Cisco ACE 4. 71. 0 Application Control Engine Appliance Deployment Guide V1.Release Table of Contents Introduction Preface.This document describes how to deploy the Cisco.ACE 4. 71. 0 Application Control Engine appliance.This document is intended for use by anyone deploying a pair of Cisco ACE 4.Z3uUwu0AwBI/hqdefault.jpg' alt='Failed To Load An Application Resource Adobe Reader' title='Failed To Load An Application Resource Adobe Reader' />Crossdomain loading may allow a remote SWF to have unintended access to the loaders domain and data.If the loading SWF imports the remote SWF file into its.Assumptions Cisco ACE is deployed in a routed mode design, but it should be relatively simple to use in bridged or one arm mode.Automatic failover is not desirable, so fault tolerant preemption is disabled.Cisco ACE 4. 71. 0 appliances are connected to Cisco Catalyst 6.Series Switches running Cisco IOS Software.Related Documents Cisco ACE 4.Design Guide Cisco ACE 4.High Availability Guide References.Failed To Load An Application Resource Adobe Reader' title='Failed To Load An Application Resource Adobe Reader' />Cisco ACE 4. Best Internet Security Freeware Software there. Online Reference Guides.Deployment Physical Topology.To increase application and infrastructure availability, the Cisco ACE 4.Gigabit Ethernet interfaces and Cisco ACE virtualization.These interfaces can be configured in a Port.Channel to create a single logical link between the Cisco ACE 4.Cisco Catalyst 6.Series Switches. Trunked VLANs can be used to carry all client and server messaging, management traffic, and fault tolerant communication.Connecting the Cisco ACE 4.Cisco Catalyst 6.Series Switch in this manner has several obvious advantages.It allows the creation of a single very high bandwidth logical link, helping ensure the highest level 4 Gbps of throughput possible on the Cisco ACE 4.It gracefully handles asymmetric traffic profiles typical of web architectures.It simplifies the interface configuration since the single Port.Channel and IEEE 8.Future upgrades, for example from 1 Gbps to 4 Gbps, can be accomplished in real time by installing a license for increased throughput without the need to physically recable the appliance interfaces.Individual Cisco ACE contexts are not limited by the throughput of a single 1 Gbps interface.Traffic can be shaped according to the available throughput at the context, virtual IP, or real server level rather than at the interface level.It allows the Cisco ACE to reach throughput license limits, including throughput limits additionally reserved for management traffic.By default, the entry level Cisco ACE appliance has a 1 Gbps through traffic bandwidth limit and an additional 1 Gbps management traffic bandwidth limit, resulting in a maximum bandwidth of 2 Gbps.Similarly, with the 2 Gbps license, the Cisco ACE has a 2 Gbps through traffic bandwidth limit and a 1 Gbps management traffic bandwidth limit, for a total maximum bandwidth of 3 Gbps.The Port. Channel provides redundancy should any of the four physical interfaces fail.The single logical link can support all the common deployment modes, including routed, bridged, one arm, and asymmetric server return, while also addressing high availability and stateful connection replication without problems.As shown in Figure 1, in this deployment each Cisco ACE 4.Cisco Catalyst 6.Series switch. These interfaces will be configured as a Port.Channel, as shown in Figure 2.Figure 1. Physical Deployment Figure 2.Interfaces Between Cisco ACE and Switch.The connections between the Cisco Catalyst 6.Series Switches are also important.Between each Cisco Catalyst 6.Series Switch, interface gigabit 44.Cisco ACE fault tolerant traffic only, and interfaces gigabit 44.VLANS. This configuration is shown in Figure 3.Figure 3. Interfaces Between Switches Caution This topology uses a single link for fault tolerant traffic, but it is generally a best practice to use a distributed Port.Channel multiple links spanning multiple blades to guard against physical failure.Management Topology.As shown in Figure 4, the management VLAN 9.Admin context as well as the LB0.Since this VLAN is actively shared by each Cisco ACE 4.Admin context to avoid any MAC address duplication errors between the Cisco ACE 4.Note See the Cisco ACE 4.Command Reference for more information about the shared vlan hostid command Figure 4.Management Network Topology.Fault tolerant VLAN 1.Cisco Catalyst 6.Series Switch to carry the Cisco ACE heartbeat and connection state information.This VLAN is also trunked on the Port.Channel that connects each Cisco Catalyst 6.Series Switch to the Cisco ACE 4.Logical Topology Note This Cisco ACE deployment is considered a routed deployment as opposed to a bridged or one armed deployment.As shown in Figure 5, the upstream gateway of the Cisco ACE resides in VLAN 6.The Hot Standby Router Protocol HSRP standby address is.Cisco Catalyst 6.Series Switch and.Cisco Catalyst 6.Series Switch.

