10.2.2.13 lease
Command: lease (infinite | <0-365> (<0-23> (<0-59>|)|))
no lease
Function:
Sets the lease time for addresses in the address pool; the “
no lease
”
command restores the default setting.
Parameters:
<days>
is number of days from 0 to 365;
<hours
is number of hours from 0
to 23;
<minutes>
is number of minutes from 0 to 59;
infinite
means perpetual use.
Default:
The default lease duration is 1 day.
Command Mode:
DHCP Address Pool Mode
Usage Guide:
DHCP is the protocol to assign network addresses dynamically instead of
permanently, hence the introduction of ease duration. Lease settings should be decided
based on network conditions: too long lease duration offsets the flexibility of DHCP, while
too short duration results in increased network traffic and overhead. The default lease
duration of ES3628EA switch is 1 day.
Example:
Setting the lease of DHCP pool “1” to 3 days 12 hours and 30 minutes.
Switch(dhcp-1-config)#lease 3 12 30
