Transition from link test pass to link test fail
18.2.2 Transmit data in progress
This signal indicates the port is transmitting data.
18.2.3 Receive data in progress
This signal indicates port receive activity.
18.2.4 Collision active
This signal indicates the port collision event detected by the port.
18.2.5 Full/Half duplex
This signal indicates the port duplex: active - full duplex, inactive - half duplex.
18.2.6 Receive Buffer Full
In order for this LED to be active, Rx Buffer Threshold must be enabled (see Table 4). This signal indicates the port
receive buffer status: active - the buffer exceeds it's programmed threshold, inactive otherwise.
18.2.7 Forwarding of unknown packets enabled
This signal indicates the port mode of forwarding unknown packets: active - forwarding unknown packets enabled,
inactive otherwise.
18.2.8 The port is configured as Sniffer
This signal indicates if the port mode is configured as a sniffer target port: active - port is a target sniffer, inactive othe r-
wise.
18.2.9 Link Fail State
This signal indicates the port link status: active - link is down, inactive - link is up.
18.2.10 Partition State
This signal indicates the port partition status: active - port entered partition state, inactive otherwise.
18.2.11 Secondary Port Status LED
Indicates the secondary status mode as per the inverted value of LEDMode input.
18.2.12 Pure Port Status LED
This signal will be inactive for any of the following events:
Port is disabled
Link Integrity Test Failed
Partition State Detected
Otherwise, this signal is active.
