Is it possible to identify the trap variable number in Trap Mgr using ASL script?

I have a vendor NETOPTICS that send us traps but the var data does not tell me what port has changed link state.

The only values given in the var data is the values of 1 and 2 which are UP and Down state. A problem

arises because there are 4 ports involved. So I cannot distinguish if the port is A B C or D. Because of this

there is no way for me to setup correlation for Up/Down in fact it becomes a mess.

The only way to tell the port index is within the OID for the var.

For example

  .1.3.6.1.4.1.23022.2.5.1.2.1.1.0 --> 1 (my comment - The number 1 in the twelve location is the port A)

  .1.3.6.1.4.1.23022.2.5.1.2.2.1.0 --> 1 (my comment - The number 2 in the twelve location is the port B)

  .1.3.6.1.4.1.23022.2.5.1.2.3.1.0 --> 1 (my comment - The number 2 in the twelve location is the port C)

  .1.3.6.1.4.1.23022.2.5.1.2.4.1.0 --> 1 (my comment - The number 2 in the twelve location is the port D)

Example TRAP

========= Trap attributes  ==============

Timestamp:       13-Dec-2011 10:00:11 AM Eastern Standard Time

Agent: 10.10.10.215

Enterprise OID:  .1.3.6.1.4.1.23022

Generic Type:    6

Specific Type:   2

Processing Time: 0 Secs

Varbinds: [oid]->[varbind]

.1.3.6.1.4.1.23022.2.5.1.2.2.1.0 --> 1 (My Comment - port B down but again I cannot determine the port is B from the data and only from the OID)

I was thinking there could be a way to handle this in ASL hook script. Has anyone have any ideas? I never used the ASL script to check the var OID numbers before

of know if it is possible.
