Dissects part of syslog message based on OID

edit

Hello,

I am working on a dissector which shall dissect part of syslog messages based on the OID so the specific syslog messages using the OID shall be dissected on my protocol whereas other syslog messages shall be dissected on the regular syslog protocol defined in packet-syslog.c. So both the protocol shall use the same UDP port but I want the higher level UDP to send the packets to my protocol when the OID matches. Is this even possible?

Any advice is highly appreciated as I am not sure how to go about achieving this.

Best Regardsd
