Zone Information
Protocol
AppleTalk uses the Zone Information Protocol (ZIP) to maintain a mapping
between networks and zone names. This network-to-zone mapping is
used to facilitate the name-lookup process performed by the Name
Binding Protocol. Your system allows you to view a variety of ZIP statistics,
including:
■
inErrors — Number of ZIP packets that have been received and
rejected for any error
■
inExReplies — Number of ZIP extended replies that have been
received
■
inGniReplies
— Number of ZIP GetNetInfo reply packets that have
been received

■
inObsoletes — Number of ZIP Takedown or ZIP Bringup packets that

■
inQueries — Number of ZIP queries that have been received
■

between this system’s zone information and another entity’s zone
information
■

GetNetInfo reply with the zone invalid bit set because the
corresponding GetNetInfo request had an invalid zone name
■
