Data Sheet

Zarlink Semiconductor Inc.
Bit [0]:
Filter untagged frame
0: Disable (Default)
1: All untagged frames from this port are discarded or follow security option when
security is enable
Bit [1]:
Filter Tag frame
0: Disable (Default)
1: All tagged frames from this port are discarded or follow security option when
security is enable
Bit [2]:
Learning Disable
0: Learning is enabled on this port (Default)
1: Learning is disabled on this port
Bit [3]:
Must be ‘1’
Bit [5:4]
QOS mode selection. Determines which of the 4 sets of QoS settings is used for
10/100 ports.
00: select class byte limit set 0 and classes WFQ credit set 0 (Default)
01: select class byte limit set 1 and classes WFQ credit set 1
10: select class byte limit set 2 and classes WFQ credit set 2
11: select class byte limit set 3 and classes WFQ credit set 3
Note that there are 4 sets of per-queue byte thresholds, and 4 sets of WFQ ratios
programmed. These bits select among the 4 choices for each 10/100 port. Refer
to Programming QOS Registers Application Note, ZLAN-05.
Bit[7:6]
Security Enable. The ZL50418 checks the incoming data for one of the following
conditions:
If the source MAC address of the incoming packet is in the MAC table and is
defined as secure address but the ingress port is not the same as the port
associated with the MAC address in the MAC table.
A MAC address is defined as secure when its entry at MAC table has
static status and bit 0 is set to 1. MAC address bit 0 (the first bit
transmitted) indicates whether the address is unicast or multicast. As
source addresses are always unicast bit 0 is not used (always 0).
ZL50418 uses this bit to define secure MAC addresses.
If the port is set as learning disable and the source MAC address of the
incoming packet is not defined in the MAC address table or the MAC
address is not associated to the ingress port.
If the port is configured to filter untagged frames and an untagged frame
arrives
If the port is configured to filter tagged frames and a tagged frame arrives
If any one of the conditions is met, the packet is forwarded based on these setting.
00 – Disable port security, forward packets as usual. (Default)
01 – Discard violating packets
10 – Forward violating packets as usual and also to the CPU for inspection
11 – Forward violating packets to the CPU for inspection
