Configuring Network Interfaces with a Configuration Editor

Navigate to the Interfaces level in the configuration hierarchy.

1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
2. Next to Interfaces, click Configure or Edit.

From the [edit] hierarchy level, enter

edit interfaces interface-name

For information about interface names, see Network Interface Naming.

Create the new interface.

1. Next to Interface, click Add new entry.
2. Enter the name of the new interface in the Interface name box.

   Make sure the name conforms to the interface naming rules. For more information, see Network Interface Naming.

3. Click OK.

Create the basic configuration for the new interface.

1. Under Interface Name in the table, click the name of the new interface.
2. Enter values in the other fields on this page if warranted.

   All these entries are optional, but you need to set values for Clocking and Encapsulation in particular if the default values are not suitable.

Enter values for physical interface properties as needed. Examples include changes to the default values for physical encapsulation or MTU. For example:

set interface-name encapsulation ppp

Add values for interface-specific options.

Most interface types have optional parameters that are specific to the interface type.

1. Under Nested configuration, click Configure for the appropriate interface type.
2. In the interface-specific page that appears, enter the values you need to supply or change the default values.
3. When you are finished, click OK to confirm your changes or Cancel to cancel them and return to the previous page.

1. From the [edit interfaces interface-name] hierarchy level, type

   edit interface-options

2. Enter the statement for each interface-specific property for which you need to change the default value.

Add logical interfaces.

1. In the main Interface page for this interface, next to Unit, click Add new entry.
2. On the Unit page for logical interfaces that appears, type a number from 0 through 16384 in the Interface unit number box.
3. Enter values in other fields as required for your network.
4. To configure protocol family values if needed, under Family, click Configure next to the appropriate protocol.
5. To access additional subordinate hierarchies under Nested configuration, click Configure next to any parameter you want to configure.
6. When you are finished, click OK.

1. From the [edit interfaces interface-name] hierarchy level, type

   set unitlogical-unit-number

   Replace logical-unit-number with a value from 0 through 16384.

2. Enter additional values for properties you need to configure on the logical interface, such as logical encapsulation or protocol family.

Navigate to the Interfaces level in the configuration hierarchy.

1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
2. Next to Interfaces, click Edit.

From the [edit] hierarchy level, enter

edit interfaces ge-0/0/3

Select the Gigabit Ethernet interface ge-0/0/3.

In the Interface name column, click ge-0/0/3.

Configure a static ARP entry on logical unit 0 with the source address 10.1.1.1/24 on the ge-0/0/3 interface.

Set the IP address of the subnet node to 10.1.1.3 and the corresponding MAC address to 00:ff:85:7f:78:03.

To have the device reply to ARP requests from the node, use the publish option.

1. Under Unit, next to 0, click Edit.
2. Under Family, next to Inet, click Edit.
3. Under Address, next to 10.1.1.1/24, click Edit.
4. Next to Arp, click Add new entry.
5. In the Address box, type the IP address of the node—10.1.1.3.
6. Select the Publish check box.
7. From the Mac address type list, select Mac.
8. In the Mac box, type the MAC address 00:ff:85:7f:78:03 of node.
9. Click OK until you return to the Interfaces page.

1. Enter

   edit unit 0

2. Enter

   edit family inet address 10.1.1.1/24

3. Enter

   set arp 10.1.1.3 mac 00:ff:85:7f:78:03 publish
