Chapter 16 Ethernet Port Configuration

The following table describes the fields in this screen.

Table 87 Ethernet Port Configuration: Queue Method

LABEL

DESCRIPTION

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.

SPQ

Select SPQ (Strict Priority Queuing) to service queues based on priority only.

 

When the highest priority queue empties, traffic on the next highest-priority queue

 

begins. The default queuing method is Strictly Priority.

 

Weighted Fair Scheduling is used to guarantee each queue's minimum

 

bandwidth based on their bandwidth portion (weight) (the number you configure

 

in the Weight field). Queues with larger weights get more guaranteed bandwidth

 

than queues with smaller weights.

 

 

WRR

Select WRR (Weighted Round Robin Scheduling) to service queues on a rotating

 

basis based on their queue weight (the number you select from the drop-down list

 

box for the corresponding queue). Queues with larger weights get more service

 

than queues with smaller weights.

 

 

Apply

Click Apply to save the changes.

 

 

16.10 Protocol VLAN

Protocol based VLANs allow you to group traffic into logical VLANs based on the protocol you specify. When an upstream frame is received on a port (configured for a protocol based VLAN), the switch checks if a tag is added already and its protocol. The untagged packets of the same protocol are then placed in the same protocol based VLAN. One advantage of using protocol based VLANs is that priority can be assigned to traffic of the same protocol.

Note: Protocol based VLAN applies to un-tagged packets and is applicable only when you use IEEE 802.1Q tagged VLAN.

To open the Protocol VLAN screen, right-click on the switch in the Device List Panel, and click Configuration > Ethernet Port > Protocol VLAN. Then select a device and the port(s) to which you want to apply this configuration.
