PPPoE Ignores Physical Interface Link Status
Resolution
Issue
When a device's physical interface is set manually down, or is physically disconnected with a configuration of PPPoE, the device will continually log PPPoE related errors every 3 seconds.
Example Log events
| initiate | ethernet1/4 | 0 | 0 | general | informational | PPPoE session was initiated for user:rwwa on interface:ethernet1/4 |
| connect-fail | ethernet1/4 | 0 | 0 | general | informational | PPPoE session failed to connect for user:foo on interface:ethernet1/4. Reason: No PPPoE Offer received |
Resolution
This is the expected behavior for the PPPoE configured interfaces. A manual interface down or an unplugged cable can be a temporary state, such as for maintenance or when a cable is being swapped, the logic is to keep trying so if the condition is rectified. Once the link is available, we connect as quickly as possible.
To avoid these log events from being present in the System logs (Monitor > System), disable the PPPoE instance from the UI or CLI.
Note: Versions of PAN-OS previous to 5.0.x do not include configuration options for PPPoE.
