Ask the Expert: Scaling Data Center Networks with Cisco FabricPath

With Hatim Badr and Iqbal Syed
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about the Cisco FabricPath with Cisco technical support experts Hatim Badr and Iqbal Syed. Cisco FabricPath is a Cisco NX-OS Software innovation combining the plug-and-play simplicity of Ethernet with the reliability and scalability of Layer 3 routing. Cisco FabricPath uses many of the best characteristics of traditional Layer 2 and Layer 3 technologies, combining them into a new control-plane and data-plane implementation that combines the immediately operational "plug-and-play" deployment model of a bridged spanning-tree environment with the stability, re-convergence characteristics, and ability to use multiple parallel paths typical of a Layer 3 routed environment. The result is a scalable, flexible, and highly available Ethernet fabric suitable for even the most demanding data center environments. Using FabricPath, you can build highly scalable Layer 2 multipath networks without the Spanning Tree Protocol. Such networks are particularly suitable for large virtualization deployments, private clouds, and high-performance computing (HPC) environments.
This event will focus on technical support questions related to the benefits of Cisco FabricPath over STP or VPC based architectures, design options with FabricPath, migration to FabricPath from STP/VPC based networks and FabricPath design and implementation best practices.

Hi Sarah,
Thank you for your question.
Spanning Tree Protocol is used to build a loop-free topology. Although Spanning Tree Protocol serves a critical function in these Layer 2 networks, it is also frequently the cause of a variety of problems, both operational and architectural.
One important aspect of Spanning Tree Protocol behavior is its inability to use parallel forwarding paths. Spanning Tree Protocol forms a forwarding tree, rooted at a single device, along which all data-plane traffic must flow. The addition of parallel paths serves as a redundancy mechanism, but adding more than one such path has little benefit because Spanning Tree Protocol blocks any additional paths
In addition, rooting the forwarding path at a single device results in suboptimal forwarding paths, as shown below, Although a direct connection may exist, it cannot be used because only one active forwarding path is allowed.
Virtual PortChannel (vPC) technology partially mitigates the limitations of Spanning Tree Protocol. vPC allows a single Ethernet device to connect simultaneously to two discrete Cisco Nexus switches while treating these parallel connections as a single logical PortChannel interface. The result is active-active forwarding paths and the removal of Spanning Tree Protocol blocked links, delivering an effective way to use two parallel paths in the typical Layer 2 topologies used with Spanning Tree Protocol.
vPC provides several benefits over a standard Spanning Tree Protocol such as elimination of blocker ports and both vPC switches can behave as active default gateway for first-hop redundancy protocols such as Hot Standby Router Protocol (HSRP): that is, traffic can be routed by either vPC peer switch.
At the same time, however, many of the overall design constraints of a Spanning Tree Protocol network remain even when you deploy vPC such as
1.     Although vPC provides active-active forwarding, only two active parallel paths are possible.
2.     vPC offers no means by which VLANs can be extended, a critical limitation of traditional Spanning Tree Protocol designs.
With Cisco FabricPath, you can create a flexible Ethernet fabric that eliminates many of the constraints of Spanning Tree Protocol. At the control plane, Cisco FabricPath uses a Shortest-Path First (SPF) routing protocol to determine reachability and selects the best path or paths to any given destination in the Cisco FabricPath domain. In addition, the Cisco FabricPath data plane introduces capabilities that help ensure that the network remains stable, and it provides scalable, hardware-based learning and forwarding capabilities not bound by software or CPU capacity.
Benefits of deploying an Ethernet fabric based on Cisco FabricPath include:
• Simplicity, reducing operating expenses
– Cisco FabricPath is extremely simple to configure. In fact, the only necessary configuration consists of distinguishing the core ports, which link the switches, from the edge ports, where end devices are attached. There is no need to tune any parameter to get an optimal configuration, and switch addresses are assigned automatically.
– A single control protocol is used for unicast forwarding, multicast forwarding, and VLAN pruning. The Cisco FabricPath solution requires less combined configuration than an equivalent Spanning Tree Protocol-based network, further reducing the overall management cost.
– A device that does not support Cisco FabricPath can be attached redundantly to two separate Cisco FabricPath bridges with enhanced virtual PortChannel (vPC+) technology, providing an easy migration path. Just like vPC, vPC+ relies on PortChannel technology to provide multipathing and redundancy without resorting to Spanning Tree Protocol.
Scalability based on proven technology
– Cisco FabricPath uses a control protocol built on top of the powerful Intermediate System-to-Intermediate System (IS-IS) routing protocol, an industry standard that provides fast convergence and that has been proven to scale up to the largest service provider environments. Nevertheless, no specific knowledge of IS-IS is required in order to operate a Cisco FabricPath network.
– Loop prevention and mitigation is available in the data plane, helping ensure safe forwarding that cannot be matched by any transparent bridging technology. The Cisco FabricPath frames include a time-to-live (TTL) field similar to the one used in IP, and a Reverse Path Forwarding (RPF) check is also applied.
• Efficiency and high performance
– Because equal-cost multipath (ECMP) can be used the data plane, the network can use all the links available between any two devices. The first-generation hardware supporting Cisco FabricPath can perform 16-way ECMP, which, when combined with 16-port 10-Gbps port channels, represents a potential bandwidth of 2.56 terabits per second (Tbps) between switches.
– Frames are forwarded along the shortest path to their destination, reducing the latency of the exchanges between end stations compared to a spanning tree-based solution.
    – MAC addresses are learned selectively at the edge, allowing to scale the network beyond the limits of the MAC addr

