Network interfaces cards (NICs) on SecurePlatform are configured to auto-negotiate link speed and duplex settings with the device to which they are physically connected to. If a NIC interface is unable to auto-negotiate with the device, it is necessary to hard code the settings.
Solution:
In expert mode, use the 'ethtool' to hard code link speed and duplex settings of network interfacesNICs.
Note: Per the IEEE specification, gigabit speed cannot be forced. It can only be auto-negotiated.
Quick command syntax:
Example:
(Set SecureOn(tm) password. Argument to this option must be 6 bytes in ethernet MAC hex format (
(Set driver message level. Meanings differ per driver).
Full options of command:
Example:
OPTIONS
Allows changing some or all settings of the specified Ethernet device; options only apply if
Device Name
Sets speed in Mbps; ethtool with a single argument will show supported device speeds.
Sets full- or half-duplex mode.
Selects device port.
Specifies whether or not autonegotiation is enabled.
Physical address
Selects transceiver type; currently only internal and external can be specified.
Sets Wake-on-LAN options; not all devices support this. The Argument to this option is a string of characters specifying the options to enable.
Note: Per the IEEE specification, gigabit speed cannot be forced. It can only be auto-negotiated.
Quick command syntax:
ethtool -s DEVNAME speed 10|100|1000 duplex full|half autoneg off|onExample:
ethtool -s eth0 speed 100 duplex full autoneg off
(Will force eth0 interface to 100 MB link speed, full duplex).ethtool -s eth0 speed 100 duplex half
(Will force eth0 interface to 100 MB link speed, half duplex).ethtool -s eth0 autoneg on
(Will force eth0 interface to auto-negotiate).ethtool -s eth0 autoneg off
(Will force eth0 interface auto-negotiate off).
