Solution #00005096

 
Scope:
This solution replies to:
- NG Firewall firmware versions 4.2.x
- netfence firmware versions 4.2.x

 
Symptoms:

Some switches require setting the link speed of a network adapter manually, whitout autonegotiation. 


 

Solution:
This is possible via "Config" > "Box" > "Network" > "Inerfaces" > "Physical Interfaces" or directly in the interface setting via  "Config" > "Box" > "Network" > "Inerfaces" > "Network Interface Cards" as a driver module option.
 
To set the link speed of a network card manually you have to enter the driver options of the respective network card driver.

 

Driver Options:


Auto Negotation:

auto_speed=0 (Auto Negotation off)
auto_speed=1 (Auto Negotation on)

 

Line Speed:

line_speed=0 (Autonegotiate for highest speed supported) (default)
line_speed=10 (10 MBit/s)
line_speed=100 (100 MBit/s)
line_speed=1000 (1000 MBit/s)

 

Full Duplex:

full_duplex=0 (half-duplex)
full_duplex=1 (full-duplex)(default)

 

MTU:

mtu=xxx (xxx=size)

 

 

Examples:

To define the link speed of one interface to 100 MBit Full Duplex enter the following driver parameters:

auto_speed=0

line_speed=100

full_duplex=1

 

To define the link speed of one Broadcom interface to 100 MBit Half Duplex and the other Broadcom interface to 1000 MBit Full Duplex enter the following driver parameters:

auto_speed=0,0

line_speed=100,1000

full_duplex=0,1
