Last Modified: Aug 26, 2024

Affected Product(s):
F5OS F5OS-A(all modules)

Fixed In:
F5OS-A 1.7.0, F5OS-A 1.5.2, F5OS-A 1.5.1

Opened: Jun 28, 2023

Severity: 1-Blocking

Symptoms

On r2000 and r4000 platforms, we can create a LAG as type LACP with a BIG-IP tenant. Later, when the datapath is up and running, if we change the LAG type to Static, the datapath on the tenant is broken. The platform sends the state of the members of the LAG as DOWN and hence LAG is DOWN on the BIG-IP tenant.

Impact

Datapath is completely broken while using the LAG configured.

Conditions

When LAG type is changed from LACP to Static.

Workaround

Bringing the DOWN members of the LAG back to UP by below configurations 1. interfaces interface <ifc name> config admin disable This will make interface to DOWN state and then move back to enabled state. 2. interfaces interface <ifc name> config admin enable

Fix Information

Datapath no longer breaks when changing the LAG type from LACP.
