unconfigure vlan dhcp-options
unconfigure vlan <vlan-name> dhcp-options {<start-addr>}
Description
Clears the DHCP options for the specified address range in a VLAN.
Syntax Description
Default
N/A
Usage Guidelines
Use this command to unconfigure, or clear, the DHCP options for the specified address range in a
VLAN.
A VLAN can have multiple DHCP address ranges; therefore, the
start-addr
parameter identifies the
DHCP address range that requires clearing of DHCP options.
The DHCP address range is identified as the range whose starting IP address is the same as
start-addr
. If
start-addr
is not provided, then the DHCP options for the primary address range will
be cleared.
To configure DHCP options for the specified address range in a VLAN, use the following command:
configure vlan dhcp-options
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. Assume that for the DHCP Address range 40.0.0.5 to 40.0.0.40 the DHCP gateway is
configured as 40.0.0.90. Similarly, assume that for the DHCP address range 50.0.0.5 to 50.0.0.40 the
DHCP gateway is configured as 50.0.0.90.
To unconfigure the DHCP options for the primary subnet, use the following command:
unconfigure vlan test dhcp-options
To unconfigure the DHCP options for the DHCP address range starting from 50.0.0.5, use the following
command:
unconfigure vlan test dhcp-options 50.0.0.5
vlan-name
Specifies the name of the VLAN to be unconfigured.
dhcp-options
Specifies that DHCP options are to be unconfigured.
start-addr
(Optional) Specifies the starting address of the range for which DHCP options are to be
unconfigured.
