When should I enable STP?

Hello

I have my network with 300 series switches. We work in mode layer 3 and all other switches are layer 2.

I don't have a redundant path between switches. Should I enable STP? or is not necessary?

Thank you very much.

Hey Ruy,

It is rare to STP cause problems. There are a few rare cases it will cause a problem but overall after active STP should not affect your network.

I would recommend double checking everything on your network before you disable STP. Just one missed cable and your whole network freezes in a broadcast storm.

  • When should I be connected to iCloud on my iPhone

    When should I be connected to iCloud on my iPhone

    All the time. in my opinion there is no need to disconnect. But that's just me. iCloud works in the background. synchronizes photos, bookmarks, passwords, etc. All data, which must be recovered, when for example you lose your phone.

    Do not turn off during the night, do not turn on flight mode use the mode night so, iCloud can do a full backup. The phone must be powered and needs active WiFi.

    Turning off iCloud will take you to the time of Nokia 3310.

    I would use the software OCR supplied with the printer during the formatting of the document to be scanned is simple and use the IRIS PRO when the formatting is more complex.  You should expect some distortion of the two programs well formatted.  Hope that helps.

  • Cannot connect when Filevault is enabled

    Has anyone else had the number where they turn off filevault encryption in recovery mode, or they can not connect?

    The question began a few weeks ago, when I started having to turn off the computer and reset the PRAM. It would take to get my built-in keyboard and the trackpad to function has the fast connection after coming out of sleep.

    This same last week the PRAM reset don't would not fix the problem and fortunately the restore mode password reset brought me to disable my filevault encryption. This allowed to connect and enter my office.

    I then went through a few checks of the terminal base to verify the disk errors or file permissions and it come clean.

    I turned then encryption on my HD, and the problem has returned to the login screen.

    I disabled since filevault until I understand what is happening.

    I have noticed that this problem could be related to my use of my MacID software which allows me to use my fingerprint to iPhone reader unlock my MacBook.

    I started using this software at roughly the same time that this problem started occurring. This problem has been noted in the past?

    If so, what are the best solutions to work?

    Same thing here... the question begins to appear a month ago. A case open at Apple... updated the software and even re - install everything from scratch, in the image of failure to factory then re - enable FileVault, the same thing happens again.

    An interesting thing is the keyboard responds in fact every 8 to 10 seconds at the login screen, and you have about half of a second window to enter your password. If you do it slowly and well, you should be able to enter your password and login.

    Bringing in mine at the store for additional troubleshooting.

  • Cannot use WLAN on Satellite P100 when encryption is enabled

    My new P100-240 connects to the internet via my router Belkin MIMO cable and wireless without problem if I enable WEP security. If I enable security either 64 or 128-bit, then while the router connects to the laptop I can't access the internet, using the repair option does not work either!

    So now when you use the wireless installation to use no security on my network, or else I am unable to browse the internet. It is not ideal because you never know who wish to give use a connection high speed free wireless!

    Hello

    I would update the driver only if I would notice some problems with my laptop.
    For example if the WiFi connection is not stable; I would update the driver for wireless network card

  • When should I remove a certification authority that sounds strangely like I would never use it?

    When I opened the Manager under Tools/Options/Advanced certificates, I found a long list of certificate authorities that looked very suspicious to me. For example, the first was an outfit under the name of "TÜRKTRUST" with names of Turkish language.

    Where did this come from?

    There are quite a few other "suspects" looking for names of CA.

    What happens if I delete them all?

    OK, listen to the developers of firefox: YOU determine which I trust? I'm sorry, but sometimes I don't trust companies. It's part of the reason why most of the people stepped over to Firefox. Moreover, if for each "secure" connection in the world of browsers continue making connection to a very limited number of "certificate authorities" as "Verisign" / eTrust' etc., then the CONNECTION may be safe, but the FACT that xxx.xxx IP number connects to (ensure) website www.trytokeepasecret.org is 'leaked '. (as an average user is not informed or even not aware that issuers of certificates are associated with each secure connection) And I think that actually... my privacyis has missed.

