HOW TO GET THE CCIE

AutoQoS is an extremely useful feature that can take a lot of the mystery out of building a QoS policy. Unfortunately, there are several restrictions on this feature that you need to be aware of.

First, it is only available on point-to-point links between routers. This includes point-to-point subinterfaces on ATM and Frame Relay PVCs, as shown in the example. The feature is also available on PPP and HDLC Serial connections. It cannot be used on any multiple access media, including Ethernets, or multipoint subinterfaces.

Second, it can't be used with any virtual templates or frame map statements. It cannot be used with either Frame Relay or ATM SVCs.

Third, it must be enabled on both ends of each link or PVC. This doesn't necessarily mean that both routers must run the same IOS version, however, as long as the AutoQoS feature is available on both routers.

Fourth, you should disable any other service policies or access-groups on the router, even if they are associated with different interfaces.

And finally, you must ensure that CEF is enabled for this feature to work.

AutoQoS for VoIP was introduced in IOS Version 12.2(15)T. This command is actually a macro that adds a series of commands to your router's configuration. You can use the show auto qos command to see exactly what it has added:

Router1#show auto qos

Router1#

Clearly, this little macro has done a lot of work, and in fact this command output doesn't show the class-maps that were created at the same time! Let's examine what it did. First, it created a policy-map called AutoQoS-Policy-UnTrust, which allocates up to 70% of the bandwidth on this link to voice traffic and another 5% to VoIP control packets. It also sets the DSCP values for these traffic streams, overriding whatever values were previously in the packets. All other traffic is configured to use weighted fair-queuing (WFQ).

Then, skipping over the access-lists, whose purpose is fairly clear, the macro has created an RMON rule that will automatically send an SNMP trap every time the router is forced to drop a voice packet. You can then use these trap logs to determine if the queuing parameters are appropriate. If you find that you are dropping a lot of packets, then you may need to increase your bandwidth to reduce congestion.

And finally, it has implemented Frame Relay Traffic Shaping to ensure that the router doesn't attempt to overrun the CIR for the PVC. This is a critical consideration because, by default, the router will assume that it can transmit at wire speed on each PVC individually. So if you have several PVCs on a single physical circuit, it will allow any of them to burst to the full bandwidth capacity of the interface, possibly over-running the CIR of the PVC. As a result, even with the best queuing strategy on the router, you could find yourself dropping packets in the frame cloud.

The AutoQoS for the Enterprise feature was introduced in IOS Version 12.3(7)T. It classifies traffic into 10 categories, which are listed in Table 11-2. Note that if the discovery feature doesn't see any traffic of a particular type, then AutoQoS will not create a corresponding class on the router.

Table 11-2. AutoQos traffic classes
Class Name	DSCP	Description
IP Routing	CS6	Routing protocol and ICMP traffic
Interactive Voice	EF	RTP Voice traffic
Interactive Video	AF41	RTP Video traffic
Streaming Video	CS4	Various streaming audio and video protocols, such as CU-SeeMe, RealAudio, and Netshow
Telephony Signaling	CS3	RTP and H.323
Transactional/Interactive	AF21	Database protocols, such as SAP, SQLNet, and SQLServer, as well as interactive protocols, including Citrix, Telnet, Notes, SSH, and X11
Network Management	CS2	Primarily SNMP
Bulk Data	AF11	Batch file transfer protocols such as FTP, Exchange, POP3, SMTP, NNTP, and network printing
Scavenger	CS1	Various peer-to-peer and entertainment protocols, including Napster, Fasttrack, and Gnutella; this group is given a worse than best-efforts priority
Best Effort	0	Various miscellaneous protocols, including HTTP, NFS, SunRPC, NTP, and gopher, as well as any unidentified traffic

We enabled auto discovery QoS on both ends of a Frame-Relay PVC, ran some traffic through the link and then looked at the output of the show auto discovery qos command to see what the router suggested for a QoS policy:

As you can see, we didn't let the discovery phase run for very long, and consequently did not discovery very many types of traffic. The router saw no traffic in the Voice, Interactive Video, Telephony Signaling, Streaming Video, Bulk, or Scavenger classes. But it did see some TELNET traffic in the Transactional class, some SNMP traffic in the Network Management class, as well as some Routing Protocol and Best Efforts traffic. Note that the command output includes average and peak rate traffic statistics, which the router will use to help determine queuing parameters:

Class Best Effort:

  Current Bandwidth Estimation: 3 Kbps/<1% (AverageRate)

  Detected applications and data:

  Application/       AverageRate        PeakRate           Total

  Protocol           (kbps/%)           (kbps/%)           (bytes)

  http               3/<1               33/2               84777

  unknowns           0/0                0/0                184

The output then ends with a suggestion for a QoS policy-map to be applied to this interface. This output shows that the AutoQoS feature uses the NBAR match command to identify protocols. NBAR is the basis of AutoQoS.

