Last Modified: Dec 29, 2022

Bug Tracker

Affected Product:  See more info
F5OS Velos(all modules)

Known Affected Versions:
1.5.0

Fixed In:
1.5.1

Opened: Aug 18, 2022
Severity: 3-Major

Symptoms

Because configuration entries added to the internal ePVA hardware acceleration tables may become stuck, packets arriving from front panel ports may be handled by stale entries resulting in unexpected forwarding behavior. The stale entries may also prevent TMM from offloading new connections to ePVA.

Impact

Packets may be forwarded to unexpected destinations, and/or new connections are unable to be offloaded to ePVA.

Conditions

The most likely cause for entries to become stuck is either a reboot of tenant or restart of TMM while it has active connections offloaded to ePVA without also rebooting the entire appliance.

Workaround

Don't reboot or restart TMM without also rebooting the entire appliance.

Fix Information

Packets are behaving as expected.
