Bit Number Definition
0 If Bit 0 = 0, the TFTP configuration filename supplied by the DHCP server overwrites the default filename for
each Cisco ATA.
If Bit 0 = 1, the default Cisco ATA filename is always used.
1 If Bit 1 = 0, the Cisco ATA probes the static network router during the power-up process.
If Bit 1 = 1, static network router probing is disabled.
2Reserved.
3 If Bit 3=1, the Cisco ATA does not request DHCP option 150 in the DHCP discovery message; some DHCP
servers do not respond if option 150 is requested.
4 If Bit 4 = 1, the Cisco ATA use the VLAN ID specified in the VLANSetting parameter for VLAN IP encapsulation
(see the “VLANSetting” section on page 5-18).
5 If Bit 5=1, the Cisco ATA disables VLAN IP encapsulation.
6 If Bit 6=1, the Cisco ATA does not perform CDP discovery.
7 If Bit 7=1, the Cisco ATA does not allow web-based configuration.
8-10 Reserved.
11 If Bit 11=0, the Cisco ATA requests the device hostname from the DHCP server.
