Last Modified: Oct 17, 2023

Affected Product(s):
BIG-IP Install/Upgrade(all modules)

Known Affected Versions:
11.1.0, 11.2.0, 11.2.1, 11.3.0, 11.4.0, 11.4.1, 11.5.0, 11.5.1, 11.5.2, 11.5.3, 11.5.4, 11.5.5, 11.5.6, 11.5.7, 11.5.8, 11.5.9, 11.5.10, 11.6.0, 11.6.1, 11.6.2, 11.6.3, 11.6.3.1, 11.6.3.2, 11.6.3.3, 11.6.3.4, 11.6.4, 11.6.5, 11.6.5.1, 11.6.5.2, 11.6.5.3, 12.0.0, 12.0.0 HF1, 12.1.0 HF1, 12.0.0 HF2, 12.1.0 HF2, 12.0.0 HF3, 12.0.0 HF4, 12.1.1 HF1, 12.1.1 HF2, 12.1.2 HF1, 12.1.2 HF2

Fixed In:
12.1.0

Opened: Nov 01, 2013

Severity: 3-Major

Symptoms

If a copper SFP module is installed and a configuration is loaded which sets that module's speed and duplex, this configuration might fail to load. The /var/log/ltm file shows an error similar to the following and the config fails to load. 01070318:3: The requested media for interface 1.1 is invalid.

Impact

The upgrade fails after booting into TMOS for the first time.

Conditions

The system being upgraded has a copper SFP module installed in order to encounter this issue. There are two ways to arrive at this state: when upgrading and at runtime. This runtime error and its workaround is covered in K14556: Copper 1 Gbps modules configured with media other than the 'auto' setting may not function :: https://support.f5.com/csp/article/K14556. When applying a UCS from a previous version of TMOS, this condition can also be triggered.

Workaround

To work around this issue, edit /config/bigip_base.conf so that the lines specifying the 'media-sfp' setting are set to 'auto', similar to the following example. Once all interfaces using a non-auto setting are changed, the configuration should load. net interface 1.1 { media-sfp auto }

Fix Information

Upgrades now complete successfully for copper 1 Gbps modules configured with media other than the 'auto' setting.
