Table 64 Switch Configuration: Switch Setup
LABEL 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.
