SNMP::Info::MAU - SNMP Interface to Medium Access Unit (MAU) MIB (RFC 2668) via SNMP

SNMP::Info::MAU is a subclass of SNMP::Info that supplies access to the MAU-MIB (RFC 2668). This MIB is sometimes implemented on Layer 2 network devices like HP Switches. MAU = Media Access Unit.
The MAU table contains link and duplex info for the port itself and the device connected to that port.
Normally you use or create a subclass of SNMP::Info that inherits this one. Do not use directly.
For debugging purposes call the class directly as you would SNMP::Info
my $mau = new SNMP::Info::MAU(...);
None.
These are methods that return scalar value from SNMP
These are methods that return tables of information in the form of a reference to a hash.
mau_i_duplex()
Parses mau_index and mau_link to return the duplex information for interfaces.
mau_i_duplex_admin()
Parses mac_index,mau_autostat,mau_type_admin in
order to find the admin duplex setting for all the interfaces.
Returns either (auto,full,half).
mau_i_duplex_admin_old()
Called by mau_i_duplex_admin() if mau_type_admin is empty.
Parses mau_index,mau_autostat,mau_autosent in
order to find the admin duplex setting for all the interfaces.
Returns either (auto,none,full,half).
mau_i_speed_admin()
Returns admin speed setting for all the interfaces.
mau_index() - Returns a list of interfaces
and their index in the MAU IF Table.
(ifMauIfIndex)
mau_link() - Returns the type of Media Access used.
This is essentially the type of link in use.
eg. dot3MauType100BaseTXFD - 100BaseT at Full Duplex
(ifMauType)
mau_status() - Returns the admin link condition as
1 - other
2 - unknown
3 - operational
4 - standby
5 - shutdown
6 - reset
Use 5 and !5 to see if the link is up or down on the admin side.
(ifMauStatus)
mau_up() - Returns the current link condition
(C<ifMauMediaAvailable>)
mau_type() - Returns a 32bit string reporting the capabilities
of the port from a MAU POV.
Directly from F<MAU-MIB> :
Bit Capability
0 other or unknown
1 AUI
2 10BASE-5
3 FOIRL
4 10BASE-2
5 10BASE-T duplex mode unknown
6 10BASE-FP
7 10BASE-FB
8 10BASE-FL duplex mode unknown
9 10BROAD36
10 10BASE-T half duplex mode
11 10BASE-T full duplex mode
12 10BASE-FL half duplex mode
13 10BASE-FL full duplex mode
14 100BASE-T4
15 100BASE-TX half duplex mode
16 100BASE-TX full duplex mode
17 100BASE-FX half duplex mode
18 100BASE-FX full duplex mode
19 100BASE-T2 half duplex mode
20 100BASE-T2 full duplex mode
(ifMauTypeList)
mau_type_admin()
(ifMauDefaultType)
mau_auto() - Returns status of auto-negotiation mode for ports.
(ifMauAutoNegAdminStatus)
mau_autostat()
(ifMauAutoNegAdminStatus)
mau_autosent() - Returns a 32 bit bit-string representing the
capabilities we are broadcasting on that port
Uses the same decoder as $mau->mau_type().
(ifMauAutoNegCapAdvertised)
mau_autorec() - Returns a 32 bit bit-string representing the
capabilities of the device on the other end.
Uses the same decoder as $mau->mau_type().
(ifMauAutoNegCapReceived)
munge_int2bin() - Unpacks an integer into a 32bit bit string.
_isfullduplex(bitstring)
Boolean. Checks to see if any of the full_duplex types from mau_type()
are high. Currently bits 11,13,16,18,20.
_ishalfduplex(bitstring)
Boolean. Checks to see if any of the half_duplex types from mau_type()
are high. Currently bits 10,12,15,17,19.
