Casual Articles - Cisco CCNP Certification / BCMSN Exam Tutorial: Uplinkfast
Health, beyond any doubt, is one of the most important issues we face. Taking care of health is not just about curing various diseases, or even preventing various maladies that might have had an adverse effect on the general health of the people. It is also the whole and overall planning that makes various developmental models and strategic implementations for health coverage.These group health plans are not carrie
Uplinkfast is configured globally. You can't run Uplinkfast on some ports or on a per-VLAN basis - it's all or nothing.
The original root port will become the root port again when it detects that its link to the root switch has come back up. This does not take place immediately. The switch uses the following formula to determine how long to wait before transitioning back to the forwarding
In today’s technological era, you can’t afford not to have a presence in cyberspace as there are an ever-increasing number of people referring to the web as their major source of their information and research.Without doubt, your website represents a great opportunity to promote your properties for sale or to rent, in addition to your business generally, to the whole wide world.This is a real “no brainer” -
A switch can be connected to two other switches, giving that local switch a redundant path to the root bridge, and that's great - we always want a backup plan! However, STP will only allow one path to be available, but if the available path to the root switch goes down, there will be a 50-second delay due to the STP timers MaxAge and ForwardDelay before the currently blocked path will be available.
The delay is there to prevent switching loops, and we can't use PortFast to shorten the delay since these are switches, not host devices. What we can use is Uplinkfast.
The ports that SW3 could potentially use to reach the root switch are collectively referred to as an uplink group. The uplink group includes the ports in forwarding and blocking mode. If the forwarding port in the uplink group sees that the link has gone down, another port in the uplink group will be transitioned from blocking to forwarding immediately. Uplinkfast is pretty much PortFast for wiring closets. (Cisco recommends that Uplinkfast not be used on switches in the distribution and core layers.)
Some additional details regarding Uplinkfast:
The actual transition from blocking to forwarding mode takes about three seconds.
Uplinkfast cannot be configured on a root switch.

If saving were easy, everybody would do it.Sadly, despite the wealth of this nation, Americans are some of the worst savers in the world. I think it comes from our attitude of "I have a right to enjoy life;" therefore, we spend more than we earn and take on consumer debt to enjoy the goods things in life. The end result of our conspicuous consumption is a negative savings rate for most Americans, resulting in the i

Why should you want to steal someone else's stock market lesson plans?First, let me tell you that a trading plan is only useful if you follow it. Following your plan will make you successful, yet many traders circumvent the stock market lesson plans that they have carefully created. They become emotional invested in a trade, to the point where they ignore all warning signs. Remember, when the market corrects itself

Forums can be a very effective learning tool. I suggest you look for the most popular forums in your niche and read and post regularly to them. This tactic will definitely give your marketing an edge. Most of the people posting in the forums are running a similar business to yours. They may not be direct competitors, but by having products related to your niche you it is quite likely that they are experiencing simi

My father was an auditor at a large global accounting firm, helping innovative biotech and high-tech companies go public, about as far from your neighborhood “tax guy” as possible. Yet, whenever he told people he was in the accounting profession, they would smile knowingly and say something like “You must hate April 15th” (which is the day US income taxes are due). After a few years of trying to explain what he really did

The original root port will become the root port again when it detects that its link to the root switch has come back up. This does not take place immediately. The switch uses the following formula to determine how long to wait before transitioning back to the forwarding state:
( 2 x FwdDelay) + 5 seconds
Uplinkfast will take immediate action to ensure that the switch upon which it is configured cannot become the root switch. First, the switch priority will be set to 49,152, which means that if all other switches are still at their default priority, they'd all have to go down before this switch can possibly become the root switch. Additionally, the STP Port Cost will be increased by 3000, making it highly unlikely that this switch will be used to reach the root switch by any downstream switches.
And you just know there's got to be at least one option with this command, right? Let's run IOS Help and see.
SW2(config)#spanning-tree uplinkfast ?
max-update-rate Rate at which station address updates are sent
When there is a direct link failure, dummy multicast frames are sent to the MAC destination 0100.0ccd.cdcd. The max-update-rate value determines how many of these frames will be sent in a 100-millisecond time period.
Mastering the details of UplinkFast, BackboneFast, BPDU Guard, and Loop Guard are vital to your success on the CCNP exams, and one or more of these features are in use on almost every network in the world. Learn these features for success in both the exam room and the real world!