    Connect to a Web site is something between me and this Web site and this is MY directive weather or not, I trust this Web site certificate, and no business of a third "certificate issuer". Arbitrary list in Firefox, Firefox users should have their say in it. It's MY secure connection and not Firefox! I don't trust Türktrust, or the rest of the list! And the fact that the developers of Firefox are trying to push this (telling me who to trust) in my throat makes me hate Firefox.
    In fact for THIS reason issueI find Firefox itself turns into an organization that I have more confidence. Just look at this list! It is obvious that someone pays enough money (or influence blackmarket) can become a transmitter of certificate.

    The Firefox people @: I would like to be able to connect to ANY Web site that I like, comprende?

    At the SAME TIME Firefox will automatically CONNECT to each tag advertising and tracking on all Web sites! (Again violate my privacy!)

    The only reason why I always use Firefox is because of the "requestpolicy" addon, which is able to block connections to 3rd-party sites. (TRY IT!) Why? Most sites use google analytical these days, and google must be connected to almost all Web sites UNLESS you use the requestpolicy! It's really an incredible feat the amount of information they collect while the main audience realizing it.

  • When should I use the 23.98 timeline?

    First of all, sorry for the rather ignorant question. But now. I noticed that quite a few tutorials use a 23.98 timeline. I shoot in 1080 p with the new Panasonic AG-DV200. What is the advantage of a 23.98 timeline and if I where to use this timeline, what should I get in? And then, what would the parameters should I export in if final distribution is for the web? Currently I have film in 1080 p, change in 1080 p, and then export in 720 p. Although I found a model in FCP for export Vimeo and who really look great. Bottom line... I am very confused. Is there a simple guide that I can speak on what to shoot in, change into, then export? As I said, I apologize for my confusion. I should know this stuff now.

    Thank you very much.

    Tom

    Everyone was new to this thing of frame rate at a given time, welcome to the family.

    Frame rate is a creative decision and a technical necessity. It can also be a ridiculous assignment. If you know that you are releasing a project than a film House, turn in 23.98. But less frames per second indicates your shutter can be opened a little longer for some sweet butter blurry but this is not always desirable and a few cameras will use a conversion process to bake to look like 24 of 30 frames per second. You know your equipment. More images gives you the opportunity to throw some away, farther in the post. Or say that you know that your car breaks down and explosions will require ultra slow so you shoot at 60, 120 or 10,000 frames per second (with specialized equipment).

    But there are tons of other creative and technical factors and the buffs will be in line with the suggestions for you. Try a simple search of "when shooting 23.98?" and you will find links to dozens of sites explainer and forums.

    We never pull at 23.98, but we, for effect, added a filter of conversion of frame projection film for a group of people watching a film projected on a screen. Our corporate stuff is always distributed online and it is (almost) always 30 fps (or is it 29.97) but sometimes 60 (or is it 59.94?).

  • When should I and how can I reset my wireless network?

    If I have problems printing, why should I reset my network?

    Most of us are well aware of the miracles that can happen to a simple reboot when you encounter computer problems.  Often, the same is true of wireless networks.  Over time the connections can become "cluttered" for lack of a better word.  A reset network will create a clean connection among the devices on the network and can often solve problems.

    When

    Any time you experience problems printing with a wireless printer and:

    1. you have excluded material problems,
    2. the print queue is clear, and
    3. running the HP print and Scan Doctor did not help.

    then reset the network should be very high on your to-do list, especially if the printer worked very well recently and now it isn't.

    How

    1. Shut down your computer (not restart).  If the computer tries to run updates, let that happens and wait for those finish.  For Windows 8 computers, hold down the "Shift" key when you click on the button 'stop '.  If you do not do this, the computer will go into hibernation and not to a full stop.
    2. Unplug all cables from the printer, including the power cord at the back of the printer when the printer is still on.  Unplug the other end of the power cord.  If there is a power supply on the power cord, disconnect one end.
    3. Unplug the power cord from the router for 20 seconds and plug it back.
    4. When the lights are on on the router, re - turn on the computer.
    5. When the computer is started to the top and you can access the Internet, plug the power cord into the power supply (if any), plug it directly into a wall socket (not a surge protector or battery backup), then again in the printer.
    6. When the printer powers back up, send a print job to the printer and see what happens.

    Even if this does resolve the problem, you will have a better connection that will be good for troubleshooting more far.
