NAME
    Net::SNMP::Mixin::Dot1dBase - mixin class for the switch dot1d base
    values

VERSION
    Version 0.06

SYNOPSIS
    A Net::SNMP mixin class for Dot1d base info.

      use Net::SNMP;
      use Net::SNMP::Mixin;

      # class based mixin
      Net::SNMP->mixer('Net::SNMP::Mixin::Dot1dBase');

      # ...

      my $session = Net::SNMP->session( -hostname => 'foo.bar.com' );

      $session->mixer('Net::SNMP::Mixin::Dot1dBase');
      $session->init_mixins;
      snmp_dispatcher() if $session->nonblocking;
      $session->init_ok;
      die $session->errors if $session->errors;

      my $base_group = $session->get_dot1d_base_group;

      printf "BridgeAddr: %s NumPorts: %d Type: %d\n",
        $base_group->{dot1dBaseBridgeAddress},
        $base_group->{dot1dBaseNumPorts},
        $base_group->{dot1dBaseType};

      my $map = $session->map_bridge_ports2if_indexes;

      foreach my $bridge_port ( sort {$a <=> $b} keys %$map ) {
        my $if_index = $map->{$bridge_port};
        printf "bridgePort: %4d -> ifIndex: %4\n", $bridge_port, $if_index;
      }

DESCRIPTION
    A mixin class for basic switch information from the BRIDGE-MIB.

    Besides the bridge address and the number of bridge ports, it's primary
    use is the mapping between dot1dBasePorts and ifIndexes.

MIXIN METHODS
  OBJ->get_dot1d_base_group()
    Returns the dot1dBase group as a hash reference:

      {
        dot1dBaseBridgeAddress => MacAddress,
        dot1dBaseNumPorts      => INTEGER,
        dot1dBaseType          => INTEGER,
      }

  OBJ->map_bridge_ports2if_indexes()
    Returns a reference to a hash with the following entries:

      {
        # INTEGER        INTEGER
        dot1dBasePort => dot1dBasePortIfIndex,
      }

  OBJ->map_if_indexes2bridge_ports()
    Returns a reference to a hash with the following entries:

      {
        # INTEGER               INTEGER
        dot1dBasePortIfIndex => dot1dBasePort ,
      }

INITIALIZATION
  OBJ->_init($reload)
    Fetch the dot1d base related snmp values from the host. Don't call this
    method direct!

PRIVATE METHODS
    Only for developers or maintainers.

  _fetch_dot1d_base($session)
    Fetch values from the dot1dBase group once during object initialization.

  _dot1d_base_cb($session)
    The callback for _fetch_dot1d_base.

  _fetch_dot1d_base_ports($session)
    Populate the object with the dot1dBasePorts.

  _dot1d_base_ports_cb($session)
    The callback for _fetch_dot1d_base_ports.

REQUIREMENTS
    Net::SNMP, Net::SNMP::Mixin
