Used to configure the multicast packet filtering mode for ports.
config multicast port_filtering_mode [<portlist>|all]
[forward_all_groups | forward_unregistered_groups |
filter_unregistered_groups]
The config multicast port_filtering_mode command configures the
multicast packet filtering mode for all ports.
<portlist> − Specifies a range of ports to be configured.
all – Specifies that all ports will be configured.
forward_all_groups- In this mode frames destined for group MAC
addresses are forwarded according to the VLAN rule.
forward_unregistered_groups- In this mode, if the Group MAC
Address Registration entries exist in the Multicast Table, frames
destined for the corresponding Group MAC addresseses are
forwarded, only on ports identified in the member port set. If the
Group MAC address does not exist in the Multicast Table the frames
are forwarded according to the VLAN rule.
filter_unregistered_groups- In this mode frames destined for group
MAC addresses are forwarded only if this type of forwarding is
explicitly permitted by a Group Address entry in the Multicast Table.
In other words, if the Group MAC address does not exist in the
Multicast table, the packets are dropped.
Only Administrator or Operator-level users can issue this command.
DES-3800:admin#config multicast

Command: config multicast port_filtering_mode
15:1-15:4 forward_all_groups

DES-3800:admin#
Used to delete an entry to the Switch's forwarding database.
delete fdb <vlan_name 32> <macaddr>
This command is used to delete a previous entry to the Switch's MAC address
forwarding database.
<vlan_name 32> − The name of the VLAN on which the MAC address resides.
<macaddr> − The MAC address that will be added to the forwarding table.
Only Administrator or Operator-level users can issue this command.