Hi Dennis,
    All those Layer 2 extension technologies require STP to be extended between Data Centers if you need to have multiple paths between Data Centers. OTV does not extend STP rather it has its own mechanism (AED election) to avoid loop when multiple paths are enabled. It means any STP control plane issue, we don't carry to the other Data Center.
    OTV natively suppresses Unknown Unicast Flooding across the OTV overlay. Unknown unicast flooding is a painful problem in layer 2 network and difficult to troubleshoot to identify the root cause if you don't have proper network monitoring tool.
   It has ARP optimization which eliminates flooding ARP packets across Data Center by responding locally with cached ARP messages. One of the common issues I have seen in Data Center is some server or device in the network sends continuous ARP packets which hits Control plane in the Aggregation layer which in turn causes network connectivity issue.
The above three points proves the Layer 2 domain isolation between data centers. If you have redundant Data Centers with Layer 2 extended without OTV, the above explained layer 2 issue which happens in one Data Center carries the same failure to the second data center which creates the question of what is the point of having two different Data Centers if we can not isolate the failure domain.
OTV natively supports HSRP localization with few command lines. This is a very important requirement in building Active/Active Data Center.
Even though your question is related to L2TP, OTV deserves the comparison with VPLS and those comparison will also be applicable for L2TP. The below link explains in detail...

Scheduling with Forecast Dates

Dear Experts,
I want to know whether following is possible.
When creating a project initial schedule dates based on Activity Duration and Activity Relationships should reflect as Basic Dates. After project creation, when ever the Project Manager reschedule the project, those reschedule dates should be reflect as Forecasted dates.
By doing this the Project Manager will be able to identify Initial Plan as Basic Dates, Reschedule Plan as Forecasted Dates and Actual as Actual Dates.
Very Much Appreciate your Support,
Dileepa.

Dear All,
I did reschedule Forecasting Dates using CN24 (Overall Network Scheduling) transaction. But after doing this, overall Project and WBS Elements dates does not changes based on the reschedule Network Time lines.
Further I have define "Network determines dates" as the Scheduling method in WBS Schedule Profile.
Very much appreciate your guidance,
Dileepa.

WBS Forecast dates disappears during scheduling after final confirmation

Hi dear Experts.I faced a problem with WBS dates.
The system overwrites forecast and basic dates on WBS after final confirmation of attached activities. And start to schedule wbs dates from dates of activities with no confirmation. Is there any way to solve this prolem?
In other words i need my WBS to take into scheduling ALL the operations forecast date. Moreover how the system can overwrite the forecast dates wich were entered manually by user?
Green - actual dates
Yellow (orange) - forecast dates
Bue - Basic dates
Please help.

Hi Kirill,
Please check the control parameters for WBS Scheduling. Check if the scheduling method over here is WBS Determines Dates. If this is the case, irrespective of the scheduling that was carried out at the activity level, the system overwrites the basic and forecast dates present at the WBS level. May be in your case the scheduling method that had been used was "Network determines dates".
. Please change this and let me know if this helps.
Regards
Varun

Forecast Date Usage

Dear All,
What is the use of Forecast dates and basic dates?
How can we compare Basic Dates, Forecast Dates and Actual dates.
Can we compare dated with delay in the project planning Board in deifferent colours and how?

