SNMP Shows 4G WWAN EHWIC Card as GigE0/3!!!

[scot.a.geer]

I have a Cisco 2901 router with a 4G LTE Verizon EHWIC Cellular card. For some reason, a "GigabitEthernet0/3" interface shows up under this cellular card in our SNMP data. There are only 2 embedded GigE interfaces on this router. The output from "show diag" lists the proper interfaces, but any SNMP data pops in this extra GigE interface!

I have attached a screenshot and a text file output.

Any ideas why this extra GigE interface shows up?

UPDATE:  23 Aug 2013

Looks like this is some sort of backplane interface? See jpgs.

Hi,

we do not have a 4G card, but we are having the same issue, via snmp we are getting g0/3 which does not exist at the router.
