16.9 IP Multicast
Use the IP Multicast screen to specify which multicast VLAN ID you want the device to
remove from the packets before transmitting.
1 In the Device Panel list, select a device and then right-click.
2 Click Configuration > Ethernet Port Configuration > IP Multicast.
3 Select a device and the port(s) to which you want to apply this configuration.
4 In the IP Multicast Egress Untag VLAN ID field, enter the multicast VLAN ID you
want to remove from the outgoing traffic.

16.10 DiffServ
DiffServ is a class of service (CoS) model that marks packets so that they receive specific per-
hop treatment at DiffServ-compliant network devices along the route based on the application
types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the
level of service desired. This allows the intermediary DiffServ-compliant network devices to
handle the packets differently depending on the code points without the need to negotiate paths
or remember state information for every flow. In addition, applications do not have to request
a particular service or give advanced notice of where the traffic is going.
Enable DiffServ in the DiffServ screen.
1 In the Device Panel list, select a device and then right-click.
2 Click Configuration > Ethernet Port Configuration > DiffServ.
Q0 - Q7 For Weighted Fair Scheduling, select the queue weight here. Bandwidth is divided across
the different traffic queues according to their weights. Queues with larger weights get more
guaranteed bandwidth than queues with smaller weights.
For Gigabit/ Mini-GBIC ports, if you select 0 for the queue weight, the switch uses Strictly
Priority to service the queue.
Apply Click Apply to save the changes.
