Affected Product(s):
F5OS Velos
Known Affected Versions:
F5OS-A 1.0.0, F5OS-A 1.0.1, F5OS-A 1.1.0, F5OS-A 1.1.1, F5OS-A 1.2.0
Opened: May 26, 2022 Severity: 3-Major
From F5OS-A 1.3.0 or later releases have new DAG capability to enable "dag-adjust" and "ipv6-prefix-length" settings in combination with BIG-IP tenant version 15.1.8 and later. If we downgrade F5OS-A 1.3.0 or later to older releases before F5OS-A 1.3.0 and have a BIG-IP tenant software version 15.1.8 or later, the platform creates duplicate service entries. Due to a mismatch in the DAG profile in the platform and tenant, there will be packet redirects.
Performance degrade due to packet redirects.
Downgrading F5OS-A 1.3.0 or later to any older release before F5OS-1.3.0 with BIG-IP tenant software version 15.1.8 or later.
Workaround steps: 1. Backup the tenant's configuration that experienced this issue -> https://support.f5.com/csp/article/K13132 2. Copy the configuration off the tenant to some other host 3. Take note of the affected tenant's partition configuration -> show running-config tenants tenant <name> 4. Delete the affected tenant in the partition 5. Recreate the tenant with the same configuration noted in step #3 6. Copy the tenant config backup taken in step #1 back to the tenant and reload the configuration
