Information
When the mac-flood-list with the min-speed option is used in combination with the restrict-flood
command, mac-flood-list command has higher priority than the restrict-flood command.
Therefore, all multicast frames matching the mac-address range specified using the mac-flood-list
command are flooded according to the mac-flood-list command. Only the multicast frames not
matching the mac-address range specified using the mac-flood-list command are flooded according to
the restrict-flood command.

Usage
Information
Mtrace is an IGMP protocol based on the Multicast trace route facility and implemented according to
the IETF draft “A trace route facility for IP Multicast” (draft-fenner-traceroute-ipm-01.txt). FTOS
supports the Mtrace client and transmit functionality.
As an Mtrace client, FTOS transmits Mtrace queries, receives, parses and prints out the details in the
response packet received.
