Setting the 802.1p priority for IGMP messages
About the 802.1p priority for IGMP messages
When congestion occurs on outgoing ports of the Layer 2 device, it forwards IGMP messages in their 802.1p priority order, from highest to lowest. You can assign a higher 802.1p priority to IGMP messages that are created or forwarded by the device.
Restrictions and guidelines
