Symptoms

Messages similar to the following appear in /var/log/ltm: info bcm56xxd: 012c0012:6: I2C muxes are not cleared. Problem with mux 224:

Impact

Changes in optic state may be ignored while I2C bus is unavailable.

Conditions

-- i5000/i7000/i10000 platforms. -- May be caused by a defective optic, rebooting/upgrading BIG-IP, removing and reinserting optics.

Workaround

For each SFP, perform the following procedure: 1. Unplug the optic. 2. Wait 10 seconds. 3. Plug optic back in. Note: This message might be caused by a defective optic. If error messages stop when one optic is removed, and error messages resume when the optic is inserted, replace that optic.

Fix Information

The I2C bus on i5000/i7000/i10000 platforms now resets the Mux controlling the I2C bus connected to the front panel optics.
