Data Sheet

Zarlink Semiconductor Inc.
5.3.3 Aging
Aging time is controlled by register 400h and 401h.
The aging module scans and ages MCT entries based on a programmable “age out” time interval. As we indicated
earlier, the search module updates the source MAC address and VLAN port association timestamps for each
frame it processes. When an entry is ready to be aged, the entry is removed from the table,and a “Delete MAC
Address” message is sent to inform the CPU.
Supported MAC entry types are: dynamic, static, source filter, destination filter, IP multicast, source and
destination filter and secure MAC address. Only dynamic entries can be aged; all others are static. The MAC entry
type is stored in the “status” field of the MCT data structure.
5.3.4 VLAN Table
The table below provides a mapping from VLAN ID to VLAN index. It is maintained by system software and is
checked by the hardware search engine for every incoming frame. This table has 4 K entries and is stored in
external SRAM. It is organized as 512
×
8 entries (total of 4 K VLAN indexes) as shown. Each VLAN index is 8
bits.
Each VIX represents the mapping result from the associated VLAN ID (VLANID = 0x004 is mapped to VIX4).
Unused VLAN ID’s have their corresponding VIX programmed to hexadecimal 00. Used VLAN ID’s have their
corresponding VIX programmed to hexadecimal 01 through FF. In other words, 255 VLAN’s are supported. The
VIX value is a pointer to the entries in the VLAN Index port association table (internal memory).
The VLAN Index port association table is used by both software and hardware. It contains 256 entries. Each
entry has 27 fields, such that each field represents the port status of that particular VLAN.