Once we are satisfied that this is a good QoS policy, we enable it by using the auto qos command:

Router1(config)#interface Serial0/0.1 point-to-point

Router1(config-subif)#frame-relay interface-dlci 904

Router1(config-fr-dlci)#auto qos

%Creating new map-class.

Router1(config-fr-dlci)#no auto discovery qos

Router1(config-fr-dlci)#exit

Router1(config-subif)#exit

It is critical to enable AutoQoS before disabling the discovery feature. Otherwise, the router will lose all of the traffic information that it has learned.

If you want to see the new configuration commands that AutoQoS has added to your router, use the show auto qos command:

Router1#show auto qos

 !

 policy-map AutoQoS-Policy-Se0/0.1

  class AutoQoS-Transactional-Se0/0.1

  frame-relay be 0

  frame-relay mincir 1544000

  service-policy output AutoQoS-Policy-Se0/0.1-Parent

Router1#

Note that the actual policy map does not exactly match the version that we saw earlier during the data collection phase. The biggest difference is that the router saw some additional RIP traffic in the meantime and added this protocol to the class called AutoQoS-Routing-Se0/0.1. It has also created a Frame Relay map class that includes traffic shaping parameters for the PVC.

Because AutoQoS adds so many different commands to the router configuration, if you want to disable AutoQoS, it is not sufficient to just remove the auto qos command. You will need to remove all of the other commands separately. In fact, you should be careful about removing this command because if you do so, the show auto qos command will no longer function, making it much more difficult to figure out what commands are actually related to this feature. To make matters worse, once you have removed the auto qos command, you can't even put it back because the router needs to repeat the discovery phase first!

If you want to remove this feature after you have enabled it, we recommend capturing the output of the show auto qos command and using a text editor to create a configuration script that selectively eliminates all of the associated commands.

AutoQoS for the Enterprise can be a useful way of generating a detailed queuing strategy for your network. We do urge some caution in using this feature, however. In our experience, the discovery option can be unreliable. In particular, if you are using NBAR or have access-groups enabled on the router, this can interfere with the data collection. Furthermore, we have seen questionable results in the output that went away after disabling and re-enabling the discovery option.

We strongly recommend looking very closely at the recommendations made by this command before implementing them.

It truly is aimed to pick the professionals within the networking small business for the famend agency supplying methods into the technical departments. By using a goal to acquire CCIE certification the candidates must transfer by two necessary preference tests. To start with, the written check is usually to be handed when which the candidates can sit for the Lab examination. The brief-listed candidates can solely have CCIE certification. In an effort to prepare for your CCIE exams, CCIE Bootcamp is built.

CCIE Bootcamps offer you effectively essentially the most effortless method of passing out the checks of CCIE. You will discover plenty of firms reasonably institutes which provide CCIE Bootcamp education comparable to Cathay College. Which has a look at to mature to be qualified for your bootcamps the institutes in many cases existing a prerequisite. It can help to spice up the prospect of your applicants to maneuver the CCIE exams in a very larger way than people. This prerequisite is known as CCNP status.

The involved price for taking the CCIE Security exam is substantial, so most candidates go for a preparing study course to cross it in one sitting. Some impartial companies and institutions offer programs and workshop to all those selecting CCIE Stability workout. Nevertheless, most candidates prefer to utilize the instructor-led and on-line workshops, which Cisco offer, like a portion of Licensed Researching Companions system. The exercise choices are offered along with the educators are acknowledged by Cisco.

For that CCIE Safety certification, you ought to register for the penned examination as part of your area of specialization. Many of the exams are done on the Cisco licensed facility, which also accepts expenditure for that test. The cost of taking a CCIE prepared examination is from $80 to $325. The developed exam is supervised and executed on a laptop computer. It's of one or two hrs paper that contains a number of picks, drag and drop doubts and fill within the blanks. Aside from white boards and markers for calculations, as being a candidate for CCIE Stability coaching examination, you aren't allowed to hold almost every other item for the test hall.

