Question on SNMP TRAP MIB definition

I have setup a localagent and masteragent where localagent sends trap to my master agent. Everything works great. Please have a look below:
MIB for trap(this is just an example)
// Trap variables definition
hbaNumber OBJECT-TYPE
SYNTAX INTEGER (0..255)
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of SCSI Host Bus Adaptor connected
to tape drive, for example 0 is first HBA on the system."
::= { devInfo 4 }
hbaChannel OBJECT-TYPE
SYNTAX INTEGER (0..255)
ACCESS read-only
STATUS mandatory
DESCRIPTION
"SCSI Channel number of SCSI Host Bus Adaptor connected
to tape drive, for example 0 is first SCSI channel of HBA."
::= { devInfo 5 }
// TRAP Definition
tapeAlertTrap280 TRAP-TYPE
ENTERPRISE tapeAlert
VARIABLES {
hbaNumber,
hbaChannel
}
DESCRIPTION
"A library operation has been attempted that is invalid at this time."
Now here, A trap is send with 2 varbinds. If i don't define the above varbind as hbaNumer or hbaChannel , does it make any difference? I know we have to give oid and value to add a varbind. But if i give some random OID(something like an OID of this trap .X.X.280) and a value of hbanumber as 3. The trap would still be genrated with some oid value and hbanumber we gave.
It is a high chance my blabber didn't make any sense.
I just want to know if we don't define the varbionds we use in traps, what could happen? Does masteragent look into varbinds and its respective oid value and does a get on localagent ?
How does masteragent react to snmptrap with defined/undefined varbinds send from localagent?
Eagerly waiting response.
Thank you..
