SYNOPSIS

        # Let SNMP::Info determine the correct subclass for you.
        my $c2900 = new SNMP::Info(
                               AutoSpecify => 1,
                               Debug       => 1,
                               # These arguments are passed directly to SNMP::Session
                               DestHost    => 'myswitch',
                               Community   => 'public',
                               Version     => 2
                               )
           or die "Can't connect to DestHost.\n";

        my $class = $c2900->class();
        print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

       Provides abstraction to the configuration information obtainable from a C2900 device
       through SNMP.

       For speed or debugging purposes you can call the subclass directly, but not after
       determining a more specific class using the method above.

        my $c2900 = new SNMP::Info::Layer2::C2900(...);

   Inherited Classes
       SNMP::Info::Layer2::Cisco

   Required MIBs
       CISCO-C2900-MIB
           Part of the v2 MIBs from Cisco.

   Inherited MIBs
       See "Required MIBs" in SNMP::Info::Layer2::Cisco for its MIB requirements.

GLOBALS

       These are methods that return scalar value from SNMP

   Overrides
       $c2900->vendor()
           Returns 'cisco' :)

       $c2900->cisco_comm_indexing()
           Returns 1.  Use vlan indexing.

   Globals imported from SNMP::Info::Layer2::Cisco
       See "GLOBALS" in SNMP::Info::Layer2::Cisco for details.

TABLE METHODS

       These are methods that return tables of information in the form of a reference to a hash.

   Overrides
       $c2900->interfaces()
           Returns reference to the map between IID and physical Port.

           On the 2900 devices i_name isn't reliable, so we override to just the description.

           Next all dots are changed for forward slashes so that the physical port name is the
           same as the broad-casted CDP port name.
               (Ethernet0.1 -> Ethernet0/1)

           Also, any weird characters are removed, as I saw a few pop up.

       $c2900->i_duplex()
           Returns reference to map of IIDs to current link duplex

           Crosses $c2900->c2900_p_index() with $c2900->c2900_p_duplex()

       $c2900->i_duplex_admin()
           Returns reference to hash of IIDs to admin duplex setting

           Crosses $c2900->c2900_p_index() with $c2900->c2900_p_duplex_admin()

       $c2900->i_speed_admin()
           Returns reference to hash of IIDs to admin speed setting.

   C2900-MIB Port Entry Table
       $c2900->c2900_p_index()
           Maps the Switch Port Table to the IID

           ("c2900PortIfIndex")

       $c2900->c2900_p_duplex()
           Gives Port Duplex Info

           ("c2900PortDuplexStatus")

       $c2900->c2900_p_duplex_admin()
           Gives admin setting for Duplex Info

           ("c2900PortDuplexState")

       $c2900->c2900_p_speed_admin()
           Gives Admin speed of port

           ("c2900PortAdminSpeed")

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.

       $c2900->set_i_speed_admin(speed, ifIndex)
           Sets port speed, must be supplied with speed and port "ifIndex"

           Speed choices are 'auto', '10', '100'

           Crosses $c2900->c2900_p_index() with $c2900->c2900_p_speed_admin() to utilize port
           "ifIndex".

               Example:
               my %if_map = reverse %{$c2900->interfaces()};
               $c2900->set_i_speed_admin('auto', $if_map{'FastEthernet0/1'})
                   or die "Couldn't change port speed. ",$c2900->error(1);

       $c2900->set_i_duplex_admin(duplex, ifIndex)
           Sets port duplex, must be supplied with duplex and port "ifIndex"

           Speed choices are 'auto', 'half', 'full'

           Crosses $c2900->c2900_p_index() with $c2900->c2900_p_duplex_admin() to utilize port
           "ifIndex".

               Example:
               my %if_map = reverse %{$c2900->interfaces()};
               $c2900->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'})
                   or die "Couldn't change port duplex. ",$c2900->error(1);
