There are three steps to configuring Class-Based Weighted Fair Queuing (CBWFQ) on a router. First, you have to create one or more class maps that describe the traffic types. Then you create a policy map that tells the router what to do with these traffic types. Finally, you need to attach this policy map to one or more of the router's interfaces:
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#class-map highprec
Router(config-cmap)#description Highest priority Prec=5

CBWFQ need not be significantly different from regular WFQ. In the example we have defined all traffic with an IP Precedence value of critical (5) to have a special queue. We have also created a single queue for traffic with Precedence 4, and another one for traffic with Precedence values of 2 and 3. All other traffic, including traffic with Precedence 0 and 1, as well as all nonIP traffic uses regular WFQ. To make this fact slightly more clear, we have modified the default WFQ parameters with the following commands:
Router(config)#policy-map cbwfqpolicy
Router(config-pmap)#class class-default
Router(config-pmap-c)#fair-queue 512
Router(config-pmap-c)#queue-limit 96
This simply modifies the default WFQ behavior for all traffic that doesn't match one of the other defined classes. It sets the number of WFQ queues to 512, and sets the queue depth to a maximum of 96 packets.
Router(config-if)#fair-queue 96 512 0
But that example doesn't give you the ability to also have separate queues for special classes of traffic, as shown in this recipe. We note in passing that the final argument for this fair-queue interface command specifies the number of queues to set aside for RSVP. We are trying to duplicate the effect of the cbwfqpolicy policy map, which doesn't include any RSVP queues, so we have set the last argument to zero here.
You can create up to 64 Class-based queues for use with CBWFQ. You can control the share of the bandwidth to each queue using the bandwidth keyword either by using an absolute value in kilobits per second, or a percentage of the total available bandwidth. The following example shows the syntax for using a percentage:
Router(config-pmap)#class highprec
Router(config-pmap-c)#bandwidth percent 25
Router(config-pmap-c)#exit
The bandwidth percent command is available in IOS levels 12.1(1) and higher. For earlier releases, you can only specify an absolute bandwidth:
Router(config-pmap-c)#bandwidth 5000
The argument for this version of the command is a value in kilobits per second between 8 and 2,000,000, which should be sufficient for most interface types. Note that the upper limit here is 2 Mbps, which is roughly the E1 speed mentioned earlier as the effective upper limit to using WFQ. Because CBWFQ generally uses fewer queues and doesn't need to sort based on flow, you can use it for higher speed interfaces as well. However, you should let your average CPU utilization be your guide here. If you do too many tests when classifying packets, you might find that the router can't keep up with high packet rates.
In both versions, you have to keep two important factors in mind. First, although this is essentially a Layer 3 feature, when configuring the bandwidth you have to include any Layer 2 framing overhead. If a given queue supports a streaming multimedia application with a known bit rate, it is often a good idea to slightly overestimate the requirements to include this Layer 2 overhead. If the application doesn't use the excess, CBWFQ allocates it to other queues.
The second important factor is that the total allocated bandwidth must not exceed a configurable maximum value. By default, this maximum is 75 percent. You can change it, for example, to 80 percent by using the following interface level command:
Router(config-if)#max-reserved-bandwidth 80
You would apply this command to the interface that runs CBWFQ and needs a little extra reserved capacity. It is usually best to leave this at its default value, however. The router uses the remainder for unclassified traffic and network control packets. In this case, we have configured WFQ for the unclassified traffic. It is vital, however, to reserve enough bandwidth for critical network functions such as Layer 2 keepalive frames and routing protocols.
Creating the policy map alone doesn't actually change the way the router behaves. To do that, you have to attach this policy to an interface as follows:
Router(config)#interface serial0/1
Router(config-if)#service-policy output cbwfqpolicy
One of the classes defined in this example is a high-priority class that we called highpriority. This class map simply looks for traffic that is tagged with an IP precedence value of 5. The policy map then tells the interface to give up to 25 percent of its bandwidth to this high priority traffic. If there is not enough high-priority traffic to use this, the router will allocate the excess to the remaining traffic.

If there is not enough high-priority traffic to use this, the router will allocate the excess to the remaining traffic.

The solution to this difficulty is dependent upon the sort of potential customers distinctions you are looking for to create, at the same time the model of IOS you may be managing inside of your routers.

There ought to be a little something that defines the various types of potential customers you want to prioritize. In most cases, the simpler the distinctions are to produce, the higher. It's because each of the checks take router sources and introduce processing delays. The commonest rules for distinguishing in between potential customers types utilize the packet's input interface and basic IP header detail this sort of as TCP port figures. The following examples display the way to set an IP Precedence value of instantaneous (two) for all FTP command traffic that arrives because of the serial0/0 interface, and an IP Precedence of concern (1) for all FTP data targeted traffic. This distinction is possible as FTP regulate visitors uses TCP port 21, and FTP information uses port 20.

