Меняем скорость и дуплекс сетевой карты

FreeBSD

Что бы узнать какие режимы поддерживаются данной карточкой, используем такую команду:

# ifconfig -m nfe0
nfe0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=8210b<RXCSUM,TXCSUM,VLAN_MTU,TSO4,WOL_MAGIC,LINKSTATE>
        capabilities=8210b<RXCSUM,TXCSUM,VLAN_MTU,TSO4,WOL_MAGIC,LINKSTATE>
        ether fa:d5:5e:f7:db:ff
        inet 192.168.1.40 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::f8d5:5eff:fef7:dbff%nfe0 prefixlen 64 scopeid 0x4
        inet 192.168.0.11 netmask 0xffffff00 broadcast 192.168.0.255
        inet 10.11.11.2 netmask 0xffffff00 broadcast 10.11.11.255
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
        supported media:
                media autoselect mediaopt flowcontrol
                media autoselect
                media 100baseTX mediaopt full-duplex
                media 100baseTX
                media 10baseT/UTP mediaopt full-duplex
                media 10baseT/UTP

Установим нужное значение:

# ifconfig nfe0 media 10baseT/UTP mediaopt full-duplex

В /etc/rc.conf это будет выглядеть так:

ifconfig_nfe0="inet 192.168.0.1 netmask 255.255.255.0 media 10baseT/UTP mediaopt full-duplex"

OpenBSD

Всё тоже самое, за исключением определения поддерживаемых скоростей

# ifconfig rl0 media
rl0: flags=8843 mtu 1500
        lladdr 00:50:ba:c0:eb:60
        priority: 0
        media: Ethernet autoselect (100baseTX full-duplex)
        status: active
        supported media:
                media 10baseT
                media 10baseT mediaopt full-duplex
                media 100baseTX
                media 100baseTX mediaopt full-duplex
                media autoselect
        inet 10.25.1.46 netmask 0xfffffffc broadcast 10.25.1.47

Для постоянного закрепления в /etc/hostname.rl0 просто дописываем нужную скорость.

Linux

Встроенных средств для этого нет, зато есть сторонние утилиты ethtool, mii-diag(mii-tool). Вот как это выглядит:

# mii-tool -v eth0
eth0: no autonegotiation, 1000baseT-FD flow-control, link ok
product info: Yukon 88E1011 rev 4
basic mode: autonegotiation enabled
basic status: autonegotiation complete, link ok

link partner: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
#mii-tool -F 10baseT-FD eth0

# ethtool eth0
Settings for eth0:
        Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Advertised pause frame use: No
        Advertised auto-negotiation: Yes
        Speed: 1000Mb/s
        Duplex: Full

        PHYAD: 0
        Transceiver: internal
        Auto-negotiation: on
        MDI-X: Unknown

        Current message level: 0x00000007 (7)
        Link detected: yes
#ethtool -s eth0 speed 10 duplex full autoneg off

Ошибок не выдало, но скорость изменить не получилось (может проблема с сетевой). Если 2-м разным утилитам не удалось это сделать, значит дело скорее всего в сетевой карте.

Solaris 10

Узнаем поддерживаемые режимы:

# ndd /dev/hme \? | grep '(read and write)'
adv_autoneg_cap               (read and write)
adv_1000fdx_cap               (read and write)
adv_1000hdx_cap               (read and write)
adv_100fdx_cap                (read and write)
adv_100hdx_cap                (read and write)
adv_10fdx_cap                 (read and write)
adv_10hdx_cap                 (read and write)
tx_bcopy_threshold            (read and write)
tx_interrupt_enable           (read and write)
tx_intr_delay                 (read and write)
tx_intr_abs_delay             (read and write)
rx_bcopy_threshold            (read and write)
max_num_rcv_packets           (read and write)
rx_intr_delay                 (read and write)
rx_intr_abs_delay             (read and write)
intr_throttling_rate          (read and write)
intr_adaptive                 (read and write)

Если через ndd нельзя получить информацию:

#ndd -get /dev/bge ?
operation failed, Invalid argument

то можно получить информацию через kstat:

$ kstat -p | grep bge | grep adv_cap_10
bge:0:mac:adv_cap_1000fdx       1
bge:0:mac:adv_cap_1000hdx       1
bge:0:mac:adv_cap_100fdx        1
bge:0:mac:adv_cap_100hdx        1
bge:0:mac:adv_cap_10fdx 1
bge:0:mac:adv_cap_10hdx 1
bge:0:mii:adv_cap_1000fdx       1
bge:0:mii:adv_cap_1000hdx       1
bge:0:mii:adv_cap_100fdx        1
bge:0:mii:adv_cap_100hdx        1
bge:0:mii:adv_cap_10fdx 1
bge:0:mii:adv_cap_10hdx 1

Проверка:

ndd /dev/hme link_mode
0 = half duplex, 1 = full duplex

Установка full duplex:

ndd -sec /dev/hme adv_100fdx_cap
ndd -set /dev/hme adv_autoneg_cap 0

Установка half duplex:

ndd -sec /dev/hme adv_100hdx_cap
ndd -set /dev/hme adv_autoneg_cap 0

А вот ещё пример использования

# ndd /dev/bge0 link_duplex
2
# ndd /dev/bge0 link_autoneg
1
# ndd /dev/bge0 link_status
1
# ndd /dev/bge0 link_speed
1000

Установка

# ndd -set /dev/e1000g0 adv_autoneg_cap 0
# ndd -set /dev/e1000g0 adv_100fdx_cap 1

а так же установить 0 для всех остальных режимов:

# ndd -set /dev/e1000g0 adv_1000fdx_cap 0
# ndd -set /dev/e1000g0 adv_100hdx_cap 0
# ndd -set /dev/e1000g0 adv_10fdx_cap 0
# ndd -set /dev/e1000g0 adv_10hdx_cap 0

Для постоянного изменения, добавим такой код в /etc/system

set e1000g:adv_autoneg_cap=0
set e1000g:adv_100fdx_cap=1
set e1000g:adv_1000fdx_cap=0
set e1000g:adv_100hdx_cap=0
set e1000g:adv_10fdx_cap=0
set e1000g:adv_10hdx_cap=0

Новый вариант:

# dladm set-linkprop -p mtu=9706 net0
