DESCRIPTION

VLAN Type

Choose 802.1Q or Port Based from the drop-down list box. The VLAN

 

Setup screen changes depending on whether you choose 802.1Q or Port

 

Based VLAN type in this screen. See Section 16.3 on page 165 and the

 

VLAN chapter for more information on VLANs.

 

 

MAC Address Aging Time

MAC address learning reduces outgoing traffic broadcasts. For MAC

 

address learning to occur on a port, the port must be active.

 

Enter a time from 10 to 3000 seconds. This is how long all dynamically

 

learned MAC addresses remain in the MAC address table before they age

 

out (and must be relearned).

 

 

Queuing Method

Select a queuing method. Choices vary depending on your switch

 

models.

 

Strict Priority Queuing (SPQ) services 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.

 

Weighted Round Robin Scheduling (WRR) services 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.

 

 

FE Port SPQ Enable

This field is applicable only when you select WFQ or WRR.

 

Select a queue (Q0 to Q7) to have the switch use Strictly Priority to

 

service the subsequent queue(s) after and including the specified queue

 

for the 10/100 Mbps Ethernet ports. For example, if you select Q5, the

 

switch services traffic on Q5, Q6 and Q7 using Strictly Priority.

 

Select None to always use WFQ or WRR for the 10/100 Mbps Ethernet

 

ports.

 

 

Q0-Q3

These fields are applicable only for switches that use WRR and for

 

switches that assign queue weights for the entire system (not per port).

 

Use the drop down list boxes to choose queue weights (1-15). Bandwidth

 

is divided across the different traffic queues according to their weights.

 

 

Broadcast Storm Control

These fields are not available on all switch models.

 

Set the fields below to configure traffic storm control.

 

 

Active

Select Active to enable traffic storm control on the switch.

 

 

Storm Control Type

Specify the traffic type in this field. Select Broadcast Only, Broadcast

 

and multicast, Broadcast and unknown unicast or Broadcast,

 

multicast and unknown unicast from the drop-down list box.

 

 

Packet Limit

From the drop-down list box, select the number of packets (of the type

 

chosen above) a port can receive per second.

 

 

Active Control

 

 

 

Link Aggregation

Select the check box to activate link aggregation.

 

 

Bandwidth control

Select the check box to activate bandwidth control.

 

 

Mirroring

Select the check box to activate port mirroring.

 

 

802.1x

Select the check box to activate IEEE 802.1x authentication.

 

 

Port Security

Select the check box to activate port security.
