Vendor Options - Overview
Vendor Options allows the SBC Edge to provide vendor parameters for a specific static DHCP client (i.e, SIP phones, engineering workstations, VPN users, etc.). The configuration values are specific to the phone or device being configured. For valid values, consult the manual that accompanied the phone/device.
The Vendor Specific Information is for Dynamic Host Configuration Protocol (DHCP) option 43 (defined here: http://tools.ietf.org/html/rfc2132#section-8.4). These options allows a client (phone or device) to indicate its vendor type, and the DHCP client and server to exchange vendor specific information.
The Vendor-Identifying Vendor Options are DHCP option 124/125 (defined here: http://tools.ietf.org/html/rfc3925).
