Techroute Switch Configuration Guide

One of the great advantages of router and switch configuration is you can increase security in several ways. The most basic thing you can do is change the router password from its default to something more secure and unique. This prevents hackers from accessing your router settings. Via the router, a hacker could potentially disable wireless security for your network, meaning they could access sensitive or confidential business data without you ever knowing about it.
You can also configure router settings to disguise your local IP address. You can change your IP address by tweaking your settings. The most common reason for doing this is to protect your anonymity online, making it harder for your activity to be traced back to you. This is another useful security benefit, although not necessarily a top priority for business purposes.
Switches can be used to connect numerous devices together on the same network. Local area network (LAN) switches are used for controlling and directing the data flow to networked resources, at the level of the access layer. A switch is sometimes referred to as a network bridge.
A major cause of network downtime is human error. With Network Configuration Manager, you can automate processes and gain visibility to better avoid manual configuration errors potentially leading to network interruptions. You can set permissions and roles to ensure the right users are making configuration changes. And you can get instant insight into configuration changes, so you always know what changes occurred and who made the change. You can even search, troubleshoot, and audit standardized configurations.
A powerful network automation and configuration management tool built to support small business networks, Kiwi is an affordable solution for companies of all sizes looking for the ability to more easily push configuration changes, track changes on network devices with alerts, revert to previous configurations, perform basic config change reporting, and automate backups on routers, switches, and firewalls.
Kiwi CatTools has out-of-the-box support for a lot of IPv4 and IPv6 devices, such as Cisco, HP, Huawei, Juniper, and more. Kiwi supports your ability to more easily troubleshoot issues by allowing you to compare the configurations of two devices, like startup and running configurations, to help ensure the success of your network. Using a built-in TFTP server, Kiwi can also provide an easier way to push configuration changes on multiple devices at the same time. You can also try the tool for yourself free for 14 days.
BPDU's are used Spanning-tree, and while there is more to be explained than that, the easiest way is to point you to the section of cisco's site that covers the configuration, explanation of and adminitration of spanning-tree, and its uses.
There is one "master" MAC address for the switch, known as the Bridge ID. You can see that be doing a show spanning-tree and looking for the "Bridge ID" (not necessarily the Root ID).
If you do a show mac-address-table, those are not the MAC addresses of your switch, but the MAC addresses of the things attached to your switch, together with the ports they are attached to.
Not all switches will tell you the base MAC address for a show version. For example, my 4500s do not, but my 3560s do so. And in my 3560s, yes, the MAC address shown in show version is the same as the Bridge ID shown in show spanning-tree.
In some troubleshooting scenarios, you may need to view the switch configuration to diagnose a problem. The complete switch configuration is contained in a file that you can browse from the CLI using the commands described in this section.
When you enter the show tech command, a summary of switch operational data is sent to your terminal emulator. You can use your terminal emulator's text capture features to save the show tech data to a text file for viewing, printing, or sending to an associate to diagnose a problem.
For example, if your terminal emulator is the Hyperterminal application available with Microsoft Windows software, you can copy the show tech output to a file and then use either Microsoft Word or Notepad to display the data. (In this case, Microsoft Word provides the data in an easier-to-read format.)
The show tech command output is copied into the text file and displayed on the terminal emulator screen. When the command output stops and displays -- MORE --, press the Space bar to display and copy more information. The CLI prompt appears when the command output finishes.
Specifies the operational and configuration data from one or more source files to be displayed by the show tech command. Enter the command once for each data file that you want to include in the display.
Displays the software version currently running on the switch and the flash image from which the switch booted (primary or secondary). For more information, see "Displaying Management Information" in the "Redundancy (Switch 8212zl)" chapter.
Displays the same information as the show interfaces command and dynamically updates the output every three seconds. Press Ctrl + C to stop the dynamic updates of system information. Use the Arrow keys to view information that is off the screen.
Uses matching pattern searches to display selected portions of the output from a show command. There is no limit to the number of characters that can be matched. Only regular expressions are permitted; symbols such as the asterisk cannot be substituted to perform more general matching.
The show arp command and pattern matching with the include option is an Example: of the show arp command output, and then the output displayed when the include option has the IP address of 15.255.128.1 as the regular expression.
Watch the videos and then work through each tab. I have created a custom gcode generator to assist in making testing towers. This used to be a laborious process and beyond the skills of many users. Other times pre-sliced gcode was used from the internet, but it is impossible to have gcode available for every printer configuration. Until now!
Every attempt has been made to ensure this is safe but ultimately there always is risk in running pre-sliced gcode from the internet. Preview the gcode in your slicer or Zupfe GCode Viewer and print at your own risk.
The gcode generated by this page is originally from Simplify3D. This website then uses Javascript to modify the contents based on user inputs. This site is not a web based slicer, therefore it is limited in some ways.
The aim for the site is to provide compatibility with the majority of 3D printers. It aims to be beginner friendly and as such where possible the interface is kept as minimal as possible. Because of this, some requests for extra functionality will not be accepted. Something that makes the experience better for 1% of users but confuses 40% of others is not worth including.
A 'calibration' slicer profile in S3D is used as the basis of the gcode on this site. S3D offers multiple processes to assist with splitting the towers into segments where the print settings can vary. Apart from this, the only special functionality used is post processing scripts to delete some lines, and to modify others with simple search and replace functions.
You may notice settings related to temperatures, retraction, Z hop, part cooling, etc have set values, but these are altered by post processing scripts and this site to ultimately be set using the user's inputs. Several parameters work like this, please don't be fooled by what is in the slicing profile. Opening the final gcode file in a text editor and searching for 'custom' will show if the user's inputs have been successfully adopted.
The information below is mainly for my reference. However, if you wish to duplicate the tests yourself out of interest or perhaps to develop a new test for the site, then the steps must be followed exactly, including replicating the process names.
First layer test: No changes, although it should be noted that a single square is included which is then duplicated and positioned by this site. Non uniform scaling of the source STL needs to occur to suit certain nozzle/layer combinations. The square should be 25 x 25 mm with it's height scaled to match the target layer height.
If your printer has a motion system based on V-roller wheels riding on V-slot extrusions, check they are properly tensioned. Each location will have one eccentric nut. This can be twisted to either add or remove tension on the wheels.
Lubrication is an important maintenance task to perform regularly. Components that are not adequately lubricated may bind and affect print quality. Use SuperLube Synthetic Grease. Lubrication needs to be performed regularly on any hardened rods, linear rails and lead screws.
Probably the most essential part of setting up your 3D printer. Most new users will trip up on this. If you have ABL, this includes making sure your Z offset has been set and saved. Dialing in the first layer has now been moved to its own tab.
If your printer has PTFE tube, such as a bowden tube setup for the extruder/hot end, it is essential to make the tube is fully inserted and seated in the coupler. Also ensure the coupler is properly tightened. You may wish to use a small retaining clip on the coupler to prevent the tube working loose: Creality PTFE clip by morfidesign.
It is worth heating up the nozzle and pushing some filament through to see if it is exiting the nozzle properly. If the diameter is inconsistent or the extruded plastic shoots to one side, it may indicate a partial blockage in the nozzle that will be a pain in the future. It is also worth checking if the nozzle is properly tightened. Only do this when it is hot, or you may break it.
Check all fans are spinning freely. This includes but is not limited to: mainboard cooling fan, heat sink fan, part cooling fan, PSU fan. It can be hard to diagose if a fan is performing at less than full capacity. It may be easier to simply replace than repair if you suspect a fan is failing.
