Switch Settings
Figure7- 22. Switch Settings
Use the Switch Settings menu to change the following fields:
MAC Address Aging Time (sec):[300 ] *
This field specifies the length of time a learned MAC
Address will remain in the forwarding table without
being accessed (that is, how long a learned MAC
Address is allowed to remain idle). The Aging Time
can be set to any value between 10 and 1,000,000
seconds.
Switch 802.1x
This allows you to set 802.1x Port Based Network
Access for the whole Switch.
VDSL Rate Adaptive
This must be enabled if you use the Rate Adaptive
feature when you configure port settings.
Broadcast / Multicast Storm Mode
Select Enabled or Disabled to globally enable or
disable the Switch's reaction to Broadcast storms,
triggered at the threshold set below.
Limited Threshold for Ports
This is the number of Broadcast/Multicast packets in
Kbps received by the switch - on one of the base ports
- that will trigger the switch's reaction to a
Broadcast/Multicast storm.
*Note: A very long Aging Time can result with the out-of-date Dynamic Entries that may
cause incorrect packet filtering/forwarding decisions. A very short aging time may cause
entries to be aged out to soon, resulting in a high percentage of received packets
whose source addresses cannot be found in the address table.
