SF 300

Friend of Delmas

I knocked in certain configuration of my network.  I have two switches sf300 and cisco router 827.  In fact sf300 supports dhcp server.  I took cisco 827 as dhcp server and I create 4 pools dhcp in it.

How do I configure in sf300 to service dhcp of the router cisco 827.  ISIT possible to configure 827 with interface bvi, when I try, I got error below.  Can someone help me configure the bvi interface and I'll link this bvi to vlan on sf300.

error in 827 router

Router (config-subif) #bridge - Group 1

The bypass on a subinterface LAN requires that the interface already
configured encapsulation Inter Switch Link (ISL) or 802. 1 q encapsulation

SF300 Configuration:

Int vlan 1

IP 192.168.1.1 255.255.255.0

int vlan 2

IP 192.168.2.1 255.255.255.0

int vlan 3

address 192.168.3.1 IP 255.255.255.0

int vlan 4

192.168.4.1 IP address 255.255.255.0

How can I connect two switch sf300 for redundancy?  I connected giga4 SW1 and SW2 giga4 mode trunk isit good or in any other way, I need to connect. ?

Thanks in advance.

Hi SIR,

You must have the correctly configured DHCP relay

Configure the terminal

activate a dhcp IP Relay

IP address of relay dhcp (DHCP server address)

Info IP dhcp (option 82) option

interface IG4

activate a dhcp IP Relay

The rest of your config seems fine for the switch.

    Mike,

    No, macOS Sierra is not compatible with your hardware.

    Here is an analytical compatibility.

  • kernel_task runaway (from 300 to 600%) CPU with 2 external displays

    I have a MacBook Pro (retina, mid-2012), and for a year and a half, I've had episodes fighter during the kernel_task suddenly begin to consume all processor CPU (from 300 to 600%), is the response of the system so slow it is impossible to use.  I experience these episodes throughout the front 1-2 years that the machine went from Yosemite El Capitan and now Sierra.

    Normally, I use my MacBook with two external displays, both at work and at home.  At work, I have two external screens of Lenovo, and at home, I have two screens Apple (Apple Cinema Display 27-inch and 27-inch Apple Thunderbolt Display). I discovered that this kernel_task high CPU usage can only be stopped by disconnecting one of the external screens.  After unplugging an external display, the kernel_task subsides immediately to normal (< 5%).  After a few minutes, I can reconnect the 2nd external screen and proceed normally (sometimes for days, sometimes for hours, sometimes for a few minutes) until the kernel_task pulls up to 300-600% again.  The use of the high CPU kernel_task never happens unless I have two external displays connected.

    Note that since I upgraded to MacOS Sierra fugue kernel_task CPU frequency has increased considerably: of 1 kernel_task runaway every several days to a runaway almost every 10 minutes or so.   I don't have a reason this frequency has increased, but the runaway condition seems to have worsened by the fact that the photoanalysisd daemon is running like crazy on my grand (72 000) library of Photos.

    Also note that I started in recovery mode and have re-installed MacOS Sierra, and it has no effect on the runaway kernel_task.

    Any ideas on how to fix this resumption of kernel_task of all my CPU?

    I have attached my EtreCheck system report below.  This report was captured with two attached external displays.  At halfway while generating a report, the kicks and started kernel_task hogging CPU again.

    Problem: Computer is too slow

    Description:

    Sometimes, while working with my MacBook connected to two external displays, the kernel_task pulls up to 600 to 800% CPU and stays there until I unplug at least one of the external screens.  After disconnecting, the kernal_task subsides immediately to normal (< 5%).  After a few minutes, I can plug the 2nd external screen and proceed normally (sometimes for days, sometimes for hours, sometimes for a few minutes) until the kernel_task pulls up to 600 to 800% again.  The use of the high CPU kernel_task never happens unless I have two external displays connected.

  • How to prevent the creation of 15000 files for 300 MB each day Firefox

    Firefox creates files of 'file' in C:\Users\LeRicain\AppData\Local\Mozilla\Firefox\Profiles\dnm04rk5.default\cache2
    There are about 10,000 and 20,000 files I have to remove to get about 300 MB of space each day

    How to prevent the creation of these files in Firefox

    Here are the files from cache. Basically, it takes Web sites that access you a lot and records bits of them so they'll load faster the next time you visit them. FOR EXAMPLE if you visit Google.com much, Firefox will save some elements of this page in the cache so that the next time visit you Google.com, it will not have to re - download.

Is there a way to fix this so the area that happens to 2.5 ghz is at least as fast as it was before the upgrade?  Sharon

    It is difficult to know the problem without knowing the full configuration.

    What modem router TWC has provided for you?

    Is the extreme connected by ethernet and you factory reset it after the change... Is it important?

    Extreme is bridged or Setup as a router?

    If the TWC router is wireless you need manual set channels. So go the TWC and set the channel Wireless 2.4 ghz to 1 and on the channel to 11 extreme game.

    The only difference would be if you want to watch the movie several times. In this case, download the movie first, would be more effective in terms of use of the data.
