SNMP::Info::MAU(3) User Contributed Perl Documentation SNMP::Info::MAU(3) NAME SNMP::Info::MAU - SNMP Interface to Medium Attachment Unit (MAU) MIB (RFC 2668) via SNMP AUTHOR Max Baker SYNOPSIS my $mau = new SNMP::Info ( AutoSpecify => 1, Debug => 1, DestHost => 'hpswitch', Community => 'public', Version => 2 ); my $class = $mau->class(); print " Using device sub class : $class\n"; DESCRIPTION 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. MAU = Medium Attachment 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(...); Inherited Classes None. Required MIBs MAU-MIB IANA-MAU-MIB GLOBALS These are methods that return scalar value from SNMP None TABLE METHODS These are methods that return tables of information in the form of a reference to a hash. $mau->mau_i_duplex() Parses mau_index and mau_link to return the duplex information for interfaces. $mau->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->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->mau_i_speed_admin() Returns admin speed setting for all the interfaces. MAU Interface Table Methods $mau->mau_index() - Returns a list of interfaces and their index in the MAU IF Table. ("ifMauIfIndex") $mau->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->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->mau_up() - Returns the current link condition (C<ifMauMediaAvailable>) $mau->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->mau_type_admin() ("ifMauDefaultType") $mau->mau_auto() - Indicates whether or not auto-negotiation is supported. ("ifMauAutoNegSupported") $mau->mau_autostat() - Returns status of auto-negotiation mode for ports. ("ifMauAutoNegAdminStatus") $mau->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->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") SET METHODS These are methods that provide SNMP set functionality for overridden methods or provide a simpler interface to complex set operations. See "SETTING DATA VIA SNMP" in SNMP::Info for general information on set operations. $mau->mau_set_i_speed_admin(speed, ifIndex) Sets port speed, must be supplied with speed and port "ifIndex". Note that this method has some limitations since there is no way to reliably set the port speed independently of the port duplex setting on certain devices, notably the Cisco Cat4k series. Speed choices are '10', '100', '1000', 'auto'. $mau->mau_set_i_duplex_admin(duplex, ifIndex) Sets port duplex, must be supplied with duplex and port "ifIndex". Note that this method has some limitations since there is no way to reliably set the port duplex independently of the port speed setting on certain devices, notably the Cisco Cat4k series. Duplex choices are 'auto', 'half', 'full'. $mau->mau_set_i_speed_duplex_admin(speed, duplex, ifIndex) Sets port speed and duplex settings, must be supplied with speed, duplex and port "ifIndex". Accepts the following values for speed and duplex: Speed/Duplex ------------ auto/auto (this is a special case) 10/half 10/full 100/half 100/full 1000/half 1000/full Utility Functions munge_int2bin() - Unpacks an integer into a 32bit bit string. $mau->_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. $mau->_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. perl v5.32.1 2021-02-28 SNMP::Info::MAU(3)
