4. Set the Status field to Active.

5. Under Egress Ports, select ports by entering “1,” or enter “0” to remove it from the VLAN.

6. Under Forbidden Egress Ports, enter a “1” to prevent a port from being part of this VLAN. 

7. To configure other VLANs, select New and press ENTER.

You can configure Class of Service parameters using the 802.1P Port Priority Configuration 
screen. This screen permits you to configure two priority levels for traffic being forwarded through 
the switch. During periods of congestion, Class of Service settings ensure that traffic which has 
been assigned high priority is forwarded through the switch ahead of normal priority traffic. For 
further information, refer to 

.

To configure Class of Service, proceed as follows:

1. Select Device Control Menu from the Main Menu.

2. Select 802.1P Configuration, then 802.1P Port Priority Configuration.

3. Set the individual port priorities by entering 0-3 for the low priority queue or 4-7 for the high 

priority queue.

This switch uses IGMP (Internet Group Management Protocol) to query for any attached hosts 
who want to receive a specific multicast service. The switch looks up the IP Multicast Group used 
for this service and adds any port which received a similar request to that group. It then propagates 
the service request on to any neighboring multicast switch/router to ensure that it will continue to 
receive the multicast service. (For information about the use of IGMP snooping and multicast 
filtering, refer to 

.)

To configure IGMP operation, proceed as follows:

1. Select Device Control Menu from the Main Menu.

2. Select IGMP Configuration and press ENTER.

3. Set the IGMP Status to ENABLED. This enables the switch to monitor network traffic to 

determine which hosts want to receive multicast traffic. Default is DISABLED.

NOTE: Note that the default for all ingress ports is zero.
