Configure a PA-7000 Series Firewall for Logging Per Virtual System

For Traffic, HIP Match, Threat, and Wildfire log types, the PA-7000 Series firewall does not use service routes for SNMP Trap, Syslog and email services. Instead, the PA-7000 Series firewall Log Processing Card (LPC) supports virtual system-specific paths from LPC subinterfaces to an on-premise switch to the respective service on a server. For System and Config logs, the PA-7000 Series firewall uses global service routes, and not the LPC.
In other Palo Alto Networks models, the dataplane sends logging service route traffic to the management plane, which sends the traffic to logging servers. In the PA-7000 Series firewall, each LPC has only one interface, and data planes for multiple virtual systems send logging server traffic (types mentioned above) to the PA-7000 Series firewall LPC. The LPC is configured with multiple subinterfaces, over which the platform sends the logging service traffic out to a customer’s switch, which can be connected to multiple logging servers.
Each LPC subinterface can be configured with a subinterface name and a dotted subinterface number. The subinterface is assigned to a virtual system, which is configured for logging services. The other service routes on a PA-7000 Series firewall function similarly to service routes on other Palo Alto Networks platforms. For information about the LPC itself, see the PA-7000 Series Hardware Reference Guide.
If you have enabled multi virtual system capability on your PA-7000 Series firewall, you can configure logging for different virtual systems as described in the following workflow.
  1. Create a Log Card subinterface.
    1. Select NetworkInterfacesEthernet and select the interface that will be the Log Card interface.
    2. Enter the Interface Name.
    3. For Interface Type, select Log Card from the drop-down.
    4. Click OK.
  2. Add a subinterface for each tenant on the LPCs physical interface.
    1. Highlight the Ethernet interface that is a Log Card interface type and click Add Subinterface.
    2. For Interface Name, after the period, enter the subinterface assigned to the tenant’s virtual system.
    3. For Tag, enter a VLAN tag value.
      Make the tag the same as the subinterface number for ease of use, but it could be a different number.
    4. (Optional) Enter a Comment.
    5. On the Config tab, in the Assign Interface to Virtual System field, select the virtual system to which the LPC subinterface is assigned (from the drop-down). Alternatively, you can click Virtual Systems to add a new virtual system.
    6. Click OK.
  3. Enter the addresses assigned to the subinterface, and configure the default gateway.
    1. Select the Log Card Forwarding tab, and do one or both of the following:
      • For the IPv4 section, enter the IP Address and Netmask assigned to the subinterface. Enter the Default Gateway (the next hop where packets will be sent that have no known next hop address in the Routing Information Base [RIB]).
      • For the IPv6 section, enter the IPv6 Address assigned to the subinterface. Enter the IPv6 Default Gateway.
    2. Click OK.
  4. Commit your changes.
    Click OK and Commit.
  5. If you haven’t already done so, configure the remaining service routes for the virtual system.