CCIE Bootcamp is accompanied using a amount of practices to provide the simplest preparation materials to your students. They primarily provide you with some must-have publications to organize them for your penned CCIE take a look at collectively with some world-wide-web entry for the Lab exam. Relying on these two categories the CCIE Bootcamps is divided into two sections. The divisions are class building and also Lab simulation. The category construction consists of two phases and they are fingers-on coaching and lectured-based mostly classes. Inside the category framework the pupils are presented while using data of Little bit splitting, VLSM and many others. However the lab simulation is necessary component of CCIE Bootcamp. Right here the students are subjected to cope with a variety of real-life issues along with the troubleshooting abilities are checked the right way. That is definitely the greatest stage of CCIE Bootcamps the location the scholars are nicely-prepared for your Blueprintv4, MPLS and so on. These methodologies allow pupils to troubleshoot any real-life concerns and increase the facility to find out the proper alternatives.

But you will discover handful of dependable institutes obtainable on the market around the promote which offers entire CCIE Bootcamps. One in every of a great deal of properly-renowned institutes is Cathay Faculty which renders especially beneficial services in case of bootcamps for CCIE. They provide bootcamp facilities to relatively sizable variety of university pupils from plenty of corners on the planet like Australia, Norway, Uk, Sweden, USA and countless extra. In accordance using the data of this institute from 2005, they're sustaining doc variety of proportion of passing price in CCIE examination. This file is itself a kind of guarantee for them. There are various leads to to pick out Cathay College for CCIE Bootcamps. The report quantity of passing pace of almost 90% is the most captivating purpose of it. Aside from it, 1 other fantastic attribute may be the one-to-one lab coaching which support the college students to filter out all the doubts relating to any downside from your instructors.

The necessary facts associated with the bootcamp is available into the trustworthy enterprise page and that is cathayschool.com. It is a extremely easy site which supplies many placing facilities like on-line Self-Study CCIE Lab Workbooks, one-on-one on the net coaching, Teacher Led exercise etc. All the facilities as well as the class durations jointly when using the money are effectively-described here like that the potential consumers really should not ought to confront any form of trouble regarding CCIE Bootcamps.

The NBAR feature is used to identify traffic within a class-map. You can then use the class-map in a policy-map to define how the router should handle each application data stream:

Router1#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router1(config)#ip cef

Router1(config)#class-map INTERACTIVE

Router1(config-cmap)#match protocol citrix

Router1(config-cmap)#match protocol telnet

Router1(config-cmap)#exit

Router1(config)#policy-map QoSPolicy

Router1(config-pmap)#class INTERACTIVE

Router1(config-pmap-c)#bandwidth percent 50

Router1(config-pmap-c)#set dscp ef

Router1(config-pmap-c)#exit

Router1(config-pmap)#class class-default

Router1(config-pmap-c)#bandwidth percent 20

Router1(config-pmap-c)#random-detect dscp-based

Router1(config-pmap-c)#exit

Router1(config-pmap)#exit

Router1(config)#interface FastEthernet0/0

Router1(config-fi)#service-policy inbound QoSPolicy

Router1(config-if)#exit

Router1(config)#end

Router1#

Cisco also offers the ability to download specialized Packet Description Language Module (PDLM) files onto the router's flash device, and then activate them for use with NBAR classification:

Router1#show flash

System flash directory:

File  Length   Name/status

  1   23169076  c2600-ipvoice-mz.124-10.bin

  2   3100     bittorrent.pdlm

[23172304 bytes used, 9857836 available, 33030140 total]

32768K bytes of processor board System flash (Read/Write)

Router1#Router1#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router1(config)#ip nbar pdlm flash://bittorrent.pdlm

Router1(config)#class-map BITTORRENT

Router1(config-cmap)#match protocol bittorrent

Router1(config-cmap)#exit

Router1(config)#end

Router1#

And you can also use NBAR to automatically profile the protocols on a particular interface:

Router1#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router1(config)#interface FastEthernet0/0

Router1(config-if)#ip nbar protocol-discovery

Router1(config-if)#exit

Router1(config)#end

Router1#

Network Based Application Recognition (NBAR) is an extremely useful feature that first became available in IOS Version 12.0(5)XE2, and more generally in 12.1(5)T. Cisco continues to add new protocols to NBAR, allowing you to categorize more and more different traffic streams on your network. The one caveat to using NBAR is that it can introduce a heavy additional load on your router's CPU. We recommend monitoring the CPU utilization after implementing any NBAR-based filtering, at least until you are confident that the router is not straining under the additional load.

