This document is based on the Proposed Standard MAU MIB, RFC 2668
[RFC2668], edited by John Flick of Hewlett-Packard and Andrew Smith,
then of Extreme Networks, and produced by the Ethernet Interfaces and
Hub MIB Working Group. It extends that document by providing support
for 10 Gb/s MAUs as defined in [IEEE802.3ae].
RFC 2668, in turn, was based on the Proposed Standard MAU MIB, RFC
2239 [RFC2239], edited by Kathryn de Graaf, then of 3Com, and Dan
Romascanu, then of Madge Networks, and produced by the Ethernet
Interfaces and Hub MIB Working Group. It extended that document by
providing support for 1000 Mb/sec MAUs as defined in [IEEE802.3].
RFC 2239, in turn, was based on the Proposed Standard MAU MIB, RFC
1515 [RFC1515], edited by Donna McMaster, then of SynOptics
Communications, Keith McCloghrie, then of Hughes LAN Systems, and Sam
Roberts, then of Farallon Computing, and produced by the Hub MIB
Working Group. It extends that document by providing support for 100
Mb/sec MAUs, full duplex MAUs, and auto-negotiation, as defined in
[IEEE802.3].

9. Security Considerations
There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write. Setting these objects can
have a serious effect on the operation of the network, including:
o enabling or disabling a MAU
o changing a MAU’s default type
o enabling, disabling or restarting autonegotiation
o modifying the capabilities that a MAU advertizes during
autonegotiation.
Such objects may be considered sensitive or vulnerable in some
network environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. In some environments it may
be undesirable to allow unauthorized parties to access statistics or
status information about individual links in a network. It is thus
important to control even GET and/or NOTIFY access to these objects
and possibly to even encrypt the values of these objects when sending
them over the network via SNMP.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
even then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects
in this MIB module.
It is recommended that the implementors consider the security
features as provided by the SNMPv3 framework (see [RFC3410], section
8), including full support for the SNMPv3 cryptographic mechanisms
(for authentication and privacy).
Furthermore, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
