> ... copied over essentially all of the core files

I'm guessing one or more files on the new machine don't match up with
the files on the old machine & you're missing a display hint on the
new machine.

I have non-standard mib files & locations, so I can't point you to a
set of files to check.
What you'll need to do is find the file where dot1dTpFdbAddress is
defined; for me it's in BRIDGE-MIB.my:
dot1dTpFdbAddress OBJECT-TYPE
    SYNTAX      MacAddress
    MAX-ACCESS  read-only
    STATUS      current

no display hint, so find where MacAddress is defined; probably near
the top of the file:
IMPORTS MacAddress FROM SNMPv2-TC

figure out where SNMPv2-TC comes from, look in there for the
definition of MacAddress

MacAddress ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "1x:"
    STATUS       current
    DESCRIPTION
            "Represents an 802 MAC address represented in the
            `canonical' order defined by IEEE 802.1a, i.e., as if it
            were transmitted least significant bit first, even though
            802.5 (in contrast to other 802.x protocols) requires MAC
            addresses to be transmitted most significant bit first."
    SYNTAX       OCTET STRING (SIZE (6))

add the display hint if it's missing.

Regards,
Lee
