DHCP Commands
lease
This command configures the duration of the lease for an IP address that a DHCP server assigns to
a DHCP client. The lease time set is the system default value which overrides the non‐specified
default value (one day).
If the client requests a lease period exceeding the period configured on the server, the lease
interval offered by the server will equal that of the value configured by this command. If the client
does not request a particular lease period ‐ typical client behavior ‐ it is granted the configured
default value. Manual bindings are not held accountable to this lease period.
Depending on the client configuration inheritance, the command should be used from the proper
mode. If it is specified from multiple modes, an override mechanism chooses the innermost config
value, with client‐class as innermost, then pool as most general.
