Description
1011 = 48 Mbps
1100 = 64 Mbps
1101 = 72 Mbps
1110 = 80 Mbps
1111 = 88 Mbps
Note: For 10Base-T, rate settings above 10Mbps are set to the default
value 0000 (Not limited).
Note: When multiple queue select enable is off (only 1 queue per port),
rate limiting applies only to priority 0 queue.
Description
Vct 10M short
Less than 10 meter short
Vct result
[00] = normal condition
[01] = open condition has been detected in cable
[10] = short condition has been detected in cable
[11] = cable diagnostic test is failed
Vct enable
1 = the cable diagnostic test is enabled. It’ll be self-
cleared after VCT test is done
0 = it indicates the cable diagnostic test is
completed and the status information is valid for
read
Force Link
1 = Force link pass
0 = Normal Operation
Power Saving
1 = Disable
0 = Enable power saving
Remote loop back
1 = Loop back at PMD/PMA of port 1’s PHY
0 = normal operation.
VCT fault count
Distance to the fault. The distance is approximately
0.4mXvct_fault_count