Since the native VLAN is not tagged with Layer 2 information, the Qo.S Co. S values will not be set, which could lead to loss of heartbeat packets and an undesired active active outage.Recommendation Please see the Cisco ACE 4.Redundancy Guide for more information.Carrier Delay. The carrier delay command was introduced in the Cisco ACE 4.This command was added to handle a very specific scenario involving fault tolerant configurations and preemption.In this scenario, two Cisco ACE 4.LAN switch such as a Cisco Catalyst 6.Series Switch. Cisco ACE A is active, and Cisco ACE B is standby.Suppose Cisco ACE B takes over because of a failure of the Port.Channel that connects to Cisco ACE A.Moments later, the Port.Channel is restored, and Cisco ACE A comes back and wants to reclaim its active role preempt is configured by default.When Cisco ACE A comes back up, it assumes that the switch is ready to accept and process traffic.This may not be the case, however, due to timing differences.For example, the spanning tree process may still be determining whether the port can safely be put in the forwarding state on the switch side.In the meantime, the Cisco ACE 4.Address Resolution Protocol ARP information to refresh the switch fabrics MAC addresses.To prevent this timing discrepancy, you should configure a carrier delay of 3.Cisco ACE 4. 71. 0 that is configured to preempt.Note The carrier delay command is only required for deployments that use preemption.The purpose of this document is to avoid preemptive behavior.This is why the configuration references do not include the carrier delay command.This command is required on all physical interfaces Figure 1.Figure 1. 1.

CAD to CAM to CNC Part Seven Programming a CNC for 3.D Carving. My last several posts have been about how the BARN workbench vise chops were designed.In this post, Ill show you how the CNC was programmed for machining with CAM software. Bio Agent Plus Serial Crack Keygen . Cnc Part Programming Software Free Download' title='Cnc Part Programming Software Free Download' />I use Rhino.CAM software from Mec.Soft, but most CAM software programs that can handle basic 3.D milling will have similar machining operations.This post is not a primary on CAM or a full explanation of all the settings that were used just an overview of my approach to 3.D carving this project.Also, Im skipping the design, programming, and milling details of the large pocket on the backside of the vise for the Benchcrafted Criss Cross mechanism and the large through hole for the vise screw.Ill cover these processes at another time.This post is just about setting up for 3.D carving for the face of the workbench vise chops.Roll and Tuck. Roll and Tuck.The Roll and Tuck vice chop inside the 3.This vise design was one of the simplest of the set to create in CAD.The goal was to simulate roll and tuck upholstery in maple.I just created a series of semi circles and connected the ends.Once I had enough to cover the length of the vise, I extruded them to make the tuck and roll surface.Like all the other vise chops, to soften the shape, I warped the result onto the gently curved base surface and trimmed the excess.Above is the final 3.D model and how it sits inside the blank stock Im going to be milling from.Profile or Contour Cutting First.Profile or contour cutting is the CAM process used for programming a CNC to cut out parts.Essentially, its an operation to send the spindle around the perimeter of the part you want to cut out.This is a screen capture from the simulation I used to verify my programming before actual cutting.The tool paths are shown in cyan blue, the cutter is shown on the side of the vise chop.Pro tip At some point, you need to cut the part out of the blank material you start with.When I do detail 3.D carving thats right up to the edge of the piece, I sometimes machine the outside of the piece first through a process called Profile or Contour cutting.When cutting the outside of the part I leave tabs or bridges so that the cut piece is still connected to the remaining stock material.Now, that might seem a bit odd to do the last thing first, but there are good reasons to do it.If I clear off the wood thats around the outside of the final piece, unnecessary wood wont be in the way of the more delicate 3.D final carving process Ill use at the end.This is a particularly important technique when using smaller ball mills like I do for my final 3.D carving passes.Also, I run my final passes at very high speeds and yes, I have broken a few bits when they dropped down near an edge, cut too deep into the wood and snapped.Sometimes its just simpler to remove the wood that you know needs to go sooner, rather than later to eliminate potential problems.Next, Remove the Excess.A horizontal roughing pass is done layer by layer.Hard to see in this capture, but there are a dozen layers, here.Where the spindle moves from one position to the next around the chop is shown by the red lines.Similar to a 3. D topographic map, this roughing pass removes most of the material.The result is the milling looks pretty much exactly like whats shown above.With a lot of wood to remove off the surface for 3.D milling, its best to clear off as much wood as possible first.I used a roughing process that removes wood layer by layer with a.In Rhino. CAM its called Horizontal Roughing.The results are similar to a topographic map.I left about. 