Use DHCP

DHCP is an acronym for ‘Dynamic Host Configuration Protocol’. Its function is particularly useful when connecting to medium size or larger networks, such as the Internet. When this option is selected, your ServSwitch CX with IP will attempt to locate a DHCP server on the network. If such a server is located, it will supply three things to the ServSwitch CX with IP: an IP address, an IP network mask (also known as a Subnet mask) and a Gateway address. These are not usually granted permanently, but on a ‘lease’ basis for a fixed amount of time or for as long as the ServSwitch CX with IP remains connected and switched on. Discover allocations.

IP Address

This is the identity of the ServSwitch CX with IP within a network. The IP address can be thought of as the telephone number of the ServSwitch CX with IP. Unlike the MAC address, the IP address can be altered to suit the network to which it is connected. It can either be entered manually or configured automatically using the DHCP option. When the DHCP option is enabled, this entry is unavailable.

Net Mask

Also often called the ‘subnet-mask’, this value is used alongside the IP address to help define a smaller collection (or subnet) of devices on a network. In this way a distinction is made between locally connected devices and ones that are reachable elsewhere, such as on the wider Internet. This process helps to reduce overall traffic on the network and hence speed up connections in general.

Gateway

This is the address of the device that links the local network (to which the ServSwitch CX with IP is connected) to another network such as the Internet. Usually this is a network switch or router and it will be used whenever a device to be contacted lies outside the local network.

VNC Port

This is the logical link through which communications with a remote VNC viewer will be channelled (see What is a port?). The default setting is 5900 which is

a widely recognised port number for use by VNC software. However, in certain circumstances it may be advantageous to alter this number - see Security issues with ports for more details.

Note: The VNC port and HTTP port can be set to the same port number in order to simplify router and firewall configuration. If this is done then the ServSwitch CX with IP will “listen” for both types of traffic on the single port.

HTTP Port

This is the logical link through which communications with a remote web browser will be channelled. The default setting of 80 is an established standard for web (HTTP – HyperText Transfer Protocol) traffic though this can be changed to suit your local network requirements.

Clear IP Access Control

This option removes all entries from the IP access control feature within the ServSwitch CX with IP. The IP access control feature (configurable by a global admin user) allows certain network address ranges to be denied access to the ServSwitch CX with IP. If set incorrectly, it is possible to exclude all network users and so this option provides an emergency recovery point.
