Table 70 DHCP Extended Options OPTION NAME Time Offset CODE 2 Time Server 4 NTP Server 42 TFTP Server Name 66 Bootfile 67 SIP Server 120 VIVC 124 DESCRIPTION This option specifies the offset of the client's subnet in seconds from Coordinated Universal Time (UTC). This option specifies a list of Time servers available to the client. This option specifies a list of the NTP servers available to the client by IP address. This option is used to identify a TFTP server when the "sname" field in the DHCP header has been used for DHCP options. The minimum length of the value is 1. This option is used to identify a bootfile when the "file" field in the DHCP header has been used for DHCP options. The minimum length of the value is 1. This option carries either an IPv4 address or a DNS domain name to be used by the SIP client to locate a SIP server. Vendor-Identifying Vendor Class option VIVS 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. 125 Vendor-Identifying Vendor-Specific option CAPWAP AC DHCP clients and servers may use this option to exchange vendor-specific information. 138 CAPWAP Access Controller addresses option TFTP Server The Control And Provisioning of Wireless Access Points Protocol allows a Wireless Termination Point (WTP) to use DHCP to discover the Access Controllers to which it is to connect. This option carries a list of IPv4 addresses indicating one or more CAPWAP ACs available to the WTP. 150 The option contains one or more IPv4 addresses that the client may use. The current use of this option is for downloading configuration from a VoIP server via TFTP; however, the option may be used for purposes other than contacting a VoIP configuration server. 10.4 PPP Interfaces Use PPPoE/PPTP interfaces to connect to your ISP. This way, you do not have to install or manage PPPoE/PPTP software on each computer in the network. UAG Series User's Guide 168

DHCP Extended Options
OPTION NAME
CODE
DESCRIPTION
Time Offset
2
This option specifies the offset of the client's subnet in seconds from
Coordinated Universal Time (UTC).
Time Server
4
This option specifies a list of Time servers available to the client.
NTP Server
42
This option specifies a list of the NTP servers available to the client by IP
address.
TFTP Server Name
66
This option is used to identify a TFTP server when the “sname” field in the
DHCP header has been used for DHCP options. The minimum length of the
value is 1.
Bootfile
67
This option is used to identify a bootfile when the “file” field in the DHCP
header has been used for DHCP options. The minimum length of the value is
1.
SIP Server
120
This option carries either an IPv4 address or a DNS domain name to be used
by the SIP client to locate a SIP server.
VIVC
124
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.
VIVS
125
Vendor-Identifying Vendor-Specific option
DHCP clients and servers may use this option to exchange vendor-specific
information.
CAPWAP AC
138
CAPWAP Access Controller addresses option
The Control And Provisioning of Wireless Access Points Protocol allows a
Wireless Termination Point (WTP) to use DHCP to discover the Access
Controllers to which it is to connect. This option carries a list of IPv4 addresses
indicating one or more CAPWAP ACs available to the WTP.
TFTP Server
150
The option contains one or more IPv4 addresses that the client may use. The
current use of this option is for downloading configuration from a VoIP server
via TFTP; however, the option may be used for purposes other than contacting
a VoIP configuration server.
