The rule triggers on the SNMP request id.Hmm, that's quite odd. The rule should avoid hitting that packet with the depth and offset keywords.
The rule parameters are depth:15 and offset:5 so the content clause is restricted to payload offsets 5-19. The offending match is at offset 17 so well within the rule scope.
