We have a couple 1G TX SFPs installed in a 7280SR2K-48C6 in the 1/10G ports, not the 25G ports, and even when no cable is connected to the SFP, the link on the switch is still up. If we connect a cable to it, it works as normal, but removing the cable the link never goes down. This also means that MAC address tables don’t immediately clear as it thinks the interface is still up. Is this normal? I’ve not been able to find any documentation about this.
