DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide
207
14-4
default-router
This command is used to define the default gateway of the DHCP client in the DHPC address pool configuration mode.
The no form of this command can be used to delete the definition of the default gateway.
default-router
ip-address
[
ip-address2
[
ip-address3
]]
no default-router
Parameters
14-5
dns-server
This command is used to define the DNS server of the DHCP client in the DHPC address pool configuration mode. The
no form of this command can be used to delete the definition of the DNS server.
dns-server
ip-address
[
ip-address2
[
ip-address3
]]
Usage Guideline
The DHCP server uses the ping session to detect the address conflict, while the
DHCP client uses the address resolution protocol (ARP) to detect the address
conflict. The
clear ip dhcp conflict
command can be used to delete the history
conflict record.
Note the following behavior for the
clear ip dhcp conflict
command:
If you do not specify the VRF name option and an IP address is specified, it is
assumed that the IP address is an address in the global address space and
will look among all the nonvirtual VRF DHCP pools for the specified conflict.
If you do not specify the VRF name option and the * option is specified, it is
assumed that all automatic or on-demand conflicts in all VRF and non-VRF
pools are to be deleted.
If you specify both the VRF name option and the * option, all automatic or on-
demand conflicts in the specified pool only will be cleared.
If you specify the VRF name option and an IP address, the specified conflict will
be deleted from the specified pool.
Example
This example shows how to clear all address conflict records.
DXS-3600-32S#clear ip dhcp conflict *
DXS-3600-32S#
ip-address
Specifies to define the IP address of the equipment. It is required to configure one IP
address at least.
ip-address2 ip-address3
(Optional) Up to 3 gateways can be configured.
Default
No gateway is defined by default.
Command Mode
DHCP Address Pool Configuration Mode.
Command Default Level
Level: 8
Usage Guideline
In general, the DHCP client should get the information of the default gateway from
the DHCP server. The DHCP server should specify one gateway address for the
client at least, and this address should be of the same network segment as the
address assigned to the client.
Example
This example shows how to define 192.168.12.1 as the default gateway.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#ip dhcp pool pool1
DXS-3600-32S(dhcp-config)#default-router 192.168.12.1
DXS-3600-32S(dhcp-config)#