0. Shown above are the tool paths and a simulated carved result.Heres a short video of one of the other vise chops being rough cut on a CNCA final pass brings out the details and leaves a smooth touch.A parallel finishing pass travels the length of the design moving back and forth and up and down following the contours of the 3.D CAD design. The near side of this capture is showing the simulated final parallel run working its way through the rough cut that was done in the previous step.Now its time to CNC carve the fine details.For this particular piece, I chose to use a process called Parallel Finishing and a.This sends the cutter along the entire length of the chop, moving up and down following the roll and tuck shape.Once the spindle reaches the end of the run, it moves over a little and cuts another row and so on until its covered the entire piece.Just like moving a really large lawn, it can take quite a while.A Final Reveal. Over seven posts, weve covered the basics on how the BARN bench vise chops were designed, drawn in CAD and milled on a CNC.Now that the project is done, I have a confession Theres a reason I went into all the detail on creating these workbench vise chops.If youve patiently held on and read all the posts and seen the final results, the reason is something of a bonus.Though they turned out very nice, this was never really about vise chops.This series is really a primer on creating 3.D carved surfaces with shape and pattern in wood.If youve been reading this column regularly, its likely because youre curious about digital woodworking.The big question on everyones mind is what can be done with these tools This series answers part of that question by showing an important potential and should leave you with quite a bit to think about.If youre a furniture maker hobbyist or pro, and serious about mastering your craft and willing to really learn how to design, then digital tools are very powerful creative tools.They can take you and the pieces that you make far beyond flat surfaces into the exciting world of 3.D shaping, carving, and patterns.So, I just gave you a really big reveal.If you want to take that next big step forward in furniture design heres the secret Combine the traditional woodworking craftsmanship we all love with digital woodworking tools and good design skills.Its a killer combo that takes furniture making into exciting new directions.Stay tuned. Also, a note that Im teaching a hands on class on these and other intermediate and advanced techniques at the Marc Adams School of Woodworking in Indiana on October 1st.Good choice if youve already started using CAD and ready to get moving on getting the best out of a CNC.The class is about digital woodworking skills and techniques in CAD, CAM, and CNCs and using these new tools along side traditional woodworking methods.A few openings are left.Finally, regarding the BARN Workbench, Ill do a future post on how the dogs holes on the top of workbench were laid out in a way to make traditional hand tool woodworking a bit more comfortable to do.Told you that using a CNC to make a hand tool workbench is a little different.And, a post showing the final 9 workbenches in their new home.Tim Celeski.

Upon verifying that the fields are correct, click the Restore button and select Erase from the application, if prompted to do so.Figure F. 1. 2. The process may indicate in excess of one hour, but in my experience the process takes significantly less time to complete.Figure G.

Upon verifying that the fields are correct, click the Restore button.Select Erase from the confirmation box, if prompted to do so.If asked to authenticate, enter credentials that have administrator access and click OK to proceed.Since this scenario requires reading data from the optical drive, it may perform slower than reading files that are located on the hard drive.Once completed, the USB drive will be bootable and have the full installation of OS X on there to install from scratch and update systems, as needed.Remember, this being a writable drive offers some additional perks over read only media with a few caveats as well.Pros. Include additional resources on the drive that are required by your organization, such as Combo Updaters, applications or settings.Backup directories prior to initializing the HDD andor reinstalling OS X.Include multiple versions of OS X on the same drive.Cons. Writable means live data can be subject to accidental deletion or corruption.ReadWrite speeds vary wildly depending on the makemodel of the USB drive.Choose the highest read and write speeds for your particular application to minimize this bottleneck.Losstheft of USB drives and any additional data, such as configurations, passwords, etc.Be carefulNote Feel free to include any additional files or folders to the existing drives, so long as the original file hierarchy is not modified in any way.This is important as the OS X installer is looking for specific files at specific locations during installation.A missing, modified or corrupt file could result in an unreliable installation.Multiple OS X versions on the same USBSD card BonusWhile writing this article, I found myself in a predicament I only had a 8.GB USB drive But luckily, I found a 1.GB drive Id lent my wife awhile back and decided to try to get the two versions of OS X encountered most frequently 1.GB USB drive. And it worked To achieve this, youll want to have a USBSD card capable of holding all the OSs on drive.This means about 8.GB of storage space per version of OS X.The steps are identical to the Creating a USB Installer for Apple OS X 1.Instead of selecting 1 partition in step 4, youll be selecting a number equal to the number of versions of OS X youll be copying over.Ex. If housing 1.GB x 4 versions of OS X 3.GB total 4 partitions will then need to be created.The copying process steps 9 1.OS X being stored.Tip By default, Disk Utility names the partition identical to the source Mac OS X Install DVD in my case. Green Dot Card Not Activated Windows . While thoughtful, if working with multiple partitions, each will have the same name making them indistinguishable from the others.To resolve this, once the entire copy process has completed for all versions of OS X, the Finder will mount them all on the Desktop.Go through each to identify which version of OS X is contained, then simply rename it to a common name, such as 1.Lion installer 1.Mountain Lion, etc.When booting to the USBSD card by holding the Option key during start up, the drives will mount with their new names making them easier to identify. |
