Q
Can I downgrade the firmware after upgrading it to a Device-Lock version?
A
For IGMP Filtering, you can config Maximum 10 Profiles, each Profile you can config Maximum 10 multicast groups.
- "Deny” means drop
- "Permit” means allow
When filtering on a specific port, it will check the Filtering Table and only allow multi-cast in its range to “Permit”. Thus, you should filter for downlink ports only. When IGMP filtering isenabled, it will activate the global config on the switch. Once you add a specific profile to the interface, the filtering process will start. At that point, IGMP Snooping will depend on the IGMP Filtering rules for multi-cast traffic allow or drop.