The basic syntax is to set up a class-map, and then use the match protocol command with the appropriate keyword:

Router1(config)#class-map INTERACTIVE

Router1(config-cmap)#match protocol citrix

Router1(config-cmap)#match protocol telnet

We used Citrix as an example protocol in this recipe because it is a classic example of the need for the NBAR feature. This is a proprietary protocol that is used in thin-client architectures. The end user's workstation is just a terminal that displays graphical information from the screen of a centrally located computer running a virtual desktop for the user. The protocol transmits graphical information and keystrokes. Because it is an interactive application, it needs to be given high priority through the network. However, it is notoriously difficult to reliably identify from Layer 3 and 4 information:

As the example shows, you can then use this class in a policy-map:

Router1(config)#policy-map QoSPolicy

Router1(config-pmap)#class INTERACTIVE

Router1(config-pmap-c)#bandwidth percent 50

Router1(config-pmap-c)#set dscp ef

Router1(config-pmap-c)#exit

NBAR classifies applications at the application layer, allowing you to differentiate between different streams of traffic that may actually use the same UDP or TCP port numbers, as well as streams of traffic that may use a variety of ports or even arbitrary port numbers.

Router1(config-cmap)#

You can obtain and install new PDLM files from Cisco. In the example, we have downloaded a new PDLM file that can identify the BitTorrent protocol. Once we put this file on the router's Flash device, we need to tell NBAR to load the file to make it available:

Router1(config)#ip nbar pdlm flash://bittorrent.pdlm

In the past, Cisco has also made PDLM files available to help network administrators to use NBAR to help to identify hostile applications such as viruses and worms.

We are not aware of PDLM files originating from sources other than Cisco, but we strongly recommend that you use only files that you obtain directly from Cisco. Otherwise, you could potentially open your network to serious security vulnerabilities.

We note in passing that Cisco has also added the option to manually create your own NBAR rules using the ip nbar custom command. This feature should allow you to, for example, define a new protocol by specifying TCP or UDP port numbers, as well as any special rules that look for identifiable content at a particular bit offset in the packet payload. However, the syntax for this feature is confusing, and the parser is apparently unstable in some IOS versions, so we don't currently recommend using it.

The last feature discussed in the Solution section of this recipe is the NBAR Protocol-Discovery feature. This is a useful tool for figuring out what is going through your network, particularly if you are trying to define a QoS strategy. You can use the show ip nbar protocol-discovery command to get detailed statistics on the utilization for every type of protocol that NBAR understands. However, NBAR now supports so many protocols that this complete list is often not very useful for spotting trends. Instead, we suggest using the top-n keyword with a relatively small argument number, such as 5, or at most 10. This will allow you to immediately see statistics for the top protocols for each interface on which you enabled the feature:

Router1#show ip nbar protocol-discovery top-n 5

To redistribute static routes into an OSPF process, use the redistribute static configuration command:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#ip route 192.168.10.0 255.255.255.0 172.22.1.4
Router1(config)#ip route 172.24.1.0 255.255.255.0 172.22.1.4
Router1(config)#ip route 10.100.1.0 255.255.255.0 172.22.1.4
Router1(config)#router ospf 55
Router1(config-router)#redistribute static
% Only classful networks will be redistributed
Router1(config-router)#exit
Router1(config)#end
Router1#
As the warning message indicates, OSPF will only redistribute classful network routes by default. In the example, we included three static routes. Of these routes, only 192.168.10.0/24 is classful. If we then look at the routing table on a different router, we can see that the other two routes are not present:
Router5#show ip route ospf

You can ensure that all routes are redistributed, regardless of whether they are classful or not, by including the subnets keyword:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#router ospf 55
Router1(config-router)#redistribute static subnets
Router1(config-router)#exit

As you can see, all three static routes are advertised now:

Another useful thing to notice about this output is the fact that all of these external static routes are marked as type E2, meaning that they are external routes of Type 2. As we discussed in the Introduction to this chapter, any time you distribute a foreign route into OSPF, it is always considered external. This helps OSPF to ensure that it doesn't create any loops through an external network when there are multiple connection points.
When OSPF distributes Type 2 External routes, it doesn't add the internal link cost to the net route cost. OSPF always prefers Type 1 to Type 2 External routes because Type 1 routes do include the internal path cost in the metric. If you want to distribute static routes as Type 1 instead of the default type 2, you need to include the metric-type keyword in the redistribute static command:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#router ospf 55
Router1(config-router)#redistribute static subnets metric 40 metric-type 1
Router1(config-router)#exit
Router1(config)#end
Router1#
In this example, we have also set the default metric for these static routes to a value of 40. Notice that the next hop router now shows the total cost of the path as 60 because it now includes the internal link cost of 20:
Router5#show ip route 192.168.10.0
