14.4.3 GGControl – Extra GIGA Port Control
CPU Address:h036
Accessed by CPU and serial interface (R/W)
Bit[7:6]
Security Enable
(Default 00).
The MVTX2604 checks the incoming data for
one of the following conditions:
1. 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) indi-
cates whether the address is unicast or multicast. As source addresses are
always unicast bit 0 is not used (always 0). MVTX2600 uses this bit to
define secure MAC addresses.
2. 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.
3. If the port is configured to filter untagged frames and an untagged frame
arrives or if the port is configured to filter tagged frames and a tagged frame
arrives.
If one of these three conditions occurs the packet will be handled according
to one of the following specified options:
CPU installed
00 – Disable port security
01 – Discard violating packets
10 – Send packet to CPU and destination port
11 – Send packet to CPU only

Bit [0]:
Reset GIGA port A
0: Normal operation
(default)
1: Reset Gigabit port A. Normally used when a new Phy is connected (Hot swap).
Bit [1]:
GIGA port A use MII interface (10/100M)
0: Gigabit port operations at 1000 mode
(default)
1: Gigabit port operations at 10/100 mode
Bit [2]:
Device information insertion enable for Gigabit port A
0: Disable preamble stack device ID insertion
(default).
1: Insert stack device ID into the preamble (must be enabled for ring mode).
Bit [3]:
GIGA port A direct flow control (MAC to MAC connection). The MVTX2604
supports direct flow control mechanism; the flow control frame is therefore
not sent through the Gigabit port data path.
0: Direct flow control disabled
(default)
1: Direct flow control enabled
