Setting 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.
You can set the 802.1p priority globally for all VLANs in IGMP-snooping view or for a VLAN in VLAN
view. For a VLAN, the VLAN-specific configuration takes priority over the global configuration.
