Specifications

Note: Private IPv4 addresses are used for example only

Each installation's IP addresses will be different from the example IP addresses but they

are used here only to illustrate how setup is done. Also, these addresses are private IPv4

addresses and in reality an ISP would use public IPv4 addresses instead.

We first add the gateway IPv4 address object which we will call wan_gw:

Device:/> add Address IP4Address wan_gw Address=10.5.4.1

This is the address of the ISP's gateway which is the first router hop towards the public Internet. If

this IP object already exists, it can be given the IP address with the command:

Device:/> set Address IP4Address wan_gw Address=10.5.4.1

Now use this object to set the gateway on the G2 interface which is connected to the ISP:

Device:/> set Interface Ethernet G2 DefaultGateway=wan_gw

Next, set the IP object G2_ip which will be the IPv4 address of the interface connected to the ISP:

Device:/> set IP4Address InterfaceAddresses/G2_ip Address=10.5.4.35

Note: Qualifying the names of IP objects in folders

On initial startup of the X8, cOS Core automatically creates and fills the

InterfaceAddresses folder in the cOS Core address book with Ethernet interface related

IPv4 address objects.

When an IP address object which is located in a folder is specified in the CLI, the object

name must be qualified with the name of its parent folder. For example, to reference the

address G2_ip, it must be qualified with the folder name InterfaceAddresses so it

becomes InterfaceAddresses/G2_ip.

If an object is not contained in a folder and is at the top level of the address book then no

qualifying parent folder name is needed.

Now, set the IP object G2_net which will be the IP network of the connecting interface:

Device:/> set IP4Address InterfaceAddresses/G2_net Address=10.5.4.0/24

It is recommended to verify the properties of the G2 interface with the command:

Device:/> show Interface Ethernet G2

The typical output from this will be similar to the following:
