DESCRIPTION

A mixin class for basic interface related infos from the ifTable and ifXTable.

This mixin supports the quasi static information from both tables together in one hash, see below.

MIXIN METHODS
OBJ->get_if_entries
Returns parts ot the ifTable and ifXTable as a hash reference. The key is the common ifIndex into the ifTable and ifXtable:

      {
        INTEGER => {    # ifIndex as key

          ifName        => DisplayString,    # an ifXTable entry
          ifAlias       => DisplayString,    # an ifXTable entry

          ifDescr       => DisplayString,    # an ifTable entry
          ifType        => IANAifType,       # an ifTable entry
          ifAdminStatus => INTEGER,          # an ifTable entry
          ifOperStatus  => INTEGER,          # an ifTable entry
        }

        ... ,
      }

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