Схемы электропитания

Отсутствие схем электропитания вероятнее всего связано с новым режимом питания на устройствах с аккумулятором в версии 1709 . Если щелкнуть значок батареи, то можно видеть слайдер, который появится только, если выбрана схема «Сбалансированная».

Схемы можно восстановить следующими способами: сделать схему «Высокая производительность» или «Экономия энергии» активной, при этом активная схема появится в Панели управления, или же создать дубликаты этих схем, и тогда появятся обе схемы. В Командной строке нужно выполнить команды.

 

Сделать схему активной: powercfg.exe /setactive <GUID схемы питания>

 

Создать дупликат схемы: powercfg -duplicatescheme <GUID схемы питания>

 

Вместо <GUID схемы питания> нужно вставить GUID соответствующей схемы.

 

Для схемы "Сбалансированная" - 381b4222-f694-41f0-9685-ff5bb260df2e

 

Для схемы "Экономия энергии" - a1841308-3541-4fab-bc81-f71556f20b4a

 

Для схемы "Высокая производительность" - 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c

ether1 = ISP1
ether2 = ISP2
ether3 = bridge

Step 0.

Macs if need

set [ find default-name=ether1 ] mac-address=x name=ISP1
set [ find default-name=ether2 ] mac-address=x name=ISP2

Step 1.
Add dynamic client on ether1 & ether2 (WAN1 & WAN2)

/ip dhcp-client
add add-default-route=no dhcp-options=hostname,clientid disabled=no interface=ISP1 use-peer-dns=no use-peer-ntp=no
add add-default-route=no dhcp-options=hostname,clientid disabled=no interface=ISP2 use-peer-dns=no use-peer-ntp=no

Step 2: Add Lan Interface IP . ( ether3 )

1
2
/ip address
add address=192.168.88.1/24 interface=ether3 network=192.168.88.0

Step 3: Add Firewall Nat rule.

/ip firewall nat
add action=masquerade chain=srcnat disabled=yes out-interface=ISP1
add action=masquerade chain=srcnat disabled=yes out-interface=ISP2

Step 4:  Add firewall Mangle Rules

/ip firewall mangle
add action=mark-connection chain=prerouting comment=ISP1 connection-state=new disabled=yes in-interface=ISP1 new-connection-mark=ISP1-conn passthrough=yes
add action=mark-routing chain=output comment=ISP1 connection-mark=ISP1-conn disabled=yes new-routing-mark=ISP1-route passthrough=yes
add action=mark-connection chain=prerouting comment=ISP2 connection-state=new disabled=yes in-interface=ISP2 new-connection-mark=ISP2-conn passthrough=yes
add action=mark-routing chain=output comment=ISP2 connection-mark=ISP2-conn disabled=yes new-routing-mark=ISP2-route passthrough=yes

add action=mark-connection chain=prerouting comment=ISP1 connection-state=new disabled=yes dst-address-type=!local in-interface=bridge new-connection-mark=ISP1-conn passthrough=yes per-connection-classifier=both-addresses:2/0
add action=mark-connection chain=prerouting comment=ISP2 connection-state=new disabled=yes dst-address-type=!local in-interface=bridge new-connection-mark=ISP2-conn passthrough=yes per-connection-classifier=both-addresses:2/1

add action=mark-routing chain=prerouting comment=ISP1 connection-mark=ISP1-conn disabled=yes in-interface=bridge new-routing-mark=ISP1-route passthrough=yes
add action=mark-routing chain=prerouting comment=ISP2 connection-mark=ISP2-conn disabled=yes in-interface=bridge new-routing-mark=ISP2-route passthrough=yes

add action=mark-connection chain=input disabled=yes in-interface=ISP1 new-connection-mark=ISP1-conn passthrough=yes
add action=mark-routing chain=output connection-mark=ISP1-conn disabled=yes new-routing-mark=ISP1-route passthrough=no
add action=mark-connection chain=input disabled=yes in-interface=ISP2 new-connection-mark=ISP2-conn passthrough=yes
add action=mark-routing chain=output connection-mark=ISP2-conn disabled=yes new-routing-mark=ISP2-route passthrough=no

add action=mark-connection chain=forward disabled=yes in-interface=ISP1 new-connection-mark=ISP1-conn-f passthrough=no
add action=mark-routing chain=prerouting connection-mark=ISP1-conn-f disabled=yes in-interface=bridge new-routing-mark=ISP1-route
add action=mark-connection chain=forward disabled=yes in-interface=ISP2 new-connection-mark=ISP2-conn-f passthrough=no
add action=mark-routing chain=prerouting connection-mark=ISP2-conn-f disabled=yes in-interface=bridge new-routing-mark=ISP2-route

Step 5: Add Routes ( Setting temporary  gateway)

/ip route
add check-gateway=ping comment="Ether1-Wan routing gateway" distance=1 gateway=192.168.0.1 routing-mark=ISP1-route
add check-gateway=ping comment="Ether2-Wan routing gateway" distance=1 gateway=192.168.1.1 routing-mark=ISP2-route
add comment=Ether1-Wan distance=1 gateway=192.168.0.1
add comment=Ether2-Wan distance=2 gateway=192.168.1.1

step 6: Create New Script with name change_gw and copy below lines.

:global newgw [/ip dhcp-client get [find interface="ISP1" ] gateway ]
:global activegw [/ip route get [/ip route find comment="Ether1-Wan"] gateway ]
:if ($newgw != $activegw) do={
/ip route set [find comment="Ether1-Wan"] gateway=$newgw
/ip route set [find comment="Ether1-Wan routing gateway"] gateway=$newgw
}
:global newgw [/ip dhcp-client get [find interface="ISP2" ] gateway ]
:global activegw [/ip route get [/ip route find comment="Ether2-Wan"] gateway ]
:if ($newgw != $activegw) do={
/ip route set [find comment="Ether2-Wan"] gateway=$newgw
/ip route set [find comment="Ether2-Wan routing gateway"] gateway=$newgw
}

Step 7: Final Step.

It is possible to go back to a more classic iptables setup. First, stop and mask the firewalld service:

systemctl stop firewalld
systemctl mask firewalld

Then, install the iptables-services package:

yum install iptables-services

Enable the service at boot-time:

systemctl enable iptables

Managing the service

systemctl [stop|start|restart] iptables

Saving your firewall rules can be done as follows:

service iptables save

or

/usr/libexec/iptables/iptables.init save

Performance Tuning Windows 2012: Network Subsystem Part 2

In our previous article we discussed the hardware supported features of some of the high-end network adapters. Let’s take a look how you can use some of those settings to their best advantage. Remember that the correct settings depend on the network adapter, your workload, the resources of the host computer, and of course your performance goals.
