Configuring Class of Service
10-8 Configuring and Monitoring the Switch
To configure VLANs, proceed as follows:
1. Select the Device Control Menu from the Main Menu.
2. Select 802.1Q VLAN Static Table Configuration Menu.
3. In the VID and VLAN Name fields, enter an ID number (1-2048) and a symbolic alphanumeric
name (up to 8 characters) to identify the VLAN.
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 to this VLAN.
7. To configure other VLANs, select New and press ENTER.
10.12 CONFIGURING CLASS OF SERVICE
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
Appendix C .
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.
10.13 CONFIGURING IGMP
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
Appendix D .)
NOTE: Note that the default for all ingress ports is zero.
