Network Service Alias

A network service alias is a set of configurations that consist of protocol and port mappings. Both source and destination ports are configurable. For each protocol, up to 2 source port ranges and up to 2 destination port ranges can be configured. A maximum of 4 protocol entries can be configured per network service alias.

Use a service alias to associate more than one IP address to a network interface, providing multiple connections to a network from a single IP node.

Network Service Alias can be used in the following location to substitute protocols and ports:

To edit or delete a service alias configuration:

Go to Configuration > Devices.
Select RF Domain from the options on left-hand side of the UI, and then go to the Network Service Alias tab.
Select Edit to modify the attributes of an existing policy or Delete to remove obsolete policies from the list of those available. Select Add to create a new Network Service Alias.
If adding a new Network Service Alias, provide it a name of up to 32 characters.

Note
The Network Service Alias Name always starts with a dollar sign ($).

Within the Range field, use the + Add Row button to specify the Start IP address and End IP address for the service alias range or double-click on an existing service alias range entry to edit it.

Protocol	Specify the protocol for which the alias has to be created. Use the drop-down menu to select the protocol (eigrp, gre, icmp, igmp, ip, vrrp, igp, ospf, tcp and udp). Select other if the protocol is not listed. When a protocol is selected, its protocol number is automatically selected.
Source Port (Low and High)	Use this field only if the protocol is tcp or udp. Specify the source ports for this protocol entry. A range of ports can be specified. Select the Enter Range button next to the field to enter a lower and higher port range value. Up to eight (8) such ranges can be specified.
Destination Port (Low and High)	Use this field only if the protocol is tcp or udp. Specify the destination ports for this protocol entry. A range of ports can be specified. Select the Enter Range button next to the field to enter a lower and higher port range value. Up to eight (8) such ranges can be specified.

Select OK when completed to update the network service alias rules. Select Reset to revert the screen back to its last saved configuration.
