Have you considered any security implications of enabling IGMP Querier functionality on the SG200-50P switch?

 - Increased risk of multicast-based attacks: If IGMP Querier functionality is enabled on the SG200-50P switch, it will send IGMP queries to the network to learn which devices are interested in receiving multicast traffic. Attackers can potentially use this information to launch multicast-based attacks, such as flooding the network with multicast traffic, which can cause denial-of-service (DoS) conditions and affect network performance.

Increased risk of unauthorized access: IGMP Querier functionality can also reveal the presence of devices on the network that may not be authorized to receive multicast traffic. This can increase the risk of unauthorized access to the network and potentially compromise network security.

Increased risk of network instability: Enabling IGMP Querier functionality on the SG200-50P switch can also result in network instability if there are devices on the network that are not IGMP-compliant. These devices may not respond to IGMP queries, leading to multicast traffic being forwarded to ports that do not need it, causing network congestion and instability.

To mitigate these security risks, it is recommended to enable IGMP Querier functionality only when necessary and to configure it correctly with appropriate security measures, such as access control lists (ACLs) and network segmentation. It is also important to ensure that all devices on the network are IGMP-compliant and that security patches and updates are applied regularly to the switch to address any potential vulnerabilities.
