xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual config multicast port_flitering_mode Purpose Syntax Description Parameters Restrictions Used to configure the multicast packet filtering mode for ports. config multicast port_filtering_mode [|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. − 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. Example usage: To configure the multicast packet filtering mode for ports: DES-3800:admin#config multicast port_filtering_mode 15:1-15:4 forward_all_groups Command: config multicast port_filtering_mode 15:1-15:4 forward_all_groups Success. DES-3800:admin# delete fdb Purpose Syntax Description Parameters Restrictions Used to delete an entry to the Switch's forwarding database. delete fdb This command is used to delete a previous entry to the Switch's MAC address forwarding database. − The name of the VLAN on which the MAC address resides. − The MAC address that will be added to the forwarding table. Only Administrator or Operator-level users can issue this command. 85
