Status messages for IGMP snooping are to be found under the following paths:
WEBconfig: LCOS menu tree / Status / LAN bridge statistics / IGMP snooping
- Operating Indicates whether IGMP snooping is activated or deactivated.
- IPv4 packets Shows the number of IPv4 multicast packets received at all ports, whether they were IGMP packets or not.
- Data packets Shows the number of intact IPv4 multicast packets received at all ports and which were not IGMP packets.
- Control packets Shows the number of intact IGMP packets received at all ports.
- Bad packets
Shows the number of damaged data or IGMP packets received at all ports.
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.
