Cisco router downloads hang

Using an external repository provides a central common repostiory to be used across devices. This eliminates the need to copy files for future updates to each router individually.

It also serves as a single source when new RPMs bug fixes, packages, updates are made available. This is the recommended method to setup a repository. For release 7.

For releases 7. If a VRF has more than one loopback interface, the loopback with the lowest-numbered loopback name is selected. For example, Loopback1 is selected over Loopback2.

Ensure that the server is reachable as specified in the note above. Install createrepo utility on the Linux distribution system if not installed already. Create a directory on the server and copy all the RPMs to a directory.

If the RPM files are archived. The files hierarchically arrange in sub directories under the main directory that is used as a repository. Convert the directory to a repository using createrepo utility on the Linux server. This creates a directory named repodata with the metadata of all the RPMs. If you add new packages to the repository, change or remove packages from the repository, you must run createrepo command again to update the metadata. This ensures that the package manager chooses the correct packages.

The contents of the repository are displayed only when the configured repository is valid and the RPMs with the updated metadata are present in the repository. You can upgrade the system when a newer version is available. A system upgrade replaces the existing version of the software with a newer version. By keeping the software up-to-date, you can ensure that the device works with the latest features and bug fixes.

Only a minimal set of changes is performed to upgrade to the new software. Packages are not removed and reinstalled if they have the same name and version. For example, an upgrade that differs by only one package will only remove and install that one modified package.

When first moving the system to release 7. Upgrades from release 7. This section shows replacing the current software version with x To understand the phases of install operation, see Software Deliverables and Terminologies.

GISO is a customized image with the standard functional components and additional configuration files. This feature introduces iso-config [ignore replace] keywords to the install replace and install package replace commands. This feature enables an automated check during install [package] replace operations to ensure that the GISO image has not been corrupted. It does so by calculating the md5sum of the GISO and comparing it against an md5sum contained within the GISO that was calculated when the image was built.

The ZTP configuration is applied on the router when the current software version is replaced or rolled back to a version with GISO image and is used whenever ZTP is run to automatically provision the router. A reboot is not always necessary. Bugfixes can be applied using a GISO that contains the current running software and the additional bugfix. These fixes may not require a reboot. Reboots are required for a system version change, if too many processes need restarting, there is configuration in the GISO to apply or if the bugfix is marked as requiring a reload.

The ztp. If the. For example, if the install starts a reload operation or when ZTP is initiated manually, the ZTP will run with the custom ini. This file is carried over during install replace and install rollback, as long as both the from-version and the to-version are Cisco IOS XR, Release 7. If you start an install replace or install package replace operation with a GISO that has a ztp. If you replace the image using an ISO without a ztp.

Prior to this release, the configuration file in GISO is ignored by default. If the GISO has a configuration file and it is not ignored using the iso-config ignore option then the configuration in the file is applied, and the install operation requires a reboot. With the iso-config keyword, the default value is set to replace to replace the running configuration with the configuration in the file. You can extract the configuration file from GISO using image.

The extracted configuration file replaces the running configuration after the router reloads. Extracts the configuration and replaces the running configuration after the changes are applied via router reload. Does not extract or apply the configuration. The output of the show install log command does not display any information related to the configuration. The behavior is similar to iso-config replace operation. Attempts extracting the configuration, and the operation continues as if configuration is not requested.

Attempts extracting the configuration. Upgrade the system to replace the current software with the x The md5sum of the GISO is checked automatically during this operation to ensure that the image has not been corrupted. If you are using a configuration file in GISO, use the install apply reload command for the configuration to take effect. To identify whether a reload is required or only process restart is needed, use either show install history last transaction verbose command or show install request command.

Include the keyword noprompt in the command to enable the system to bypass your permission to reload the router. Applying the change gives you the flexibility to test the operation of the new software before committing the changes. If you reload the router, the router reverts the software to its previous software state. All operations that automatically apply the new software are prohibited when an atomic change is already in progress.

You must address the current atomic-change before performing this operation. To address the change, apply the current atomic-change, or abort it with the install package abort all-since-apply command.

Configure a repository on the router. The operation ID is a unique ID for each user request. Did you mean:. All Community This category This board.

Resolution Whenever you install a new card, module or Cisco IOS Software image, verify that the router has enough memory and that the hardware and software are compatible with the features you are using.

To check for hardware and software compatibility and memory requirements, perform these steps: Choose the software for your network device by referring to Software Advisor. Perform these steps: Verify whether the modules and cards installed on the router are supported by the desired Cisco IOS Software version.

Determine the Cisco IOS Software image that you need and choose the types of features that you will implement by referring to the Compare the features in different software releases section of Software Advisor.

Choose from one of these options: If you want to keep the same features as the version currently running on your router, but do not know which feature set you are using, issue the show version command on your router and paste the output into the Output Interpreter tool.

If you plan to use recent software features, check for feature support. Tags: Latest Contents. Created by dkafrissen on AM. HiI rarely work on our Nexus series switches, I've been here four years and with the panini I haven't touched them in two years by the Config backup date at least.

Anyway, my boss wants to try to use one of our Storage array as an SMB and woul Created by alemulde on AM. As a workaround to this problem, boot the router into ROMMON, and bypass the stored configuration, and then configure it again. Complete these steps:. Change the configuration register to 0x and then reset the router. This causes the router to boot from Flash without loading the configuration. Now, you can save an empty configuration all commands removed.

Issue the copy running-config startup-config command. Alternatively, if you suspect that a certain command causes the problem, you can edit the configuration. To do so, issue the copy startup-config running-config command. Then type configure terminal , and make the changes. When finished, change the configuration-register back to 0x For this, type config-register 0x Issue the copy running-config startup-config command to commit the changes.

If traffic no longer passes through the router and the console is unresponsive, there is probably a problem with the system. Generally this means that the router is caught in a continuous loop or stuck at a function.

This is almost always caused by a bug in the software. Install the most recent maintenance release of the Cisco IOS software train you currently run. Obtaining stack traces during a problem makes it possible to determine where in the code the router is looping or stuck.

Traffic problems occur when the console remains responsive but traffic does not pass through the router. In this case, part of the traffic or part of the interfaces are not responsive. This behavior can be caused by a variety of different causes. When this problem occurs, information can be collected from the router through the console port. The causes for these traffic problems can range from errors on the interfaces to software and hardware problems.

Routing issue — Changes in the network topology or in the configuration of some routers could have affected the routing tables. Interface down — One of the router interfaces can be down. There are multiple events that could cause this, which can range from a wrong configuration command to a hardware failure of the interface or the cable.

If some interfaces appear down when you issue a show interfaces command, try to find out what caused it. Wedged interfaces — This is a particular case of buffer leaks that causes the input queue of an interface to fill up to the point where it can no longer accept packets.
