Conguring a next-bootstrap server
The next-bootstrap-server command species the IP address of the next server the client should use for boot up.
device(config-dhcp-cabo)# next-bootstrap-server 10.2.5.44
Syntax: next-bootstrap-server address
Conguring the TFTP server
The tftp-server command species the address or name of the TFTP server to be used by the DHCP clients.
To congure a TFTP server by specifying its IP address, enter a command similar to the following.
device(config-dhcp-cabo)# tftp-server 10.7.5.48
To
congure a TFTP server by specifying its server name, enter a command similar to the following.
device(config-dhcp-cabo)# tftp-server tftp.domain.com
Syntax:tftp-server { address | name server-name }
• address is the IP address of the TFTP server.
• name congures the TFTP server specied by server-name.
If DHCP options 66 (TFTP server name) and 150 (TFTP server IP address) are both congured, the DHCP client ignores option 150
and tries to resolve the TFTP server name (option 66) using DNS.
Conguring a vendor type and conguration value for a DHCP client
The vendor-class command species the vendor type and conguration value for a DHCP client.
device(config-dhcp-cabo)# vendor class ascii waikiki
Syntax: vendor-class { ascii | ip | hex } value
Conguring X Window System Display Manager IP addresses (Option 49)
Option 49 species a list of IP addresses of systems that are running the X Window System Display Manager and are available to the
client.
Option 49 is described in RFC 2132. The X Window client is a DHCP client in a network that solicits conguration information by
broadcasting a DHCP discovery packet on bootup or when the DHCP client is enabled. The DHCP server provides the IP addresses of
systems running the X Window System Display Managers available in the network in their preferred order as part of the DHCP oer
message.
On receipt of a discovery packet from the client, a DHCP oer must be sent back. Option 49 must be added with the IP addresses of
systems running the X Window System Display Manager in the network, along with other mandatory options. You can congure a
maximum of three IP addresses in a DHCP server pool.
NOTE
Option 49 is ignored if the client is a non-X Window client.
1. Enter global conguration mode.
2. Enter the DHCP server pool conguration mode.
3. Enter the xwindow-manager command along with the IP addresses of the X Window Display Manager separated by spaces.
