CISCO-SNMP-TARGET-EXT-MIB
AI MIB Summary
The CISCO-SNMP-TARGET-EXT-MIB extends SNMP target configuration on Cisco devices to support IPv6 link-local and multicast notifications by specifying the egress interface and VRF context, while also providing metrics to identify the source IP of unauthenticated SNMP messages.
This MIB is an extension of the SNMP-TARGET-MIB specified in RFC3413.
This MIB module contains Cisco-defined extension to the snmpTargetAddrTable to represent information required for IPv6 Address.
When Target has Link local or Multicast IPv6 address, the information of the interface on which the notification has to be sent is required. This additional information is provided by this extension MIB.
This module also contains definition for set of new variable to hold the address of the host that had sent an unauthentic SNMP message to agent.
Glossary of the terms used in this MIB:
VRF - Virtual Routing and Forwarding. An IP technology that allows multiple instances of routing table to exist in a system and work simultaneously. A VRF consists of an IP routing table, a forwarding table, a set of interfaces that use the forwarding table, and a set of rules and routing protocol parameters that control the information that is included into the routing table.

ciscoSnmpTargetExtMIBThis MIB is an extension of the SNMP-TARGET-MIB
specified in RFC3413.
This MIB module contains Cisco-defined extension
to the snmpTargetAddrTable to represent information
required for IPv6 Address.
When Target has Link local or Multicast IPv6 address,
the information of the interface on which the
notification has to be sent is required. This
additional information is provided by this extension
MIB.
This module also contains definition for set of new
variable to hold the address of the host that had
sent an unauthentic SNMP message to agent.

allows multiple instances of routing table to exist
in a system and work simultaneously. A VRF consists of
an IP routing table, a forwarding table, a set of
interfaces that use the forwarding table, and a set of

