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.
The upgrade fails after booting into TMOS for the first time.
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.
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 }
Upgrades now complete successfully for copper 1 Gbps modules configured with media other than the 'auto' setting.
