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 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
