Configure Link Aggregation Control Protocol

Configure link aggregation in ESXi and KVM environments.

Link aggregation involves configuring a link aggregation interface group and configuring the Link Aggregation Control Protocol. An aggregate interface group uses IEEE 802.1AX link aggregation to combine multiple Ethernet interfaces into a single virtual interface that connects the firewall to another network device or firewall. This aggregate group increases bandwidth between peers by load-balancing traffic across the combined interfaces. It also provides redundancy; when one interface fails, the remaining interfaces continue supporting traffic.

By default, interface failure detection is automatic only at the physical layer between directly connected peers. However, if you enable the Link Aggregation Control Protocol, failure detection is automatic at the physical and data link layers even if the peers are directly connected. LACP also enables automatic failover to standby interfaces if you configured hot spares.

To configure an aggregate interface group and LACP, see Configure an Aggregate Interface Group.

Create an Aggregate Ethernet Interface using Panorama

Don't add Panorama VMs associated with virtual functions from the same physical function to the same Aggregate Ethernet interface. Doing so creates a loop. Create an Aggregate Ethernet interface:

Configure an Aggregate Ethernet interface:
1. Select Network>Interfaces>Ethernet and Add Aggregate Group.
2. In the field adjacent to the read-only Interface Name, enter a number to identify the aggregate group. The range is 1 to the maximum number of aggregate interface groups supported by the firewall.
3. For the Interface Type, select HA, Virtual Wire, Layer 2, or Layer 3.
4. Configure the remaining parameters for the Interface Type you selected.
5. Commit your changes.
After creating the aggregate interface, add links to it.

Add Links to the Aggregate Ethernet Interface

To add links to the Aggregate Ethernet interface:

On Panorama, aggregate an Ethernet interface to act as listener in passive mode for the peer. Select Network > Interface.
Select an Ethernet interface to act as a peer.
In the Aggregate Ethernet Interface screen, select LACP.
Click Enable LACP.
Ensure that the mode is Passive.
Click OK.
Commit your changes in Panorama.
Confirm the configuration change. Click Yes.

Create the Aggregate Ethernet Interface Using the CLI

Use the following CLI commands to create an Aggregate Ethernet interface:

admin@PA-VM# set network interface aggregate-ethernet
  ae1      ae1
  <value>  Aggregate interface name: ae1 - ae16

For example,

admin@PA-VM# set network interface aggregate-ethernet ae1

Associate a Secondary Interface Using the CLI

Use the following CLI commands to associate a secondary interface:

admin@PA-VM# set network interface ethernet ethernet1/1 aggregate-group
  ae1      aggregate-ethernet ae1
  <value>  Aggregate interface group

For example,

set network interface ethernet ethernet1/1 aggregate-group ae1

Display the Interface Configuration Using the CLI

Use the following CLI commands to display the interface configuration:

admin@PA-VM> show interface all
