13.5.5 SCAN – SCAN Control Register (default 00)
CPU Address h404
Accessed by CPU (R/W)
Bit [0]:
1 – Enable fast learning mode. In this mode, the hardware learns all
the new MAC addresses at highest rate, and reports to the CPU while
the hardware scans the MAC database. When the CPU report queue is
full, the MAC address is learned and marked as “Not reported”. When
the hardware scans the database and finds a MAC address marked as
“Not Reported” it tries to report it to the CPU. The scan rate must be
set. SCAN Control register sets the scan rate.
(Default 0)
0 – Search Engine learns a new MAC address and sends a message
to the CPU report queue. If queue is full, the learning is temporarily
halted.
Bit [1]:
1 – Disable report new VLAN port association (Default 0)
0 – Report new VLAN port association
Bit [2]:
Report control
1 – Disable report MAC address deletion (Default 0)
0 – Report MAC address deletion (MAC address is deleted from MCT
after aging time)
Bit [3]:
Delete Control
1 – Disable aging logic from removing MAC during aging (Default 0)
0 – MAC address entry is removed when it is old enough to be aged.
However, a report is still sent to the CPU in both cases, when bit[2] = 0
Bit [4]:
1 – Disable report aging VLAN port association (Default 0)
0 – Enable Report aging VLAN. VLAN is not removed by hardware.
The CPU needs to remove the VLAN –port association.
Bit [5]:
1 - Report ARP packet to CPU (Default 0)
Bit [6]:
Disable MCT speedup aging (Default 0)
1 – Disable speed-up aging when MCT resource is low.
0 – Enable speed-up aging when MCT resource is low.
Bit [7]:
Slow Learning (Default 0)
1– Enable slow learning. Learning is temporary disabled when search
demand is high
0 – Learning is performed independent of search demand
