Table entries are created with an ADD command, and removed with a
DELETE command. The ADD command specifies the most important
parameters of the entry. Additional parameters are usually specified with the
SET command, which is also used to change configured parameters.
The LIST command displays table entries. For example, LIST
MODEM_GROUPS displays all defined modem groups.
The SHOW command displays detailed information about a specific table
entry or a set of scalars (non-table items). For example, SHOW
MODEM_GROUP USR displays information on the USR modem group.
The order of items in a table is
usually
not relevant, nor is it inherent in the
type of entity. Sometimes the order is relevant, and you must specify a
preference
value in the ADD command, indicating where this item belongs in
the table. For example,
add dns server <server_name> preference 1
assigns a
priority of 1 to this DNS server. The DNS server with the highest preference
number will be used first. Login hosts also require a preference number.
