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 ES4700 series 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
