SYNOPSIS

13        my $mau = new SNMP::Info (
14                                    AutoSpecify => 1,
15                                    Debug       => 1,

DESCRIPTION

25       SNMP::Info::MAU is a subclass of SNMP::Info that supplies access to the
26       MAU-MIB (RFC 2668). This MIB is sometimes implemented on Layer 2
27       network devices like HP Switches.  MAU = Media Access Unit.
28
29       The MAU table contains link and duplex info for the port itself and the
30       device connected to that port.
31
32       Normally you use or create a subclass of SNMP::Info that inherits this
33       one.  Do not use directly.
34
35       For debugging purposes call the class directly as you would SNMP::Info
36
37        my $mau = new SNMP::Info::MAU(...);
38
39   Inherited Classes
40       None.

42   Required MIBs

GLOBALS

46       These are methods that return scalar value from SNMP
47
48       None

TABLE METHODS

51       These are methods that return tables of information in the form of a
52       reference to a hash.
53
54       $mau->mau_i_duplex()
55           Parses mau_index and mau_link to return the duplex information for
56           interfaces.
57
58       $mau->mau_i_duplex_admin()
59           Parses "mac_index","mau_autostat","mau_type_admin" in order to find
60           the admin duplex setting for all the interfaces.
61
62           Returns either (auto,full,half).
63
64       $mau->mau_i_duplex_admin_old()
65           Called by mau_i_duplex_admin() if "mau_type_admin" is empty.
66           Parses "mau_index","mau_autostat","mau_autosent" in order to find
67           the admin duplex setting for all the interfaces.
68
69           Returns either (auto,none,full,half).
70
71       $mau->mau_i_speed_admin()
72           Returns admin speed setting for all the interfaces.
73
74   MAU INTERFACE TABLE METHODS
75       $mau->mau_index() -  Returns a list of interfaces and their index in
76       the MAU IF Table.
77           ("ifMauIfIndex")
78
79       $mau->mau_link() - Returns the type of Media Access used.
80               This is essentially the type of link in use.
81               eg. dot3MauType100BaseTXFD - 100BaseT at Full Duplex
82
83           ("ifMauType")
84
85       $mau->mau_status() - Returns the admin link condition as
86               1 - other
87               2 - unknown
88               3 - operational
89               4 - standby
90               5 - shutdown
91               6 - reset
92
93           Use 5 and !5 to see if the link is up or down on the admin side.
94
95           ("ifMauStatus")
96
97       $mau->mau_up() -  Returns the current link condition
98            (C<ifMauMediaAvailable>)
99
100       $mau->mau_type() - Returns a 32bit string reporting the capabilities of
101       the port from a MAU POV.
102             Directly from F<MAU-MIB> :
103                     Bit   Capability
104                       0      other or unknown
