SYNOPSIS

        my $c1900 = new SNMP::Info(
                                 AutoSpecify => 1,
                                 Debug       => 1,

                               )
           or die "Can't connect to DestHost.\n";

DESCRIPTION

       Provides abstraction to the configuration information obtainable from a Catalyst 1900
       device through SNMP.  See SNMP::Info for full documentation

       Note that most of these devices only talk SNMP version 1, but not all.

GLOBALS

       These are methods that return scalar value from SNMP

       $c1900->c1900_flash_status()
           Usually contains the version of the software loaded in flash.  Used by os_ver()

           "STAND-ALONE-ETHERNET-SWITCH-MIB::upgradeFlashBankStatus"

       $c1900->os()
           Returns 'catalyst'

       $c1900->os_ver()
           Returns CatOS version if obtainable.  First tries to use
           SNMP::Info::CiscoStats->os_ver() .  If that fails then it checks for the presence of
           $c1900->c1900_flash_status() and culls the version from there.

       $c1900->vendor()
           Returns 'cisco'

   Overrides
       $c1900->cisco_comm_indexing()
           Returns 1.  Use vlan indexing.

       $c1900->bulkwalk_no
           Return 1.  Bulkwalk is turned off for this class.

TABLE METHODS

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

   Overrides
       $c1900->interfaces()
           Returns reference to the map between IID and physical Port.

       $c1900->i_duplex()
           Returns reference to map of IIDs to current link duplex

       $c1900->i_duplex_admin()
           Returns reference to hash of IIDs to admin duplex setting

       $c1900->i_name()
           Crosses "ifName" with $c1900->c1900_p_name() and returns the human set port name if
           exists.

       $c1900->i_vlan()
           Returns a mapping between the interface and the VLAN / bridge group if overlap is not
           enabled.

       $c1900->i_vlan_membership()
           Returns reference to hash of arrays: key = interface, value = array of VLAN / bridge
           group IDs.

             Example:
             my $interfaces = $c1900->interfaces();
             my $vlans      = $c1900->i_vlan_membership();

             foreach my $iid (sort keys %$interfaces) {
               my $port = $interfaces->{$iid};
               my $vlan = join(',', sort(@{$vlans->{$iid}}));
               print "Port: $port VLAN: $vlan\n";
             }

       $c1900->i_vlan_membership_untagged()
           Unsupported, returns nothing.

       $c1900->bp_index()
           Returns a bp_index that contains the original bp_index entries and extra entries for
           those interfaces listed in if_index, as some C1900 devices do not return complete
           bp_indexes.

   STAND-ALONE-ETHERNET-SWITCH-MIB Switch Port Table Entries:
       $c1900->c1900_p_index()
           Maps the Switch Port Table to the IID

           "swPortIfIndex"

       $c1900->c1900_p_duplex()
           Gives Port Duplex Info

           ("swPortDuplexStatus")

       $c1900->c1900_p_duplex_admin()
           Gives admin setting for Duplex Info

           ("swPortFullDuplex")

       $c1900->c1900_p_name()
           Gives human set name for port

           ("swPortName")

       $c1900->c1900_p_up_admin()
           Gives Admin status of port enabled.

           ("swPortAdminStatus")

       $c1900->c1900_p_type()
           Gives Type of port, i.e. "general-ethernet"

           ("swPortMediaCapability")

       $c1900->c1900_p_media()
           Gives the media of the port , i.e. ""fiber-sc""

           ("swPortConnectorType")

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.

       $c1900->set_i_duplex_admin(duplex, ifIndex)
           Sets port duplex, must be supplied with duplex and port "ifIndex".  Speed choices are
           'auto', 'half', 'full'.

             Example:
             my %if_map = reverse %{$c1900->interfaces()};
             $c1900->set_i_duplex_admin('auto', $if_map{'1'})
               or die "Couldn't change port duplex. ",$c1900->error(1);