Basic and Forecast Dates
Basic dates are the dates that have a binding character for time scheduling and for other related areas such as capacity planning.
Forecast dates are dates that you expect based on more detailed planning or on changes during the course of the project. Forecast dates have no influence on reservations, purchase requisitions, or current capacity requirements.
You can enter basic and forecast dates for WBS elements and activities. In networks, you can also forecast values for the work as well as for the dates.
You are free to decide which type of date you use for planning and scheduling. You can schedule a network using the forecast dates, for example, or you can copy the forecast dates into the basic dates in the WBS or activity and then use them as the basis for further planning.
Actual dates:
Actual dates provide you with information on the state of the project. You enter them manually in the WBS elements or the system calculates them using confirmation data.
Scheduled Dates
Scheduled dates are the start and finish dates of activities calculated by the system in scheduling. For WBS elements the scheduled dates are determined from the scheduled dates of the activities that are assigned to the WBS element.
Earliest and Latest Dates
Earliest and latest dates are calculated in network scheduling and tell you the earliest or latest data that an activity must start or finish on.
To compare the dates:
In Project planning board, click on "Set of Dates/View" button which can be found besides Options button.
Then Check the required dates.
Dates will be shown in different colours, you can compare them visually and get the amount delay.
If you are not sure about the colours, just click on Legend button to see which colour represents what.

How do i use my time capsule and extend the network with airport express

I have a new iMac and Time Capsule, how do i extend the network with airport express. My time capsule does have a guest net work, and logins and passwords? I am no computer person. So for me it would have to be spelled out.

Use the search as this has been done to death ..
Bob Timmons is the expert on this.. look at his answers here.
https://discussions.apple.com/thread/4274187?start=0&tstart=0
https://discussions.apple.com/message/21856077#21856077
This has been automated in the v6 utility. I am used to doing it manually in v5 utility which is also fairly easy.
Apple doco is also good to read.
http://support.apple.com/kb/HT4145
http://support.apple.com/kb/HT4259
Note.
You cannot extend the guest network unless everything is up to date 7.6.3 firmware. And that is only with the TC as the main router in the network.
All apple routers can be configured as the main wireless or as the extend wireless.. so don't worry if a post uses express or extreme or TC.. they are for wireless, the same thing.

Windows 8.1 Data reordering issue with Intel Adaptors

According to Intel, there is a data reordering issue with their adaptors and probably this dumb WIDI software. This is from Intel site. they say some are fixed, "A future Windows 8 fix will address this issue for other Intel wireless adapters." I
have one Nope, still broke. I get drops all the time. Brand new Toshiba laptop I7 16 gigs of ram and a SSD and a 2 gig Vid card. Would be nice to be able to play games but I get dropped all the time. Now would Microsoft quit hiding
about this, and fix the darn thing. Also i'm a system admin for 13 years. I have build over 1000 PCs and servers. I know bad software. Please fix this. PLEASE. Its not going to just go away and its not just Toshiba, I have seen other companies with the
same problem. If there is a Fix PLEASE POST IT. Or even a workaround I have tried everything.

Yep didn't work. Still get drops all the time, had to run a Cat 5E cable to my laptop from my modem, because I have Atheros Gigabyte Lan adaptor. Works Great. The Wireless still drops all the time. Has Microsoft let out the patch to fix this or is it coming in
April in the 8.1 patch that's coming. Funny thing is all for Widi, I don't even use widi, I got the software to do that from Samsung works better on my TV. Intel and Microsoft need to get this fixed. because their driving off gamers and that's the
people that make sure they buy Microsoft so they can play games. With the wireless link dead and a great laptop worthless what's the point. Ive been in IT for 13 years building PCs and Servers how I knew how to run a 60 FT Cat 5e line thru
a 2 story house and terminate it. Most people don't. Fix the problem.

