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.
