DHCP Commands
XSR CLI Reference Guide 15-101
next-server
This command specifies the server from which the initial boot file will be loaded. The server can
be designated either by IP address or hostname.
Syntax
next-server server [hostname | ip_address]
Syntax of the “no” Form
Use the no form of this command to remove the next‐server:
no next-server server [hostname | ip_address]
Mode
Any of the following command modes are available:
DHCP pool configuration: XSR(config-dhcp-pool)#
DHCP host configuration: XSR(config-dhcp-host)#
DHCP client class configuration: XSR(config-dhcp-class)#
Example
The following example specifies the IP address of a next‐server:
XSR(config-dhcp-pool)next-server 192.168.57.4
option
This command configures DHCP server options/extensions. DHCP Server provides a framework
for passing configuration data to hosts on a TCP/IP network. Configuration values and other
control data are carried in tagged data items stored in the options field of the DHCP message.
The data items are also called options or client extensions. The current set of XSR‐supported
DHCP options and BOOTP vendor extensions are described in
Table 15‐1 on page 102 and
generally in RFC‐2132. Default values are defined in RFC‐1122.
Depending on the client configuration inheritance, the command should be used from the proper
mode. If it is specified from multiple modes, an override mechanism chooses the innermost config
value, with host as innermost, then client‐class and pool as the most general.
Syntax

hostname Designation of the server by name.
ip_address Designation of the server by IP address.
code DHCP option code.
ascii string An ASCII character string. Strings containing space must be enclosed with quotes.
