OK.  I can live with that.  I just wanted to make sure _I_ wasn't doing
anything wrong.

Actually... In the course of  hunting down MIBs for stuff I've tripped over,
I have found the following from Cisco that fall outside of the normal
'1.3.6...' branch:

IEEE8021-PAE-MIB     -    1.0.8802.1.1.1                also known as:
iso.std.iso8802.ieee802dot1.ieee802dot1mibs.ieee8021paeMIB
IEEE8023-LAG-MIB     -    1.2.840.10006.300.43    also known as:
iso.member-body.us.ieee802dot3.snmpmibs.lagMIB
