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.

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
    }

    ... ,
  }

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

Only for developers or maintainers.

Get some MIB values from the ifTable needed by all other modules.

The callback for _fetch_if_table_entries

Get some MIB values from the ifXTable needed by all other modules.

The callback for _fetch_if_x_table_entries

Net::SNMP::Mixin::Dot1dBase for a mapping between ifIndexes and dot1dBasePorts.
