Port status

This table shows all port-related statistics.

• Router port Shows whether the port is currently in use as a router port or not, irrespective of whether this status was configured statically or learned dynamically.
• IPv4 packets Shows the number of IPv4 multicast packets received at this port, whether they were IGMP packets or not.
• Data packets Shows the number of intact IPv4 multicast packets received at this port and which were not IGMP packets.
• Control packets Shows the number of intact IGMP packets received at this port.
• Bad packets Shows the number of damaged data or IGMP packets received at this port. Possible causes for damage to packets may be IP checksum errors or truncated packets.
  Note: For performance reasons, IP checksums are evaluated for IGMP packets only and not for the data portion of multicast packets. This is why packets with a faulty checksum in the TCP/UDP or IP header are not detected. These packets are counted as data packets.
