Setting a Network Group Alias

About this task

A network group alias is a set of configurations consisting of host and network configurations. Network configurations are complete networks in the form of 192.168.10.0/24 or an IP address range in the form of 192.168.10.10-192.168.10.20. Host configurations are in the form of a single IP address, 192.168.10.23.

A network group alias can contain multiple definitions for a host, network, and IP address range. A maximum of eight (8) Host entries, eight (8) network entries and eight (8) IP addresses range entries can be configured inside a network group alias. A maximum of 32 network group alias entries can be created.

    Select an existing network group alias and click Edit to modify it.
  4. If you are creating a new network group alias, assign it a Name up to 32 characters to distinguish this alias configuration from others with similar attributes.

  5. Define the following network group alias parameters:
    Host Specify the Host IP address for up to eight IP addresses supporting network aliasing. Select the down arrow to add the IP address to the table.
    Network Specify the netmask for up to eight IP addresses supporting network aliasing. Subnets can improve network security and performance by organizing hosts into logical groups. Applying the subnet mask to an IP address separates the address into a host address and an extended network address. Select the down arrow to add the mask to the table.
  6. Within the Range table, use the + Add Row button to specify the Start IP address and End IP address for the alias range, or double-click on an existing alias range entry to edit it.
  7. Select OK when completed to update the network group alias settings.
    Select Reset to revert the screen to its last saved configuration.
