A cospfIfConfigError  trap  signifies  that  a
packet  with mismatched parameter MTU has been 
received on a non-virtual interface  from  a  
router.

A cospfShamLinkConfigError signifies that a packet 
has been received on a sham link from a router whose
configuration parameters conflict with this router's
configuration parameters.

A cospfShamLinkAuthFailure trap signifies that a 
packet has been received on a sham link from a router
whose authentication key or authentication type conflicts
with this router's authentication key and authentication 
type.

A cospfShamLinkRxBadPacket trap signifies that an OSPF
packet has been received on a sham link that cannot be 
parsed.

A cospfShamLinkTxRetransmit trap signifies that an 
OSPF packet has been retransmitted on a sham link. All 
packets that may be retransmitted are associated with an 
LSDB entry. The LS type, LS ID, and Router ID are used 
identify the LSDB entry.

A ospfShamLinkStateChange trap signifies that 
there has been a change in the state of a Sham
Link OSPF interface. This trap should  be  generated
when  the interface state regresses from  Point-to-Point
to Down or progresses  to  Down to Point-to-Point.

A cospfVirtIfConfigError  trap  signifies  that  a
packet  with mismatched parameter MTU has been received
on a virtual interface  from  a router.

A cospfTxRetransmit  trap  signifies  than  an
OSPF  packet, which has been associated with 
an Opaque LSA LSDB Entry, has  been retransmitted 
on a non-virtual interface.

A cospfVirtTxRetransmit  trap  signifies  than  an
OSPF  packet, which has been associated with 
an Opaque LSA LSDB Entry, has  been retransmitted 
on a non-virtual interface.

A cospfOriginateLsa trap signifies that a  new
Opaque LSA  has  been originated by this router.
This trap should not be invoked for simple refreshes
of  LSAs  (which happesn every 30 minutes), but
instead will only be invoked  when  an  LSA  is
(re)originated due to a topology change.  Additionally, 
this trap does not include LSAs  that
are  being  flushed  because  they have reached
MaxAge.

A cospfMaxAgeLsa trap signifies  that  one  of
the Opaque LSAs in the router's link-state database 
has aged to MaxAge.

A cospfNssaTranslatorStatusChange trap indicates that there
has been a change in the router's ability to translate OSPF
type-7 LSAs into OSPF type-5 LSAs. This trap should be
generated when the Translator Status transitions from or to
any defined status on a per area basis.

A ospfShamLinkStateChange trap signifies that 
there has been a change in the state of a Sham
Link OSPF interface. This trap should  be  generated
when  the interface state regresses from  Point-to-Point
to Down or progresses to Down to Point-to-Point. This
trap has been deprecated by cospfShamLinksStateChange.

A cospfShamLinkNbrStateChange trap signifies that
there has been a change in the state of a sham link
OSPF neighbor. This trap should be generated when 
the neighbor state regresses (e.g., goes from 
Attempt or Full to 1-Way or Down) or progresses to
a terminal state (e.g., Full).
