Please see the below. Thank you. Current configuration : 52 bytes! Thank you for your reply. These ports are not connected with TFTP server. I used the command, but it did not show the difference. I meant that config file was obtained from TFTP server not this interface needs to be connected to the tftp server. If we change anything on that interface, that will show as manual and after write memory and reload. The method field has the following possible values:.

Created by Mohamed Alhenawy on AM.Upgrading software on Cisco Catalyst switches isn't necessarily difficult to do, but it can be a time-consuming process.

This is made even more apparent when a large quantity of switches needs to be upgraded for a project. IOS software image size has certainly increased over time. Newer switches, such as the Catalystuse an extremely large software image because they support so many features. For example, version Sitting and staring at the console as a TFTP file transfer occurs for an image of this size is nothing short of painful.

Most of the time, we will use TFTP to copy a new version of software to a switch. This is the lowest possible value, and this is used to ensure compatibility with older TFTP servers. Last week, we had to upgrade software on several Catalyst switches, so we performed one upgrade with this default block size setting of to illustrate what we're talking about. OK, let's do some quick math. As you can see in the above graphic, this MB file took 2, seconds to transfer.

So, 2, seconds divided by 60 equals 43 minutes. The truth is that most TFTP servers can accommodate a much larger block size than The maximum size that this Catalyst can support is a block size of So whenever we perform a file transfer, we first enter this command in global config mode on the switch:.

Once we entered that command, we performed the file transfer in the exact same method as before. But here are the results when using the maximum block size:.

That same MB file took seconds to transfer this time. If we divide seconds by 60 we get 5 minutes. This command will also work on most other modern Catalyst switch models, such as the X, X, chassis, C, etc. Did this tip work for you? What IT professional has the time to wait 43 minutes for a software upgrade?

So whenever we perform a file transfer, we first enter this command in global config mode on the switch: ip tftp blocksize Once we entered that command, we performed the file transfer in the exact same method as before.

The only question now is what will you do with all that time saved?Routers often get upgraded or swapped out for a number of reasons. This document provides the user with some basic steps to migrate the configuration from an existing router to a new router.

Use the ping command to verify connectivity. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared default configuration. If your network is live, make sure that you understand the potential impact of any command. Refer to Cisco Technical Tips Conventions for more information on document conventions.

This is a step-by-step approach to copy a configuration from a router to a TFTP server, and back to another router. Before you proceed with this method, make sure you have a TFTP server on the network to which you have IP connectivity.

The prompt changes to Routerwhich indicates that the router is now in privileged mode. Open the configuration file with a text editor. Search for and remove any line that starts with "AAA". Copy the configuration file from the TFTP server to a new router in privileged enable mode which has a basic configuration. Copy the configuration file from the FTP server to a router in privileged enable mode which has a basic configuration.

A terminal emualation program can be used to back up and restore a configuration. This is a description of the procedure using Microsoft Hyperterminal Terminal Emulation software:. If the configuration needs to be copied from another router, connect to that router through the console or Telnet. Issue the terminal length 0 command in order to force the router to return the entire response at once, rather than one screen at a time. This allows you to capture the configuration without extraneous --more-- prompts generated when the router responds one screen at a time.

Issue the show running-config command, and allow time for the router to complete its response. You will see:. You can do this by dragging the cursor from before the first character to after the last character in the file while holding down the left mouse button.

Switch to the HyperTerminal window, and issue the configure terminal command at the Router prompt.

Then press Enter. After the configuration has finished pasting and the router brings you back to the configuration prompt, issue the copy running-config startup-config command in order to write the configuration into memory. In order to get a router to copy the running-config to startup-config, for example every Sunday atcomplete these steps:. Create a kron policy list —This is the script that lists what commands the router should run at the scheduled time.

It is important to remember this when you create commands. Also, note that kron does not support configuration commands.

Create a kron occurrence —This informs the router when and how often the policy should run. SaveConfigSchedule —This is the name of occurrence.

Length of occurrence-name is from 1 to 31 characters. If the occurrence-name is new, an occurrence structure will be created. If the occurrence-name is not new, the existing occurrence will be edited. Use the show running-config command to confirm that the configuration file has been copied to the destination router.This appendix describes how to manipulate the Catalyst X or X switch flash file system, how to copy configuration files, and how to archive upload and download software images to a Catalyst X or X switch or to a Catalyst X switch stack.

Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack. Note For complete syntax and usage information for the commands used in this chapter, see the switch command reference for this release and the Cisco IOS Configuration Fundamentals Command Reference, Release The flash file system is a single flash device on which you can store files. It also provides several commands to help you manage software image and configuration files.

tftp cisco 3560

The default flash file system on the switch is named flash:. As viewed from the stack master, or any stack member, flash: refers to the local flash device, which is the device attached to the same switch on which the file system is being viewed.

