No. In an IGMPv3 network environment, the switch or router expects a cyclical signal from the IP Router. If no retriggered signal comes from the IPR/S, then the ports will be closed. These are safety-relevant aspects stored in the IP switch.
Solution: Either the network environment must be reset to IGMPv2, or the administrator must set the affected ports separately.
IP Router IPR/S 3.1.1 can be integrated into the IGMPv3 network environment without any problems.
