Any configuration changes made locally on the switch won't be synchronized with Sophos Central. We recommend making changes from the Sophos Central control panel instead.

IP Settings

The IP Setting screen contains fields for assigning IP addresses. IP addresses are either defined as static or are retrieved using the Dynamic Host Configuration Protocol (DHCP). DHCP assigns dynamic IP addresses to devices on a network. DHCP ensures that network devices can have a different IP address every time the device connects to the network.

To access the page, click IP Settings under the System menu.

IPv4 management

You can see the current IPv4 IP setting in this page. Press the edit button to edit the IPv4 address setting.

Select whether to you wish to enable Static, DHCP or BOOTP for auto configuration. If you would like to setup the Static IP address on your device , enter the information for the VLAN ID, IP address, and Subnet Mask.

Warning

If the device fails to retrieve an IP address through DHCP, the default IP address is 172.16.16.239 and the factory default subnet mask is 255.255.255.0.

Note

You can assign static IP addresses to a maximum of four VLAN interfaces, including the default VLAN, which may already have a static IP address.

Option Description
Dynamic IP Address (DHCP) Enables the IP address to be configured automatically by the DHCP server. Select this option if you have a DHCP server that can assign the Switch an IP address, subnet mask, default gateway IP address, and a domain name server IP address automatically. Selecting this field disables the IP Address, Subnet Mask, and Gateway fields.
Static IP Address Allows the entry of an IP address, subnet mask, and a default gateway for the Switch. Select this option if you don't have a DHCP server or if you wish to assign a static IP address to the Switch.
VlanID Define the VLAN ID for which the network policy is defined. The range of the VLAN ID is from 1 to 4094.
IP Address This field allows the entry of an IPv4 address to be assigned to this IP interface. Enter the IP address of y our Switch in dotted decimal notation. The factory default value is: 172.16.16.239.
Subnet Mask A subnet mask separates the IP address into the network and host addresses. A bitmask that determines the extent of the subnet that the Switch is on. This should be labeled in the form: xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimals) between 0 and 255. The value should be 255.0.0.0 for a Class A network, 255.255.0.0 for a Class B network, and 255.255.255.0 for a Class C network, but custom subnet masks are allowed. Enter the IP subnet mask of your Switch in dotted decimal notation. The factory default value is: 255.255.255.0.

IPv6 management

IPv6 is an upgraded version to IPv4, providing more available IP addresses as well as other benefits. To access the switch over an IPv6 network you must first configure it with IPv6 information (IPv6 prefix, prefix length). To configure IPv6 for the Switch, select whether to you wish to enable Stateful DHCPv6, Stat eless DHCPv6 , or Static . Next, enter the information for the IP address, and Prefix Length.

Option Description
DHCPv6 Select whether you wish to enable Static, Stateless DHCPv6, or Stateful DHCPv6
Stateful DHCPv6 Stateful DHCPv6 is used to pass out addressing and service information in the same way that DHCP is used in IPv4. Use this option to set the IPv6 address for the IPv6 network interface in Auto Configuration. The Switch will automatically generate and use a globally unique IPv6 address based on the network prefix and its Ether net MAC address.
Stateless DHCPv6 Stateless DHCPv6 provides a host gains an address via an interface automatically "leasing" an address and does not require the establishment of an server to delve out address space. Stateless auto configuration allows a host to propose an address which will probably be unique (based on the network prefix and its Ethernet MAC address) and propose its use on the network. Because no server has to approve the use of the address, or pass it out, stateless auto configuration is simpler. Select this option if you do not have an IPv6 DHCP server that can assign the Switch an IPv6 address/prefix and a default gateway IP address.
Static Allows the entry of an IPv6 address/prefix and a default gateway for the Switch. Select this opti on if you wish to assign static IPv6 address information to the Switch.
IPv6 Address This field allows the entry of an IPv6 address/prefix to be assigned to this IP interface.
Prefix Length IPv6 Prefix Length is used to identify how many bits of a Gobal Unicast IPv6 Address are there in network part. For example, in 2001:0DB8:0000:000b::/64, the number 64 is used to identify that the first 64 bits are in network part.

IPv4 Network

You can setup the multiple IPv4 address in this page. If you would like to setup the multiple Static IP address on your device, click the Add button.

Enter the information for the VLAN ID, IP address, and Subnet Mask.

Option Description
VlanID Define the VLAN ID for which the network policy is defined. The range of the VLAN ID is from 1 to 4094.
IP Address This field allows the entry of an IPv4 address to be assigned to this IP interface. Enter the IP address of your Switch in dotted decimal notation. The factory default value is: 172.16.16.239.
Subnet Mask A subnet mask separates the IP address into the network and host addresses. A bitmask that determines the extent of the subnet that the Switch is on. This should be labeled in the form: xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimals) between 0 and 255. The value should be 255.0.0.0 for a Class A network, 255.255.0.0 for a Class B network, and 255.255.255.0 for a Class C network, but custom subnet masks are allowed. Enter the IP subnet mask of your Switch in dotted decimal notation. The factory default value is: 255.255.255.0.

IPv 6 Network

You can setup the multiple IPv6 address in this page. If you would like to setup the multiple Static IP address on your device, click Add button.

Enter the information for the VLAN ID, IP address, Prefix Length and Choose the Address Type.

Option Description
VlanID Define the VLAN ID for which the network policy is defined. The range of the VLAN ID is from 1 to 4094.
Address This field allows the entry of an IPv6 address to be assigned to this IP interface.
Prefix Length IPv6 Prefix Length is used to identify how many bits of a Global Unicast IPv6 Address are there in network part. For example, in 2001:0DB8:0000:000b::/64, the number 64 is used to identify that the first 64 bits are in network part.
Address Type Unicast: Unicast IP address is standard globally unique unicast addresses (public IPv6 addresses) as in IPv6.
LinkLocal: Link local address is a network address that is valid only for communications within the network segment or the broadcast domain that the host is connected to.

DNS Server

DNS (Domain Name System) is used for mapping a domain name to its corresponding IP addresses and vice versa. Enter a DNS IP address in order to be able to use a domain name to access the Switch instead of using an IP address.