The newest process for configuring this uses class maps. Cisco 1st launched this feature in IOS Version twelve.0(five)T. This method first defines a class-map that specifies how the router will discover this type of site traffic. It then defines a policy-map that truly makes the modifications for the packet's TOS industry:

Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#access-list 101 permit any eq ftp any
Router(config)#access-list 101 permit any any eq ftp
Router(config)#access-list 102 permit any eq ftp-data any
Router(config)#access-list 102 permit any any eq ftp-data
Router(config)#class-map match-all ser00-ftpcontrol
Router(config-cmap)#description branch ftp control traffic
Router(config-cmap)#match input-interface serial0/0
Router(config-cmap)#match access-group 101
Router(config-cmap)#exit
Router(config)#class-map match-all ser00-ftpdata
Router(config-cmap)#description branch ftp data traffic
Router(config-cmap)#match input-interface serial0/0
Router(config-cmap)#match access-group 102
Router(config-cmap)#exit
Router(config)#policy-map serialftppolicy
Router(config-pmap)#description branch ftp traffic policy
Router(config-pmap)#class ser00-ftpcontrol
Router(config-pmap-c)#set ip precedence immediate
Router(config-pmap-c)#exit
Router(config-pmap)#class ser00-ftpdata
Router(config-pmap-c)#set ip precedence priority
Router(config-pmap-c)#exit
Router(config-pmap)#exit
Router(config)#interface serial0/0
Router(config-if)#ip route-cache policy
Router(config-if)#service-policy input serialftppolicy
Router(config-if)#exit
Router(config)#end
Router#

For before IOS variations, where by class-maps ended up not offered, you have to implement policy-based routing to change the TOS subject in a packet. Making use of this coverage into the interface tells the router to make use of this coverage to check all incoming packets on this interface and rewrite those that match the route map:Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#access-list 101 permit any eq ftp any
Router(config)#access-list 101 permit any any eq ftp
Router(config)#access-list 102 permit any eq ftp-data any
Router(config)#access-list 102 permit any any eq ftp-data
Router(config)#route-map serialftp-rtmap permit 10

Router(config)#route-map serialftp-rtmap permit 20
Router(config-route-map)#match ip address 102
Router(config-route-map)#set ip precedence priority
Router(config-route-map)#exit
Router(config)#interface serial0/0
Router(config-if)#ip policy route-map serialftp-rtmap
Router(config-if)#ip route-cache policy

Earlier than you?ˉre able to tag a packet for distinctive therapy, you will have to have a particularly obvious concept of what forms of page views really want exclusive treatment method, not to mention precisely what sort of exclusive treatment method they may will want. From the illustration, we've chose to give a specific priority to FTP website traffic received on the precise serial interface. We display find out how to do that utilizing the two the old and new configuration methods.
This might seem to be a fairly synthetic illustration. Just after all, why would you care about tagging inbound targeted traffic that you have definitely received from a low-speed interface? In reality, among the most significant rules for applying QoS in the network is you might want to consistently tag the packet as early as is possible, preferably with the edges for the network. Then, as it passes from the network, each router only needs to consider the tag, and will not really need to do any supplemental classification. In cases like this, we'd be certain that the FTP targeted visitors returning inside the other administration is tagged because of the to begin with router that gets it. And so the outbound site traffic has already been tagged, and it's a waste of router sources to reclassify the outbound packets.

Countless organizations basically take this idea of marking in the edges a single move further more, and remark every last acquired packet. This assists to ensure that customers are not requesting amazing QoS privileges which they aren't authorized to acquire. Even so, you should be watchful of this since it could possibly occasionally disrupt reliable markings. By way of example, a real-time application may perhaps use RSVP to order bandwidth with the network. It's very important the packets for this application possess the ideal Expedited Forwarding (EF) DSCP marking or perhaps the network won't deal with them appropriately. At the same time, you also do not like to let other non-real-time programs from this same supply possess the same EF concern stage. So, if you are going to configure your routers to remark all incoming packets for the edges, confirm you have an understanding of what incoming markings are respectable.

In that scenario, the routers are jogging DLSw to bridge SNA traffic thru an IP network. Therefore the routers by themselves in reality design the IP packets. This results in an extra challenge as a result of you can find no incoming interface. So that recipe takes advantage of community policy-based routing. The fact which the router generates the packets also offers it a significant edge considering that it doesn't have to take into consideration any DLSw packets that might just come about to go through.

