In BRIDGE-MIB it is specified that we receive two traps
1.newRoot
2.topologyChange
As per MIB we do not receive any objects
newRoot NOTIFICATION-TYPE
-- OBJECTS { }
STATUS current
DESCRIPTION
"The newRoot trap indicates that the sending agent has
become the new root of the Spanning Tree; the trap is
sent by a bridge soon after its election as the new
root, e.g., upon expiration of the Topology Change Timer,
immediately subsequent to its election. Implementation
of this trap is optional."
::= { dot1dNotifications 1 }
topologyChange NOTIFICATION-TYPE
-- OBJECTS { }
STATUS current
DESCRIPTION
"A topologyChange trap is sent by a bridge when any of
its configured ports transitions from the Learning state
to the Forwarding state, or from the Forwarding state to
the Blocking state. The trap is not sent if a newRoot
trap is sent for the same transition. Implementation of
this trap is optional."
::= { dot1dNotifications 2 }But when I receive traps for topology change I receive two more OID's with it .. I am unable to understand how did IOS send objects with the trap when it is not mentioned in the MIB ?
Example of trpa is as below:
