6.2.1 System Base Configuration Page
All the settings made in this page will take effect in the system of the Switch.
6.2.2 Packet drop if
There are two packet drop conditions, one is when packet encounters 16-time
collisions and the other is packet timeout.
Having the check mark on each box will enable corresponding packet drop
condition.
item description
Continuous
16-time
collision
If you enable this check mark, the same packet that
runs into 16 consecutive collisions will be dropped.
Timeout
If you enable this check mark, packet will be
dropped when the packet being queued over 1
second
The IEEE standard specifies the packet drop if it runs into 16 consecutive
collisions. For some performance reason, you can disable the function by
unmark
Continuous 16-time collision
item, and the Switch will retransmit the
packet after 16 consecutive collisions.
Default:
setting
Continuous 16-time collisions
.
6.2.3 Backoff operation mode
Set the switch backoff operation mode. Standard mode or SuperMAC mode.
Note:
SuperMAC means when collision occurrs, the Switch will reduce the
random waiting time to retransmit the packet.
Default:
setting
Standard mode
.
6.2.4 Address table mapping
Tell the switch how to map MAC address to its address table.
You can use CRC calculation to get the hashing index of address table direct
mapping to enable the whole address table mapping.
Note:
48-bit DA/SA address is translated separatly into 12-bit entry pointer of
address table for address learning and recognition. The translation is by aid of
CRC generator within the switch controller. The index of entry pointer selection