In a switch stack, each of the flash devices from the various stack members can be viewed from the stack master. The names of these flash file systems include the corresponding switch member numbers. For example, flash3:as viewed from the stack master, refers to the same file system as does flash: on stack member 3.

Use the show file systems privileged EXEC command to list all file systems, including the flash file systems in the switch stack. No more than one user at a time can manage the software images and configuration files for a switch stack. These sections contain this configuration information:.

To display the available file systems on your switch, use the show file systems privileged EXEC command as shown in this example for a standalone switch. This example shows a switch stack.

In this example, the stack master is stack member 2; therefore flash2: is aliased to flash:. The file system on stack member 5 is displayed as flash5 on the stack master. Amount of free memory in the file system in bytes. You can copy a remote file to null to find its size. You can specify the file system or directory that the system uses as the default file system by using the cd filesystem: privileged EXEC command.

You can set the default file system to omit the filesystem: argument from related commands. For example, for all privileged EXEC commands that have the optional filesystem: argument, the system uses the file system specified by the cd command. By default, the default file system is flash:. You can display the current default file system as specified by the cd command by using the pwd privileged EXEC command.I would like to show you how to recover a Cisco switch ex.

Here what I think is incorrect in the documentation and else where they copy pasted the instructions without verifying it. So follow the steps below if you are also trying to recover the switch from boot load using TFTP to transfer file. If you like to use USB flash drive to transfer image to the flash click here. Make sure the variable are set in the same format below. Note: After flash: you need to specify full file name or else it will not accept. The steps as as below.

I hope I have covered every step here. Please leave a comment and let me know if there is anything you feel is incorrect and if this have helped you or not. Please also look at this blog post.

SE5 flash:clanbasek9-mz. SE5: no such device. SE5 gateway is my laptop IP address Am trying to use Transfer will start, but is going to take a lot of time.

Issue the show version command in order to verify the file, if is OK, proceed to next step otherwise retry transfer. If the set BAUD command does not bring the baud rate toissue the unset BAUD command in order to bring the baud rate to a default value of bps.

I made a mistake and deleted flash. I have a backup … how to flash back Help. God bless you man, I accidentally hosed my companies switch while on loan.Fundamentally it provides the area to execute commands to configure and administer the device. Cisco may release different version and different feature set IOS image for same platform hardwareso you may have to upgrade existing IOS to new IOS supporting advanced features and facilities.

Once you have the basic idea regarding IOS naming, you may decide whether the upgrade is needed or which version you need to go and upgrade and so on. Cisco vends multiple variants of IOS software for routers and switches. Cisco provides two major commands to check IOS version and related information includes model number, types of interfaces, amount of memory, software version, and configuration setting.

Let me give you a screenshot of my production router running right here. Following screenshot shows flash content of my production router sitting besides me.

Cisco routers are available in different series, a series is Platform or hardware architecture where IOS will run.

Those are given in the following table. Type refers compression and IOS image run location. It should be decompressed before running. This 3 character designates digitally signed Cisco IOS software. These file extensions are:. This is the version number of IOS software image. Represents additional release Extended Maintenance which supports some extra capabilities.

T provides a comprehensive portfolio of over abilities, including the leading-edge functionality and hardware support Standard Maintenance. Let me fly-back through the naming with simple memorable representation, cuniversalk9-mz.

What a fantastic nomenclature has been done by Cisco! You may download it from the following link. Step 3: Enter to privilege mode and issue the commands. Now check the flash content again, there will be 2 images cadvipservicesk9-mz. Delete the old IOS file using delete command, then reload router.

I do recommend that you make sure there is a non-DOA guarantee on the gear, so that you have recourse if it shows up dead. Hopefully it comes with the IOS already resident as well.

As long as you are in possession of the IOS, you are in good shape. If you already own the device, it would be the sensible thing to copy off the IOS just in case your existing copy somehow gets corrupted. Now to get the IOS back onto the device. There are many articles on the web dealing with this process so I am not really divulging any never-before-seen secrets.

However, I would like to show how the steps look as we go through the process for those who truly have never done it before. You will need a terminal emulator with which to view the Cisco device output. Baud rate : bits per second Data bits : 8 Parity : none Stop bits : 1 Flow control : none.

If the router boots directly into rommon, it is quite likely that there is no IOS file in flash. You can issue the dir flash : command from within rommon to verify this. If you do not see a file named xxxxx.

Verify that it is installed and running and reachable over the network by the router. If you have created a backup copy of the Cisco IOS as noted above, you are ready to proceed with these steps.

tftp cisco 3560

If not, you will need to find another way to obtain the IOS. If these steps are being taken within a corporate environment, it is likely a SmartNet or some type of support agreement exists between your organization and Cisco. If that is the case, Cisco provides the IOS files at their website for registered customers. This will give you a rundown of the current values for the pieces that matter to us for these steps.

Here are the relevant values: These statements are case-sensitive!