The advantages with the newer class-map method are not obvious in such a case in point, but one of the foremost massive benefits seems if you would like to utilize the greater present day DSCP tagging scheme. Since the mature policy-based routing system will not directly assist DSCP, you could have to fake it by environment each the IP Precedence along with the TOS separately as follows.

Router(config)#route-map serialftp-rtmap permit 10
Router(config-route-map)#match ip address 115
Router(config-route-map)#set ip precedence immediate
Router(config-route-map)#set ip tos max-throughput

In this case, the packet will wind up with an IP Precedence value of immediate, or 2 (010 in binary), and TOS of max-throughput, or 4 (0100 in binary).

Doing the same thing with the class-map method is much more direct:

Router(config)#policy-map serialftppolicy
Router(config-pmap)#class serialftpclass
Router(config-pmap-c)#set ip dscp af21

Class-maps may also be advantageous afterwards on this chapter after we mention class-based weighted truthful queuing and class-based potential customers shaping.
It is important to note that during this entire illustration, we now have only put a wonderful price into your packet's TOS or DSCP area. This, by by itself, doesn't have an impact on how the packet is forwarded by means of the network. To complete that, it's essential to ensure that as every single router around the network forwards these marked packets, the interface queues will react appropriately to this data.

At long last, we should observe that even though this recipe displays two helpful tips of marking packets, making use of Committed Access Pace (Vehicle) characteristics. Automobile tends to be increased efficient on increased pace interfaces.

For before IOS variations, where by class-maps ended up not offered, you have to implement policy-based routing to change the TOS subject in a packet. Making use of this coverage into the interface tells the router to make use of this coverage to check all incoming packets on this interface and rewrite those that match the route map:Router#configure terminal

Earlier than you?ˉre able to tag a packet for distinctive therapy, you will have to have a particularly obvious concept of what forms of page views really want exclusive treatment method, not to mention precisely what sort of exclusive treatment method they may will want. From the illustration, we've chose to give a specific priority to FTP website traffic received on the precise serial interface. We display find out how to do that utilizing the two the old and new configuration methods.
This might seem to be a fairly synthetic illustration. Just after all, why would you care about tagging inbound targeted traffic that you have definitely received from a low-speed interface? In reality, among the most significant rules for applying QoS in the network is you might want to consistently tag the packet as early as is possible, preferably with the edges for the network. Then, as it passes from the network, each router only needs to consider the tag, and will not really need to do any supplemental classification. In cases like this, we'd be certain that the FTP targeted visitors returning inside the other administration is tagged because of the to begin with router that gets it. And so the outbound site traffic has already been tagged, and it's a waste of router sources to reclassify the outbound packets.

Countless organizations basically take this idea of marking in the edges a single move further more, and remark every last acquired packet. This assists to ensure that customers are not requesting amazing QoS privileges which they aren't authorized to acquire. Even so, you should be watchful of this since it could possibly occasionally disrupt reliable markings. By way of example, a real-time application may perhaps use RSVP to order bandwidth with the network. It's very important the packets for this application possess the ideal Expedited Forwarding (EF) DSCP marking or perhaps the network won't deal with them appropriately. At the same time, you also do not like to let other non-real-time programs from this same supply possess the same EF concern stage. So, if you are going to configure your routers to remark all incoming packets for the edges, confirm you have an understanding of what incoming markings are respectable.

In that scenario, the routers are jogging DLSw to bridge SNA traffic thru an IP network. Therefore the routers by themselves in reality design the IP packets. This results in an extra challenge as a result of you can find no incoming interface. So that recipe takes advantage of community policy-based routing. The fact which the router generates the packets also offers it a significant edge considering that it doesn't have to take into consideration any DLSw packets that might just come about to go through.

The advantages with the newer class-map method are not obvious in such a case in point, but one of the foremost massive benefits seems if you would like to utilize the greater present day DSCP tagging scheme. Since the mature policy-based routing system will not directly assist DSCP, you could have to fake it by environment each the IP Precedence along with the TOS separately as follows.

Router(config)#route-map serialftp-rtmap permit 10
Router(config-route-map)#match ip address 115
Router(config-route-map)#set ip precedence immediate
Router(config-route-map)#set ip tos max-throughput

In this case, the packet will wind up with an IP Precedence value of immediate, or 2 (010 in binary), and TOS of max-throughput, or 4 (0100 in binary).

Doing the same thing with the class-map method is much more direct:

Router(config)#policy-map serialftppolicy
Router(config-pmap)#class serialftpclass
Router(config-pmap-c)#set ip dscp af21

Class-maps may also be advantageous afterwards on this chapter after we mention class-based weighted truthful queuing and class-based potential customers shaping.
It is important to note that during this entire illustration, we now have only put a wonderful price into your packet's TOS or DSCP area. This, by by itself, doesn't have an impact on how the packet is forwarded by means of the network. To complete that, it's essential to ensure that as every single router around the network forwards these marked packets, the interface queues will react appropriately to this data.

