Command mode: Global Mode
Usage Guide:
This command is used to configure a DHCP address pool under Global
Mode and enter the DHCP address configuration mode.
Example: Defining an address pool named “1”.
Switch(Config)#ip dhcp pool 1
Switch(dhcp-1-config)#
10.2.2.12 loghost dhcp
Command: loghost dhcp
no loghost dhcp
Function: Enables DHCP logging and specify the IP address and port number for the
DHCP logging host; the “no loghost dhcp” command disables the DHCP logging
function.
Parameters: is the DHCP log host IP address in decimal format. <port> is
the port number, valid values range from 0 -65535.
Default:
DHCP logging is disabled by default.
Command mode: Global Mode
Usage Guide: The user can check information about DHCP address assignment from
the log host when this command is configured. Any host running logtest.exe provided by
Edge-Core can be a DHCP log host.
Example: Enabling the DHCP logging, the log host is 192.168.1.101, port 45.
Switch(Config)#loghost dhcp 192.168.1.101 45
10.2.2.13 lease
Command: lease (infinite | <0-365>days (<0-23>hours (<0-59>minutes|)|))
no lease
Function: Sets the lease time for addresses in the address pool; the “no lease”
command restores the default setting.
Parameters: is number of days from 0 to 365; is number of hours from
0 to 23; 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 ES4624-SFP/ES4626-SFP switch is 1 day.
Example: Setting the lease of DHCP pool “1” to 3 days 12 hours and 30 minutes.
