Switching
MAC address aging
Valid input: 1 to 16 666
Default value: 15 minutes
Function: The time that a MAC address is kept in the database before being purged if it
has not transmitted data. If you set MAC Address Aging time too low, the switch sends out
frames with unknown destinations (because the switch has purged the address and has not
re-learned it) on all ports - this is called flooding.
Comment: MAC address aging is overruled by changes in the Spanning Tree. The MAC address
database can contain up to 8000 entries for the entire switch. MAC addresses detected
after 8000 entries are discarded. If addresses connected to the port are defined as
permanent entries, they are not purged.
Default flow control
Valid input: Enable or Disable.
Default value: Enable.
Function: The default value specified here applies to all ports.
Default switch forwarding mode
Valid input: Adaptive, Cut-through, Fragment-free, Store-and-forward.
Default value: Adaptive.
Function: Determines the forwarding mode to be used by default for all the ports on the
switch.
Comment: The default value specified here applies to all ports unless they have been
individually configured.
Forward learn packets
Valid input: Enabled or disabled
Default value: Disabled
Function: Forwards only "IPX Get Server request" packets by default. To forward
other learn packets select this option.
Comment: If you enable this is feature it will produce an increase in traffic, but this
may be needed to speed up the 'learning' of new stations.
