Description
Enter the DHCP private option value to be used when VLAN
discovery is set to custom
Enables or disables the VLAN Ethernet packet filtering on the
phone to prevent TCP/IP stack overflows caused by invalid or
excessive data.
If enabled, the phone will use the LLDP protocol to communicate
with the network switch for certain network parameters. Most
often this will be used to set the VLAN that the phone should use
for voice traffic. It also reports the power management
requirements to the switch.
If enabled, the phone will use CDP-compatible signaling to
communicate with the network switch for certain network
parameters. Most often this will be used to set the VLAN that the
phone should use for voice traffic, and for the phone to
communicate its PoE power requirements to the switch.
If set to disabled, no VLAN discovery through DHCP. If set to
Fixed, use predefined DHCP vendor-specific option values of
128, 144, 157, and 191. If one of these is used, VLAN Option is
ignored. If set to Custom, use the number specified for the VLAN
Option as the DHCP private option value.
The DHCP private option (when VLAN Discovery is set to
