Switching Commands 61
Link Trap Mode
This object determines whether or not to send a trap when link status
changes. The factory default is enabled.
STP Mode
The Spanning Tree Protocol Administrative Mode associated with the port or
port-channel (LAG). The possible values are:
Disable - Spanning tree is disabled for this port.
Enable - Spanning tree is enabled for this port.
Mbr Ports
A listing of the ports that are members of this port-channel (LAG), in slot/port
notation. There can be a maximum of eight ports assigned to a given port-
channel (LAG).
Port Speed
Speed of the port-channel port.
Type
This field displays the status designating whether a particular port-channel
(LAG) is statically or dynamically maintained.
Static - The port-channel is statically maintained.
Dynamic - The port-channel is dynamically maintained.
Active Ports
This field lists ports that are actively participating in the port-channel (LAG).
IGMP Snooping Commands
This section describes the commands you use to configure Internet Group Management Protocol
(IGMP) Snooping on the D-Link DES-3226L switch. The IGMP Snooping feature can help conserve
bandwidth because it allows the switch to forward IP multicast traffic only to connected hosts that
request multicast traffic.
set igmp
This command enables IGMP Snooping on the system (Global Config Mode) or an interface (Interface
Config Mode). This command also enables IGMP snooping on a particular VLAN and on all interfaces
participating in this VLAN.
If an interface has IGMP Snooping enabled and you enlist it as a member of a port-channel (LAG),
IGMP Snooping functionality is disabled on that interface. IGMP Snooping functionality is re-enabled
if you remove port-channel (LAG) membership from an interface that has IGMP Snooping enabled.
The IGMP application supports the following activities:
z Validation of the IP header checksum (as well as the IGMP header checksum) and discarding of the
frame upon checksum error.
z Maintenance of the forwarding table entries based on the MAC address versus the IP address.
z Flooding of unregistered multicast data packets to all ports in the VLAN.
