Configuring Source Interface for AOS-CX

Source interface allows you to configure a single source interface for a service so that all traffic routed through the switch is sent with the same IP address. The IP address is configured on the ports, LAGs, or VLANsVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. at the device level.

You can add, modify, or delete source interface configuration in Aruba Central (on-premises). At the group level, Aruba Central (on-premises) allows you to configure only the port or LAGLink Aggregation Group . A LAG combines a number of physical ports together to make a single high-bandwidth data path. LAGs can connect two switches to provide a higher-bandwidth connection to a public network. information for the interface. However, at the device level, you can also configure VLANs and IP address for the interface.

Aruba Central (on-premises) supports only Central and User-based tunneling source interfaces in the UI. However, in the MultiEdit mode, you can configure source interfaces for other protocols such as, DNSDomain Name System. A DNS server functions as a phone book for the intranet and Internet users. It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element., NTPNetwork Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network., and PTP. The source interfaces that you add in the MultiEdit mode (other than Central and User-based tunneling) will not appear in the Source Interface page at the device level.

Adding a Source Interface

To add a source interface, complete the following steps:

1. In the Network Operations app, select one of the following options:
   • To select a switch group in the filter:
     1. Set the filter to a group.
        

        The dashboard context for the group is displayed.

     2. Under Manage, click Devices > Switches.
     3. Click the AOS-CX or Config icon to view the switch configuration dashboard.
   • To select a switch in the filter:
     1. Set the filter to Global or a group containing at least one switch.
     2. Under Manage, click Devices > Switches.
        

        A list of switches is displayed in the List view.

     3. Click an AOS-CX switch under Device Name.
        

        The dashboard context for the switch is displayed.

     4. Under Manage, click Device.
        

        The AOS-CX UI configuration page is displayed.

2. Click System > Source Interface.

   The Source Interface page is displayed with a list of source interfaces that are configured.

3. In the Source Interface table, click the + add icon to add a source interface and configure the following parameters in the Create Source Interface page.

   When both Central and User-based tunneling source interfaces are added for a switch, the + add icon is disabled.

   Name	Description	Value
   Interface	The interface or the service name. You can configure only two interfaces at any given time.	Central or User-based tunneling
   Port/LAG	Type of interface you want to configure. The name of this field is applicable only at the group level. At the device level, the field name is Port/LAG/VLAN/Address.	At the group level—Port or LAG At the device level—Port, LAG, VLAN, or Address
   Port name	Port number for the source interface. Applicable when you select Port in the Port/LAG drop-down at the group level or Port/LAG/VLAN/Address drop-down at the device level.	Select a port from the drop-down. NOTE:   At the group level—Only the ports that have routing enabled at the group level are available in this drop-down. At the device level—Only the ports that have routing enabled and IP address configured on the ports at the device level are listed in this drop-down.
   LAG name	LAG name for the source interface. Applicable when you select Port in the Port/LAG drop-down at the group level or Port/LAG/VLAN/Address drop-down at the device level.	Select a LAG from the drop-down. NOTE:   At the group level—Only the LAGs that have routing enabled at the group level are available in this drop-down. At the device level—Only the LAGs that have routing enabled and IP address configured on the LAGs at the device level are listed in this drop-down.
   VLAN ID	VLAN ID for the source interface. NOTE:   Available only at the device level. Applicable when you select VLAN in the Port/LAG/VLAN/Address drop-down at the device level.

4. Click Save.

   The source interface information is displayed in the Source Interface table.

Editing a source interface

To edit a source interface, point to the row for the source interface, and click the edit icon. You can select only one source interface at a time for editing.

• When editing the Central interface, you cannot edit the interface type.
• When editing the User-based tunneling interface, you cannot edit the interface type and the VRF.

Deleting a source interface

To delete a source interface, point to the row for the source interface, and click the delete icon. Deleting source interface at device level and modifying configuration at group level will not add the source interface again on the device. You can select only one source interface at a time for deleting.
