Select the Aggregate Group you just defined. Consider one example where each tenant's traffic egresses the firewall where the next hop is an ISP router. For the aggregate group, create a subinterface that uses a static IP address. Select the Link Speed , Link Duplex , and Select Network Interfaces Ethernet , highlight the aggregate interface, such as ae1, and click Add Subinterface at the bottom of the screen. Configure trunking. I configured LACP for two ports connected from a Palo Alto firewall to a Cisco switch. Click on the name of the port ethernet1/7 and select the following: Interface Type: Aggregate Ethernet. This allows a Palo Alto firewall to act as the default gateway for a Layer. Current Version: 9.1. Since PAN-OS version 6.1 the Palo Alto Networks firewall supports LACP, the Link Aggregation Control Protocol which bundles physical links to a logical channel. L1 Bithead.

Environment Alternatively, for the aggregate group, create a subinterface that uses DHCP to get its address. A Layer 3 aggregated link has been created between the Palo Alto Firewall (Interface ae1 on each firewall) and the Cisco 4507R+E Switch (Port-Channel 1 & 2). PAN supports sub-interfaces on aggregate interfaces. Palo Alto Networks Predefined Decryption Exclusions. We currently have a L3 interface on our core switch that is cabled to a L3 interface on each firewall which serves as the "inside" interface. Go to Network > Interface and click on Add Aggregate Group. Select Network Interfaces Ethernet , highlight the aggregate interface, such as ae1, and click Add Subinterface at the bottom of the screen. Open the interface configuration. Access to config mode and enter the command interface FastEthernet0/2 to enter this port. Network > Interfaces; Aggregate Ethernet (AE) Interface Group; Download PDF. Create Untagged subinterfaces and assign them a different virtual router and zone. For Interface Name , enter a number after the period, such as 107. Is there a way to create a sub-interface via CLI? Setting up a new physical interface can be cumbersome because you first have to get them cabled up and then you even need to be lucky enough to have an inter. Navigate to the IPv4 tab.

Palo Alto calls it "Aggregate Interface Group" while Cisco calls it EtherChannel or Channel Group. 1. Enter the VLAN Tag to differentiate between the subinterfaces. Exclude a Server from Decryption for Technical Reasons. Select From the WebGUI, go to Network > Interfaces link. Aggregate Group: select ae1 just created. However, it is down on the Passive Firewall Passive Link State ( Under Device> High Availability> General > Active/Passive Settings) is enabled on both firewalls and members of the AE Interface are up on the Passive Firewall. 'ish. Go to Interfaces on the left pane. Configure the subinterface.
