DHCP Parameters

Parameter

Description

'Enable DHCP'

■

[0] Disable (default)

■

[1] Enable

Note:

■

For the parameter to take effect, a device reset is required.

■

For a detailed description of DHCP, see DHCP-based Provisioning.

■

The parameter is a "hidden" parameter. Once defined and saved to flash memory, its value doesn't revert to default even if the parameter doesn't appear in the ini file.

[DHCP120OptionMode]

Enables the acceptance of DHCP Option 120 in DHCP responses sent by a DHCP server.

■

[0] = DHCP Option 120 is not supported and ignored if received in the DHCP response.

■

[1] = (Default) DHCP Option 120 is supported and if received, the device adds the SIP server information to the Proxy Set.

[DHCPSpeedFactor]

Defines the device's DHCP renewal speed for a leased IP address from a DHCP server.

■

[0] = Disable

■

[1] = (Default) Normal

■

[2] to [10] = Fast

When set to 0, the DHCP lease renewal is disabled. Otherwise, the renewal time is divided by this factor. Some DHCP-enabled routers perform better when set to 4.

Note: For the parameter to take effect, a device reset is required.
