Configure an Aggregate Interface Group (SCM)

1. Log in to Strata Cloud Manager.
2. Select ManageConfigurationNGFW and Prisma AccessDevice SettingsInterfacesEthernetConfigurationNGFW and Prisma AccessDevice SettingsInterfacesEthernet and select the Configuration Scope where you want to create the aggregate interface group.

   Select a firewall from your Folders or select Snippets to configure the aggregate interface group in a snippet.

   If you select a folder or select a snippet, you create an aggregated interface group variable that must be assigned at the device level.
3. Configure the interfaces that you want to add to the aggregate interface group.

   Among the interfaces assigned to any particular aggregate group, the hardware media can differ (for example, you can mix fiber optic and copper) but the bandwidth and interface type must be the same.

   • Configure a Layer 2 Interface
   • Configure Layer 3 Interfaces
   • Configure an Aggregate Ethernet Interface Variable
4. Add the aggregate interface.

   • Folders and Snippets—Add Interface and select Aggregate Group.
   • Firewalls—Add and Add Aggregation Group.
5. Enter the Interface Name.

   By default, all aggregate interface groups are prefixed with ae.
6. (Optional) Enter a Description.
7. Select the Interface Type.

   The aggregate interface group type must match the Ethernet interface type (Layer 2 or Layer 3).
8. (Firewall only) Add the Ethernet Interfaces you created in the previous step.

   You can only add Ethernet interfaces to an aggregate interface group from the firewall Configuration Scope.
9. (Layer 3 only) Configure the aggregate interface group IP settings.

   1. Select the aggregate interface group IP Type.

   • Static IPv4 Address.
     Add the IPv4 IP addresses for the interfaces in the aggregate interface group.
   • DHCP Client activation on the aggregate interface group.
     See Configure an Interface as a DHCPv4 Client for more information on configuring the aggregate interface group as a DHCP client.
10. (Optional) Configure the LACP settings.

    Configure this setting only if you want to enable LACP for the aggregate group.

    1. Enable LACP.
    2. Set the LACP Mode.

       • Passive (default)—The firewall just responds.
       • Active—The firewall queries peer devices.

       Set one LACP peer to active and the other to passive. LACP can’t function if both peers are passive. The firewall can’t detect the mode of its peer device.
    3. Set the Transmission Rate for LACP queries and response exchanges.

       Base your selection on how much LACP processing your network supports and how quickly LACP peers must detect and resolve interface failures.

       • Slow (default)—Every 30 seconds.
       • Fast—Every second.
    4. Enable Fast Failover to enable failover to a standby interface in less than 1 second.

       This option is disabled by default and the firewall uses the IEEE 802.1ax standard for failover processing, which takes at least 3 seconds.

       Enable Fast Failover in deployments where you might lose critical data during the standard failover interval.
    5. Specify the System Priority to determine the failover priority in the event of LACP peers that have nonmatching port priority values.

       Default is 32,768; range is 1-65,535. The value of the peer with the lower system priority number overrides the other peer.
11. Save.
12. Push Config to push your configuration changes.
