Fixed In:
12.1.1

Opened: Mar 18, 2016
Severity: 3-Major

Symptoms

When non F5 optics is used for front switch ports, the LCD and /var/log/ltm will display some warning message. But the alarm LED may not reflect that.

Impact

The alarm LED may not reflect the warning.

Conditions

This is caused by a race condition. When a blade comes up and decides its role as a primary blade or a secondary blade, it will clear the alarm LED. So the last blade coming up may have its alarm LED in the right state, but the blades that came up earlier may have their alarm LEDs cleared.

Workaround

None.

Fix Information

The problem is fixed in TMOS v12.1.1.
