mib/trap authentification

[Enzymir]

Hello,

i have an unknown trap from a juniper erx router with the id: .1.3.6.1.4.1.4874.2.2.7.6
I have now the problem to find the real mib for that specific trap.
I got a lot of juniper mibs in a bundle, but how can i verify that specific trap to a specific mib?

I dont want to upload all juniper mibs, i only want to upload the mib, who has this specific trap.

I hope anybody can help me with a little faq, oder a howto with such problems in the web.

Best regards

Mathis
