security, S3900 series Ethernet switches provide the following function:

multicast routing function is enabled.
z When the multicast routing function is disabled, the RAW socket used by the
multicast routing function is disabled.
This function is implemented in the following scenarios:
z Use the multicast routing-enable command to enable the multicast routing
function and enable the RAW socket used by the multicast routing function.
z Use the undo multicast routing-enable command to disable the multicast routing
function and disable the RAW socket used by the multicast routing function.
