Network 10Mb/s half duplex only. r8168 on Centos 5.
Hi,
For some reason my network card started going 10Mb/s half duplex instead of 1000Mb/s full duplex. System is connected to 8x1Gb HP switch.
Other devices connect fine through the switch and get full 1Gb network.
I have Centos 5 with all updates. Driver comes from elrepo and as well is updated.
Hi,
How to find whether the server is running with half duplex or full duplex. I tried with the following command ndd -get /dev/ but am not getting any output,. Is the command correct?
Also let me know how to change from half to full duplex. (1 Reply)

Hi all,
I need to add domain and search parameters to resolv.conf, however network manager overwrites.
Setting the PEERDNS=No in the interface file seems to have no effect on this behaviour.
Sadly I cannot just disable NM as these are not my hosts, I'm just attempting to install a platform... (3 Replies)

txp
TXP(4) BSD Kernel Interfaces Manual TXP(4)NAME
txp -- 3Com 3XP Typhoon/Sidewinder (3CR990) Ethernet interface
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device txp
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_txp_load="YES"
DESCRIPTION
The txp interface provides access to the 10Mb/s and 100Mb/s Ethernet networks via the 3Com Typhoon/Sidewinder chipset.
Basic Ethernet functions are provided as well as support for vlan(4) tag removal and insertion assistance, receive ip(4), tcp(4), and udp(4)
checksum offloading, and transmit ip(4) checksum offloading. There is currently no support for transmit tcp(4) or udp(4) checksum offload-
ing, tcp(4) segmentation, nor ipsec(4) acceleration.
When a txp interface is brought up, by default, it will attempt to auto-negotiate the link speed and duplex mode. The speeds, in order of
attempt, are: 100Mb/s Full Duplex, 100Mb/s Half Duplex, 10 Mb/s Full Duplex, and 10 Mb/s Half Duplex.
The txp supports several media types, which are selected via the ifconfig(8) command. The supported media types are:
media autoselect
Attempt to autoselect the media type (default)
media 100baseTX mediaopt full-duplex
Use 100baseTX, full duplex
media 100baseTX [mediaopt half-duplex]
Use 100baseTX, half duplex
media 10baseT mediaopt full-duplex
Use 10baseT, full duplex
media 10baseT [mediaopt half-duplex]
Use 10baseT, half duplex
HARDWARE
The txp driver supports the following cards:
o 3Com 3CR990-TX-95
o 3Com 3CR990-TX-97
o 3Com 3cR990B-TXM
o 3Com 3CR990SVR95
o 3Com 3CR990SVR97
o 3Com 3cR990B-SRV
SEE ALSO altq(4), arp(4), inet(4), intro(4), ip(4), miibus(4), tcp(4), udp(4), vlan(4), ifconfig(8)HISTORY
The txp driver first appeared in OpenBSD 2.9.
