Security Commands
unconfigure vlan dhcp-address-range
unconfigure vlan <vlan-name> dhcp-address-range {<start-addr>}
Description
Clears the specified DHCP address range in the a VLAN.
Syntax Description
Default
N/A
Usage Guidelines
Use this command to unconfigure, or clear, the specified DHCP address in a VLAN.
A VLAN can have multiple DHCP address ranges; therefore, the
start-addr
parameter identifies the
DHCP address range for which the clearing needs to be done.
The DHCP address range is identified as the one whose starting IP address is the same as
start-addr
.
If
start-addr
is not provided, then the primary DHCP address range will be unconfigured.
Examples
Consider a VLAN named test with a primary subnet 40.0.0.x/24 and a secondary subnet 50.0.0.x/24.
Assume that for the primary subnet a DHCP address range is configured ranging from 40.0.0.5 to
40.0.0.40. Similarly, for the secondary subnet the DHCP address range is configured ranging from
50.0.0.5 to 50.0.0.40.
To unconfigure the DHCP address range of the primary subnet, use the following command:
unconfigure vlan test dhcp-address-range
To unconfigure the DHCP address range with the
start-addr
as 50.0.0.5, use the following command
unconfigure vlan test dhcp-address-range 50.0.0.5
NOTE
You can configure multiple DHCP address ranges for a VLAN. The start-addr option in the command
(50.0.0.5 in this example) specifies the exact DHCP address range for which the command applies. If
the last option is not specified, the command is applied for the primary subnet.
vlan-name Specifies the name of the VLAN to be unconfigured.
dhcp-address-range Specifies that DHCP address range to be unconfigured.
start-addr (Optional) Specifies the starting address of the DHCP address range to be
unconfigured.
