7.8 Supporting Utilities
Each line of output describes the lease information for one client. The output is
in a format that is used by the DHCPDBMOD utility to modify the lease database.
Note
The DHCPBDUMP , DHCPSHOWDBS , and DHCPDBSHOW commands perform read
operations on the database, while DHCPDBMOD performs write operations.
The DHCPDBDUMP , DHCPSHOWDBS , and DHCPDBSHOW commands accept a number of
different flags and arguments. Table 7–11 lists some of the more important
flags.
