DESCRIPTION

    A mixin class for vlan related infos from the CISCO-VTP-MIB for
    802.1Q-trunks and CISCO-VLAN-MEMBERSHIP-MIB for access ports. The
    mixin-module provides methods for mapping between vlan-ids and
    vlan-names und relations between interfaces and vlan-ids, tagged or
    untagged on these ports.

MIXIN METHODS

 OBJ->map_vlan_id2name()

    Returns a hash reference with vlan-ids as keys and the corresponding
    vlan-names as values:

      {
        vlan_id => vlan_name,
        vlan_id => vlan_name,
        ... ,
      }

 OBJ->map_vlan_id2if_idx()

    Returns a hash reference with the vlan-ids as keys and tagged and
    untagged if_idx as values:

      {
        vlan_id => {
          tagged   => [if_idx, ..., ],
          untagged => [if_idx, ..., ],
        },
    
        ... ,
      }
        

 OBJ->map_if_idx2vlan_id()

    Returns a hash reference with the interfaces as keys and tagged and
    untagged vlan-ids as values:

      {
        if_idx => {
          tagged   => [vlan_id, ..., ],
          untagged => [vlan_id, ..., ],
        },
    
        ... ,
      }
        

INITIALIZATION

 OBJ->_init($reload)

    Fetch basic Vlan related SNMP values from the host. Don't call this
    method direct!

PRIVATE METHODS

    Only for developers or maintainers.

 _fetch_vtp_vlan_tbl_entries($session)

    Fetch selected rows from vtpVlanTable during object initialization.

 _vtp_vlan_tbl_entries_cb($session)

    The callback for _fetch_vtp_vlan_tbl_entries.

 _fetch_vtp_vlan_trunk_port_tbl_entries($session)

    Fetch selected rows from vlanTrunkPortTable during object
    initialization.

 _vtp_vlan_trunk_port_tbl_entries_cb($session)

    The callback for _fetch_vtp_vlan_trunk_port_tbl_entries.

 _fetch_vm_membership_tbl_entries($session)

    Fetch selected rows from vmMembershipTable during object
    initialization. The table maybe empty if there is no switch port in
    access mode.

 _vm_membership_tbl_entries_cb($session)

    The callback for _fetch_vm_membership_tbl_entries.