cExtSnmpTargetAuthInetTypeThis contains the type of address
cExtSnmpTargetAuthInetAddr holds when a host sends an
unauthentic SNMP message.ro InetAddressType (INET-ADDRESS-MIB) .1.3.6.1.4.1.9.9.412.1.1.1 |
cExtSnmpTargetAuthInetAddrThis contains the address of the host from which
snmp-agent has received a SNMP message that is not
authentic.ro InetAddress (INET-ADDRESS-MIB) .1.3.6.1.4.1.9.9.412.1.1.2 |
cExtSnmpTargetAddrTableThe cExtSnmpTargetAddrTable extends
the SNMP-TARGET-MIB's snmpTargetAddrTable for providing
info on the type of interface for Link Local or Multicast
IPv6 Target Address. SEQUENCE OF CExtSnmpTargetAddrEntry .1.3.6.1.4.1.9.9.412.1.2 |
cExtSnmpTargetAddrEntryA cExtSnmpTargetAddrTable entry extends
snmpTargetAddrTable to provide a new variable
to hold the value of interface type.
A target which has a link local or a multicast
address the variable of this table is valid.
Entries are removed when the corresponding entry in the
snmpTargetAddrTable is removed. CExtSnmpTargetAddrEntry .1.3.6.1.4.1.9.9.412.1.2.1 |
cExtSnmpTargetAddrIntIfIndexHolds valid ifIndex value of the interface through
which the notifications for the target with
Multicast/Link local address specified in the
snmpTargetAddrTAddress, is sent.
If snmpTargetAddrTAddress doesn't hold a Linklocal or
a Multicast target address then the value of this
object will be zero.
For the entries with snmpTargetAddrTAddress having
Link Local or Multicast address the
snmpTargetAddrStatus cannot be set to valid unless the
value for this object holds a valid ifIndex value.rw InterfaceIndexOrZero (IF-MIB) .1.3.6.1.4.1.9.9.412.1.2.1.1 |
cExtSnmpTargetVrfTableThe cExtSnmpTargetVrfTable extends the snmpTargetAddrTable
of the SNMP-TARGET-MIB for providing:
- VRF reachability criterion for the SNMP target
- VRF filtering criterion for the SNMP target
This table is indexed by the target entity
snmpTargetAddrName and the associated VRF name
cExtSnmpTargetVrfName. Each entry of this table forms a
tuple of target and VRF name for which all the VRF related
configuration parameters can be specified by corresponding
instances of the columnar objects.
The reachability of the SNMP target is qualified by the
routing context by way of associating VRF Name(s) with it.
Restricting only those SNMP notifications that are generated
within the context of a VRF to a specific SNMP target is
VRF based filtering of notifications.
A row in this table cannot be created prior to the creation
of row it extends. SEQUENCE OF CExtSnmpTargetVrfEntry .1.3.6.1.4.1.9.9.412.1.3 |
cExtSnmpTargetVrfEntryAn entry (conceptual row) in the cExtSnmpTargetVrfTable.
When an entry in the snmpTargetAddrTable is deleted the
corresponding entries in this table are also deleted.
A row needs to exist in the cExtSnmpTargetVrfTable for
each VRF for which SNMP notifications are to be sent to
a particular target address, so that when the same
target address is the destination for multiple VRFs,
then multiple rows in this table will reference the same
target address. However, only one of such multiple rows
can be used for routing the SNMP notifications to that
target address, i.e., only one of them can have an
instance of cExtSnmpTargetVrfRoute with the value 'true'.
Thus, any management operation which sets an instance of
cExtSnmpTargetVrfRoute to 'true' must also have the
effect of setting any other instance of
cExtSnmpTargetVrfRoute for the same target address to
'false'. CExtSnmpTargetVrfEntry .1.3.6.1.4.1.9.9.412.1.3.1 |
cExtSnmpTargetVrfNameThis object identifies a human readable string representing
the name of the VRF. SnmpAdminString .1.3.6.1.4.1.9.9.412.1.3.1.1 |
cExtSnmpTargetVrfRouteThis object specifies whether this VRF (identified by the
corresponding instance identifier of cExtSnmpTargetVrfName)
should be used for routing the SNMP notifications
sent to this target address specified in the value of
the corresponding instance of snmpTargetAddrTAddress.
The value 'true' indicates that this VRF should be used.
The value 'false' indicates that this VRF should not be
used.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.412.1.3.1.2 |
cExtSnmpTargetVrfFilterThis object specifies whether SNMP notifications generated
in this VRF (identified by the corresponding instance
identifier of cExtSnmpTargetVrfName) context should be sent
to this target address specified in the value of the
corresponding instance of snmpTargetAddrTAddress.
By default, the notifications generated in any of the VRFs
are allowed to be sent to the configured targets. Setting
the value of this object to 'true' defines 'inclusive'
filtering policy to allow notifications of a specific VRF
while excluding notifications of all other VRFs.
The value 'true' indicates that the notifications of this
VRF should be sent.
The value 'false' indicates that the notifications of this
VRF should not be sent.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.412.1.3.1.3 |
cExtSnmpTargetVrfStorageThe storage type for this conceptual row.
When the value of an instance of this object is 'permanent',
the value of the corresponding instance of all the other
objects of this table except cExtSnmpTargetVrfStatus are
read-writable. The 'permanent' rows can not be deleted by
setting value of the corresponding instance of
cExtSnmpTargetVrfStatus to 'destroy'.rw StorageType (SNMPv2-TC) .1.3.6.1.4.1.9.9.412.1.3.1.4 |
cExtSnmpTargetVrfStatusThe status of this conceptual row.
There are no specific restrictions for setting the value
of this object to 'active'. Once the value of this object
is set to 'active', the value of the corresponding instance
of all other objects of this table can still be modified.rw RowStatus (SNMPv2-TC) .1.3.6.1.4.1.9.9.412.1.3.1.5 |
cExtSnmpNotifGblTrapSrcIfIndexThis object specifies the ifIdex value of the source
interface to be used for sending TRAP notifications.
The value of this object should be a valid 'ifIndex' value.
This is a global configuration applied for all TRAP
notifications sent by this agent to all the targets. If the
source interface is configured for a specific target using
the value of corresponding instance of
'cExtSnmpTargetAddrIntIfIndex', then that value takes
precedence and will be used for sending the notification.
The value of this object being 'zero' implies that there is
no source interface configuration for the TRAP
notifications at a global level.rw InterfaceIndexOrZero (IF-MIB) .1.3.6.1.4.1.9.9.412.1.4 |
cExtSnmpNotifGblInformSrcIfIndexThis object specifies the ifIdex value of the source
interface to be used for sending INFORM notifications.
The value of this object should be a valid 'ifIndex' value.
This is a global configuration applied for all INFORM
notifications sent by this agent to all the targets. If the
source interface is configured for a specific target using
the value of corresponding instance of
'cExtSnmpTargetAddrIntIfIndex', then that value takes
precedence and will be used for sending the notification.
The value of this object being 'zero' implies that there is
no source interface configuration for the INFORM
notifications at a global level.rw InterfaceIndexOrZero (IF-MIB) .1.3.6.1.4.1.9.9.412.1.5 |
