11.8.1.3 V_AGETIME – VLAN to Port aging time
CPU Address h402
Accessed by CPU (R/W)
Bit [7:0] - 2msec/unit. (Default FF)

CPU Address:h403

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 speedup aging when MCT resource is low.
0 – Enable speedup 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
