PA-7000 Series Firewall LPC Support for Per-Virtual System Paths to Logging Servers
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 platforms, 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.
To configure the LPC for per-virtual system logging services, see Configure a PA-7000 Series Firewall for Logging Per Virtual System. For information about the LPC itself, see the PA-7000 Series Hardware Reference Guide.
