Use the following commands to create a pool of IP addresses. These
commands have no effect if you use the
host command. You can still set
them, however.
dhcp-option <1..254>
option_name {boolean
<0..1>| uint8 <0..255>
| uint16 <0..65535>
| uint32
<0..4294967295> | ip
ipv4 [ipv4 [ipv4]] |
fqdn fqdn [fqdn
[fqdn]] | text text |
hex hex | vivc
enterprise_id hex_s
[enterprise_id hex_s]
| vivs enterprise_id
hex_s [enterprise_id
hex_s]
Adds or edits a DHCP extended option for the specified DHCP pool.
text: String of up to 250 characters
hex: String of up to 250 hexadecimal pairs.
vivc: Vendor-Identifying Vendor Class option. A DHCP client may use this
option to unambiguously identify the vendor that manufactured the
hardware on which the client is running, the software in use, or an industry
consortium to which the vendor belongs.
enterprise_id: Number <0..4294967295>.
hex_s: String of up to 120 hexadecimal pairs.
vivs: Vendor-Identifying Vendor-Specific option. DHCP clients and servers
may use this option to exchange vendor-specific information.
no dhcp-option
<1..254>
Removes the DHCP extended option for the specified DHCP pool.
network IP/<1..32>
network ip mask
no network
Specifies the IP address and subnet mask of the specified DHCP pool. The
subnet mask can be written in w.x.y.z format or in /<1..32> format.
Note: The DHCP pool must have the same subnet as the interface
to which you plan to bind it.
The no command clears these fields.
[no] default-router ip
Specifies the default gateway DHCP clients should use. The no command
clears this field.
[no] description
description
Specifies a description for the DHCP pool for identification. The no
command removes the description.
[no] domain-name
domain_name
Specifies the domain name assigned to DHCP clients. The no command
clears this field.
[no] starting-address
ip -size <1..65535>
Sets the IP start address and maximum pool size of the specified DHCP pool.
The final pool size is limited by the subnet mask.
Note: You must specify the network number first, and the start
address must be in the same subnet.
The no command clears the IP start address and maximum pool size.
[no] first-dns-server
{ip | interface_name
{1st-dns | 2nd-dns |
3rd-dns} | ZyWALL}
Sets the first DNS server to the specified IP address, the specified interface’s
first, second, or third DNS server, or the Zyxel Device itself. The
no command
resets the setting to its default value.
[no] second-dns-server
{ip | interface_name
{1st-dns | 2nd-dns |
3rd-dns} | ZyWALL}
Sets the second DNS server to the specified IP address, the specified
interface’s first, second, or third DNS server, or the Zyxel Device itself. The
no
command resets the setting to its default value.
[no] third-dns-server
{ip | interface_name
{1st-dns | 2nd-dns |
3rd-dns} | ZyWALL}
Sets the third DNS server to the specified IP address, the specified
interface’s first, second, or third DNS server, or the Zyxel Device itself. The
no
command resets the setting to its default value.
