Cisco 2960 ios 12.2(55) download

Software images located on a server or downloaded from Cisco. This example shows some of the information contained in the info file. Table provides additional details about this information:. It does not apply to the switch. Table info File Description.

Specifies the Cisco IOS image version string suffix. Specifies the name of the Cisco IOS image within the tar file. Specifies the Cisco IOS image size in the tar file, which is an approximate measure of how much flash memory is required to hold just the Cisco IOS image. Specifies the size of all the images the Cisco IOS image and the web management files in the tar file, which is an approximate measure of how much flash memory is required to hold them. Specifies the minimum amount of DRAM needed to run this image.

Describes the family of products on which the software can be installed. You download a switch image file from a server to upgrade the switch software. You can overwrite the current image with the new one or keep the current image after a download. You upload a switch image file to a server for backup purposes; this uploaded image can be used for future downloads to the same or another switch of the same type.

To upgrade a switch with an incompatible software image, use the archive copy-sw privileged EXEC command to copy the software image from an existing stack member to the incompatible switch.

Before you begin downloading or uploading an image file by using TFTP, do these tasks:. You can download a new image file and replace the current image or keep the current image. To keep the current image, go to Step 3. Copy the image to the appropriate TFTP directory on the workstation.

Download the image file from the TFTP server to the switch, and overwrite the current image. Download the image file from the TFTP server to the switch, and keep the current image. The download algorithm verifies that the image is appropriate for the switch model and that enough DRAM is present, or it aborts the process and reports an error. If there is not enough space to install the new image and keep the running image, the download process stops, and an error message is displayed.

The algorithm installs the downloaded image on the system board flash device flash:. The image is placed into a new directory named with the software version string, and the BOOT environment variable is updated to point to the newly installed image. For file-url , enter the directory name of the old image. You can upload an image from the switch to a TFTP server. You can later download this image to the switch or to another switch of the same type.

Use the upload feature only if the web management pages associated with the embedded device manager have been installed with the existing image.

Upload the currently running switch image to the TFTP server. The archive upload-sw privileged EXEC command builds an image file on the server by uploading these files in order: info, the Cisco IOS image, and the web management files. After these files are uploaded, the upload algorithm creates the tar file format. You upload a switch image file to a server for backup purposes.

You can use this uploaded image for future downloads to the switch or another switch of the same type. You can copy images files to or from an FTP server. When you copy an image file from the switch to a server by using FTP, the Cisco IOS software sends the first valid username in this list:. If you are writing to the server, the FTP server must be properly configured to accept the FTP write request from you. Include the username in the archive download-sw or archive upload-sw privileged EXEC command if you want to specify a username only for that operation.

If the server has a directory structure, the image file is written to or copied from the directory associated with the username on the server. For example, if the image file resides in the home directory of a user on the server, specify that user's name as the remote username. Before you begin downloading or uploading an image file by using FTP, do these tasks:.

You can download a new image file and overwrite the current image or keep the current image. To keep the current image, go to Step 7. Download the image file from the FTP server to the switch, and overwrite the current image. Download the image file from the FTP server to the switch, and keep the current image. The algorithm installs the downloaded image onto the system board flash device flash:.

For file-url , enter the directory name of the old software image. You can upload an image from the switch to an FTP server. You can later download this image to the same switch or to another switch of the same type. Upload the currently running switch image to the FTP server. The archive upload-sw command builds an image file on the server by uploading these files in order: info, the Cisco IOS image, and the web management files. You can use this uploaded image for future downloads to the same switch or another of the same type.

RCP provides another method of downloading and uploading image files between remote hosts and the switch. For the RCP copy request to execute successfully, an account must be defined on the network server for the remote username. If the server has a directory structure, the image file is written to or copied from the directory associated with the remote username on the server.

Before you begin downloading or uploading an image file by using RCP, do these tasks:. For example, suppose the switch contains these configuration lines:. You can download a new image file and replace or keep the current image. To keep the current image, go to Step 6. Download the image file from the RCP server to the switch, and overwrite the current image. Download the image file from the RCP server to the switch, and keep the current image.

If there is not enough room to install the new image an keep the running image, the download process stops, and an error message is displayed. You can upload an image from the switch to an RCP server.

The upload feature should be used only if the web management pages associated with the embedded device manager have been installed with the existing image. Upload the currently running switch image to the RCP server. For switch stacks, the archive download-sw and archive upload-sw privileged EXEC commands can be used only through the stack master. To upgrade a switch that has an incompatible software image, use the archive copy-sw privileged EXEC command to copy the software image from an existing stack member to the one that has incompatible software.

Note To successfully use the archive copy-sw privileged EXEC command, you must have downloaded from a TFTP server the images for both the stack member switch being added and the stack master. You use the archive download-sw privileged EXEC command to perform the download. Beginning in privileged EXEC mode from the stack member that you want to upgrade, follow these steps to copy the running image file from the flash memory of a different stack member:. Copy the running image file from a stack member, and then unconditionally reload the updated stack member.

Note At least one stack member must be running the image that is to be copied to the switch that is running the incompatible software. If you do not specify this stack member number, the default is to copy the running image file to all stack members.

