Configure the Switch

Gigabit Ethernet Smart Managed Plus Click switches are plug-and-play , so they can be used without any configuration. Just connect power, connect to your network and to your other devices, and you’re done. You can also configure and manage additional advanced features of the switch either by using your computer’s web browser or by installing the ProSAFE Utility on your Windows-based computer.

Plus

For easiest access, we recommend that you cable the switch to a network with a router or DHCP server that assigns IP addresses, power on the switch, and then use a computer that is connected to the same network as the switch (on-network). However, it is also possible to configure the switch connected directly only to the computer that you are using to configure it, and not connected to the network (off-network).

You can configure and manage advanced features of the switch either by using your computer’s web browser and accessing the switch at its IP address or by installing the ProSAFE Plus Utility on your Windows-based computer.

Manage Multicast Traffic With IGMP Snooping

Internet Group Management Protocol (IGMP) snooping allows a switch to forward multicast traffic intelligently on the switch. Multicast IP traffic is traffic that is destined to a host group. Host groups are identified by Class D IP addresses, which range from 224.0.0.0 to

239.255.255.255. Based on the IGMP query and report messages, the switch forwards traffic only to the ports that request the multicast traffic. This feature prevents the switch from broadcasting the traffic to all ports and possibly affecting network performance.

The switch maintains a map that shows which links need which IP multicast streams. The switch forwards multicast traffic only to the links that requested them and cuts multicast traffic from links that do not contain a multicast listener. Essentially, IGMP snooping helps optimize multicast performance at Layer 2 and is especially useful for bandwidth-intensive IP multicast applications such as IPTV.

Customize IGMP Snooping

By default, IGMP snooping is enabled. You can customize the settings for your network.

 To customize IGMP snooping:

1. Connect your computer to the same network as the switch.

Set Up Link Aggregation Groups

Link aggregation groups (LAGs) allow you to combine multiple Ethernet links into a single logical link. Network devices treat the aggregation as if it were a single link, which increases fault tolerance and load sharing. Specify LAG membership before you enable the LAG. The switch supports up to two static LAGs.

 To specify LAG membership and enable one or both LAGs:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired network connection, or connect directly to a switch that is of

f-network using an Ethernet cable.

2. Launch a web browser.