At long last, we should observe that even though this recipe displays two helpful tips of marking packets, making use of Committed Access Pace (Vehicle) characteristics. Automobile tends to be increased efficient on increased pace interfaces.

Ideal CCIE Coaching plus the appropriate solution to get CCIE Certification CCIE Training

There just isn't a need to have one other qualified exercise or class certificates to qualify. The CCIE Stability workout is made of a developed examination to qualify and then the lab examination. You may be recommended to receive at the least 3-5 yrs of employment know-how before than trying this certification.

The examination for your CCIE Protection is of two-hour length with numerous possibilities. This consists of hundred problems, that will go over subjects equal to software program protocols, working systems, safety technologies, protection protocols, and Cisco basic safety apps. The exam materials are offered about the spot and you aren't permitted to usher in exterior reference substances.

Network engineers having a CCIE certificates are considered since the expert within the local community engineering self-discipline and the masters of CISCO merchandise. The CCIE has brought revolution inside of the community market regarding technically hard assignments and selections with the necessary instruments and methodologies. There is a method which updates and reorganizes the instruments to produce high-quality services. There are actually varying modes of CCIE Exercise like authored examination planning and performance primarily based lab. This helps to strengthen the effectivity and common of the market place. CISCO has launched this certification coverage in 1993 by having a see to differentiate the very best analysts with the relaxation.

In order to be licensed, earliest written examination have got to be passed soon after which must cross the lab test. CISCO in the slightest degree days tries to use absolutely distinctive CCIE Instruction processes for increased effectiveness. There are a variety of strategies for that CCIE certification. The very first phase for certification is usually to pass a two hours lasting computer centered primarily MCQ oriented composed examination. For this examination important payments need to be completed by way of over the internet. This examination is connected with exam vouchers and promotional codes. The authenticity within the voucher furnishing agency should be properly identified towards the candidates. The promotional code will be accessed appropriately and just in case of fraudulent vouchers along with promotional codes should not satisfactory and CISCO won't repay the value. The candidates should wait around five days for your written examination immediately after cost and they can't sit for the exact same test for your subsequent 100 eighty days in the event of recertification.

By using a watch to get certified and eligible for your CCIE Exercise some things are for being remembered effectively. As a result of passing the written examination the candidates have a very almost all of 18 months time for making an attempt the lab exam. When the time period exceeds then the authenticity in the prepared examination would be invalid. For that 1st timer applied to get CCIE certification the authored test is available within the sort of Beta examination with special discounts obtainable. Inside the Beta period of time the candidates can sit only as soon as for your exam. The results will arrive inside 6 to 8 weeks soon after the examination is over.

The following phase for the CCIE certification certainly is the Lab examination. The shortlisted candidates for the penned exam can solely implement for the fingers-on lab exam. Nevertheless there are lots of created examination centers of CISCO however Lab examination amenities are limited. You'll find it an 8 hour fingers-on practical based mostly generally examination whereby the ability of troubleshooting and configuring local community generally dependent problems and applications are checked. For your scheduling of Lab examination the shortlisted candidates of your previously penned test needs to present the identification amount alongside passing rating also, the date of passing.

The price for Lab examination has to be cleared before than ninety days for the scheduled test. With out the price the reservation might possibly be cancelled. Immediately after passing the Lab examination mixed while using the developed check the candidates can use for the CCIE certification. By contemplating many of the details involved considering the mentioned guidelines, one can get the CISCO certification in hand and be experienced for the CCIE Education.

The solution to this difficulty is dependent upon the sort of potential customers distinctions you are looking for to create, at the same time the model of IOS you may be managing inside of your routers.

There ought to be a little something that defines the various types of potential customers you want to prioritize. In most cases, the simpler the distinctions are to produce, the higher. It's because each of the checks take router sources and introduce processing delays. The commonest rules for distinguishing in between potential customers types utilize the packet's input interface and basic IP header detail this sort of as TCP port figures. The following examples display the way to set an IP Precedence value of instantaneous (two) for all FTP command traffic that arrives because of the serial0/0 interface, and an IP Precedence of concern (1) for all FTP data targeted traffic. This distinction is possible as FTP regulate visitors uses TCP port 21, and FTP information uses port 20.

The newest process for configuring this uses class maps. Cisco 1st launched this feature in IOS Version twelve.0(five)T. This method first defines a class-map that specifies how the router will discover this type of site traffic. It then defines a policy-map that truly makes the modifications for the packet's TOS industry:
