuleEntry.entPhysicalIndex
cefcModuleEntry.9
cefcModuleAdminStatus = enabled(1)
cefcModuleOperStatus = ok(2)
cefcModuleResetReason = manual reset(5)
cefcModuleStatusLastChangeTime = 7714
Generating SNMP Traps
This section provides information about the SNMP traps generated in response to events and conditions
on the router, and describes how to identify which hosts are to receive traps.

Identifying Hosts to Receive Traps
You can use the CLI or SNMP to identify hosts to receive SNMP notifications and to specify the types
of notifications they are to receive (traps or informs). For CLI instructions, see the “Enabling
Notifications” section on page 4-2. To use SNMP to configure this information, use the following MIB
objects:
Use SNMP-NOTIFICATION-MIB objects, including the following, to select target hosts and specify the
types of notifications to generate for those hosts:
• snmpNotifyTable—Contains objects to select hosts and notification types:
– snmpNotifyTag is an arbitrary octet string (a tag value) used to identify the hosts to receive
SNMP notifications. Information about target hosts is defined in the snmpTargetAddrTable
(SNMP-TARGET-MIB), and each host has one or more tag values associated with it. If a host
in snmpTargetAddrTable has a tag value that matches this snmpNotifyTag value, the host is
selected to receive the types of notifications specified by snmpNotifyType.
– snmpNotifyType is the type of SNMP notification to send: trap(1) or inform(2).
• snmpNotifyFilterProfileTable and snmpNotifyFilterTable—Use objects in these tables to create
notification filters to limit the types of notifications sent to target hosts.
Use SNMP-TARGET-MIB objects to configure information about the hosts to receive notifications:
• snmpTargetAddrTable—Transport addresses of hosts to receive SNMP notifications. Each entry
provides information about a host address, including a list of tag values:
– snmpTargetAddrTagList—A set of tag values associated with the host address. If a host’s tag
value matches snmpNotifyTag, the host is selected to receive the types of notifications defined
by snmpNotifyType.
