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.
Use the ProSAFE Plus Utility to Customize IGMP Snooping
By default, IGMP snooping is enabled. You can customize the settings for your network.
To customize IGMP snooping:

Set Up Link Aggregation Groups
Link aggregation groups (LAGs) allow you to combine multiple Ethernet links to a single 
logical link. Network devices treat the aggregation as if it were a single link, which 
increases fault tolerance and load sharing. Configure LAG membership before you 
enable the LAG.
Note:LAGs are supported in switch model GSS116E, but they are not 
supported in switch model GSS108E.
Use the ProSAFE Utility to Enable LAGs
You must set up LAG membership before you enable LAG.s

Quality of Service
This chapter covers the following topics: 
•Enable 802.1p-Based Quality of Service
•Enable Port-Based Quality of Service
•Set Up Rate Limiting
•Set Up Broadcast Filtering

Enable 802.1p-Based Quality of Service
802.1p-based priority uses a header in the data packet that identifies t\
he class of data in the 
packet (for example, voice or video). When 802.1p-based priority is us\
ed, the switch reads 
information in the packet header to determine the priority to assign to \
the packet. All ports on 
the switch check the packet header and transmit the packet with a priori\
ty determined by the 
packet content.
Use the ProSAFE Utility to Enable 802.1p-Based QoS
To enable 802.1p-based QoS:
1. 
Connect your computer to the same network as the switch.
You can use a WiFi or wired connection.
2.  Double-click the  ProSAFE Plus Utility icon.
The configuration home screen displays a list of Plus switches that it d\
iscovers on the  local network.

7. Select the  Enable radio button.
A message displays warning you that previous QoS settings for the switch\
 will be lost.
8.  Click the  Ye
