Configuration Parameters Appendix A Additional Configuration Methods, Parameters, and Procedures Table A-1 Network Parameters (continued) Parameter OpFlags Description Enables or disables various features on the phone. Usage Bit map, as follows: • Bit 0 (mask 0x1)-If 1, ignore the DHCP-assigned TFTP file name and use the following file name when using TFTP for configuring: ffxxxxxxxxxxxx (Cisco IP Phone 7902G) or ldxxxxxxxxxxxx (Cisco IP Phone models 7905G/7912G), where each xx is the two-digit lowercase hexadecimal representation of each integer in the phone's MAC address. • Bit 1 (mask 0x2)-If the phone is configured to use static IP (that is, the router and gateway addresses are statically assigned), set to 1 to prevent probing at boot time. Otherwise, the phone probes the route/gateway address to determine if there is network connectivity. • Bit 2-Reserved for future use. • Bit 3 (mask 0x8)-If 1, do not request DHCP option 150 in the DHCP DISCOVERY message. • Bit 4 (mask 0x10)-If 1, assume operation under VLAN. (The VLAN ID is specified in the VLANSetting parameter.) • Bit 5 (mask 0x20)-If 1, turn off VLAN IP encapsulation. • Bit 6 (mask 0x40)-If 1, do not perform CDP1 discovery. • Bit 7 (mask 0x80)-If 1, do not allow web configuration of the phone. • Bit 8 (mask 0x100)-Not used on the Cisco IP Phone 7905G. On the Cisco IP Phone 7902G, if set to 1, the IP address cannot be refreshed through an HTTP request.