Windows 7 and Networks with High Latency

We are currently trying to rollout Windows 7 on our network to replace XP but have encountered an issue whereby we have remote clients that access the network over high-latency satallite links (BGAN and Vocality/Satellite). The latency of the links (based
on ping results) can be 600ms for Vocality and 1-3s for BGANs.
The particular services that don't work are a full motion video solution using TVI Viewer 7.9.1 and Outlook 2003 or 2007. These work fine on Windows XP. Shares can be accessed but are significantly slower than XP and ping does respond fine.
Windows 7 is running on Panasonic Toughbook CF52 and CF74 and I've tested in with a vanilla install with no updates and not on the Domain (2008R2 native) to eliminate GPO interference and tried it with all MS updates as of about 2 months ago.
I've tried removing the extra services on the network card (Topology Discovery, ipv6 and QoS), updated to the latest NIC drivers from Panasonic and drivers from Intel themselves. Reduced the MTU to as low as 500 and increased the Frame size (I forget what
to but was following a guide for slow links).
I've successfully replicated the issue on out development system using a satallite simulator.
Windows 7 with Outlook and TVI work fine on our network when connected via the LAN, ADSL, 3G and WiFi.
I'm currently analysing Wireshark captures but they don't seem any different to the XP ones.
Any help would be much appreciated.

Hi,
I noticed that your issue just happened when you use satellite transmission connection.
The fact is that this kind of connection in Windows 7 use TCP protocol. Transmission Control Protocol ( TCP ) under ideal conditions can provide reliable data delivery, but it is inherent in the existence of a throughput bottleneck, with the emergence on
the long-distance WAN packet loss and latency increases, the bottleneck is becoming more prominent and serious. In satellite networks with high loss, effective throughput may be as low as 0.1% - 10% of available bandwidth.
However, FASP can be the solution.

How can I extend my wireless network with the Time Capsule?

I recently bought a Time Capsule and set it up, backed up all my data, etc. It is currently plugged in to my AT&T Uverse wireless router via a LAN CAT5e cable. I am wondering if it is possible to wirelessly extend my preexisting network with the Time Capsule so I can move it somewhere else in my house where it can still pick up the signal but extend it. And if possible, how so? Or does it ALWAYS have to be wired'connected to my router for the internet to work?
Thanks in advance.

I am wondering if it is possible to wirelessly extend my preexisting network with the Time Capsule so I can move it somewhere else in my house where it can still pick up the signal but extend it.
Sorry but no. Extending using only wireless would require that the Time Capsule connect to another Apple router that is producing the wireless network.
Another way of saying the same thing is that you must have two Apple routers to be able to extend the signal wirelessly.

Copying basic dates to forecast dates

Hi Experts,
I am using WBSE and activities in my project. I want to copy basic dates to forecast dates. But, when i am doing this in Edit>Reconcile date->Transfer basic dates to forecast dates. Then my Planning type in network header also gets change from Basic date to forecast date. which i don't want. I just want that my basic dates get copied to forecast dates , so that i can use forecast dates as my planed dates through the project and never change it. So, that i can always compare , basic dates, forecast dates and actual dates.
Thanks.

May be you can try the following....
1) Edit>Reconcile date->Transfer basic dates to forecast dates.
2) manually change Planning type in network header from forecast date to Basic date.

Send encryption data through network

I'm doing encryption data exchanging project. I can describe my scenario anyone can give me good suggestion.
I use RSA Key pair. Client side encrypt the data using private key and server decrypt those data using particular public key. I store my keys in keystore. For one attempt I use public and private keys belong to one alias. My problem is when doing decryption in server side I got error message (BadPaddingException: Data must start with zero). But if I do encryption and decryption in same class using same keys without any client/server connection it works properly.
So, if anyone can give me any advice or suggestion, I'm very appreciat

ivanovpv wrote:
I think problem is somewhere in data transmission. During transmission either server or client adds extra padding information.No. For symmetric block based encrypted the clear text has to be padded to make it a full block. This is normally done as part of the encryption process using PKCS5 padding. Padding is also reqired for RSA encryption so as to make sure the cleartext ^ public_exponent is greater than the modulus. This is normally done using PKCS1 padding.
If the encrypted data is corrupt then one normally gets a exception such as BadPaddingException when decrypting using a symmetric algorithm or an exception indicating that the padded data should start with a zero in the case of RSA encryption.
It is almost certain that the OP has corrupted his encrypted data or his key, possibly by converting to a String without using Hex or Base64 encoding. Without seeing his code we will probably never know.
>
I would suggest just get your public key (i hope it's just a long/String probably wrapped within some class) then explicitly convert it into character array (best is to use UTF-8 encoding) - then transmit through network. On other side decode from UTF-8 character array into long/String - probably you'd need to instantiate public key object from your long/String and enjoy!String should never be used as a container for binary data and keys are binary data. Just converting them to a String specifying utf-8 will almost certainly corrupt them. If one must have a String version of any binary data whether it be a key or cipher text one should reversibly encode it using something like Base64 or Hex.
