Cisco IP Phone Administration Guide for Cisco CallManager 3.3, Cisco IP Phones 7902G/7905G/7912G
OL-6313-01
OpFlags Enables or disables various
features on the phone.
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 CDP
1
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.