For source-stack-member-number , specify the number of the stack member the source from which to copy the running image file. The stack member number range is 1 to 9. Reset the updated stack member, and put this configuration change into effect. Skip to content Skip to search Skip to footer. Book Contents Book Contents. Find Matches in This Book.

PDF - Complete Book Updated: October 17, Working with the Cisco IOS File System, Configuration Files, and Software Images This appendix describes how to manipulate the Catalyst and switch flash file system, how to copy configuration files, and how to archive upload and download software images to a switch. Free b Amount of free memory in the file system in bytes. Type Type of file system.

Flags Permission for file system. Prefixes Alias for file system. Setting the Default File System 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. Displaying Information about Files on a File System You can view a list of the contents of a file system before manipulating its contents. Changing Directories and Displaying the Working Directory Beginning in privileged EXEC mode, follow these steps to change directories and display the working directory.

Command Purpose Step 1 dir filesystem : Display the directories on the specified file system. Step 3 pwd Display the working directory. Creating and Removing Directories Beginning in privileged EXEC mode, follow these steps to create and remove a directory: Command Purpose Step 1 dir filesystem : Display the directories on the specified file system.

Directory names are case sensitive. Step 3 dir filesystem : Verify your entry. Caution When files and directories are deleted, their contents cannot be recovered. Copying Files To copy a file from a source to a destination, use the copy source-url destination-url privileged EXEC command. Deleting Files When you no longer need a file on a flash memory device, you can permanently delete it. Caution When files are deleted, their contents cannot be recovered. This example shows how to delete the file myconfig from the default flash memory device: Switch delete myconfig Creating, Displaying, and Extracting tar Files You can create a tar file and write files into it, list the files in a tar file, and extract the files from a tar file as described in the next sections.

Saved configuration on server! You might want to perform this for one of these reasons: To restore a backed-up configuration file. To use the configuration file for another switch. For example, you might add another switch to your network and want it to have a configuration similar to the original switch.

By copying the file to the new switch, you can change the relevant parts rather than recreating the whole file. To load the same configuration commands on all the switches in your network so that all the switches have similar configurations. Use these guidelines when creating a configuration file: We recommend that you connect through the console port for the initial configuration of the switch.

If you are accessing the switch through a network connection instead of through a direct connection to the console port, keep in mind that some configuration changes such as changing the switch IP address or disabling ports can cause a loss of connectivity to the switch.

If no password has been set on the switch, we recommend that you set one by using the enable secret secret-password global configuration command. Configuration File Types and Location n Startup configuration files are used during system startup to configure the software.

Creating a Configuration File By Using a Text Editor When creating a configuration file, you must list commands logically so that the system can respond appropriately. This is one method of creating a configuration file: Step 1 Copy an existing configuration from a switch to a server. Search instead for. Did you mean:. All Community This category This board. Thank you for your time. Labels: Labels: Other Switching. I have this problem too. All forum topics Previous Topic Next Topic.

Leo Laohoo. VIP Community Legend. How was the switch upgraded? Was it by copying the BIN file into the switch? In response to Leo Laohoo. Hi, What browser are you using? These are known limitations that will not be fixed, and there is not always a workaround. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.

This problem occurs under these conditions:. The workaround is to reconfigure the static IP address. The workaround is to enter the no switchport block unicast interface configuration command on that specific interface. There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. The workaround is to configure aggressive UDLD. The workaround is to always enter a nonzero value for the timeout value when you enter the boot host retry timeout timeout-value command.

If this happens, uneven traffic distribution occurs on EtherChannel ports. Changing the load balance distribution method or changing the number of ports in the EtherChannel can resolve this problem.

Use any of these workarounds to improve EtherChannel load balancing:. For example, with load balance configured as dst-ip with distinct incrementing destination IP addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is optimal. The workaround is to enable PoE and to configure the switch to recover from the PoE error-disabled state.

The workaround is to reduce the number of multicast routes and IGMP snooping groups to less than the maximum supported value. The switchport block multicast interface configuration command is only applicable to non-IP multicast traffic. The workaround is to enter the clear ip mroute privileged EXEC command on the interface. After you configure a switch to join a multicast group by entering the ip igmp join-group group-address interface configuration command, the switch does not receive join packets from the client, and the switch port connected to the client is removed from the IGMP snooping forwarding table.

The workaround is to enter the shutdown and the no shutdown interface configuration commands on the Fast Ethernet interface of a new IP phone that is attached to the service module port after the internal link is brought up. The workaround is to reduce the number of VLANs or trunks. The workaround is to enter the switchport access vlan dynamic interface configuration command separately on each port. The workaround is to click Yes when you are prompted to accept the certificate.

If this message appears, check that there is network connectivity between the switch and the ACS. From the Settings window, choose Automatically. Click OK to exit the Internet Options window. Configure the HTTP server interface for the type of authentication that you want to use. You should write down the port number through which you are connected. Use care when changing the switch IP information. If you are not using the default method of authentication the enable password , you need to configure the HTTP server interface with the method of authentication used on the switch.

In a Smart Install network, when the director is connected between the client and the DHCP server and the server has options configured for image and configuration, the client does not receive the image and configuration files sent by the DHCP server during an automatic upgrade. Instead, the files are overwritten by the director, and the client receives the image and configuration that the director sends.

For clients to upgrade using Smart Install, you should configure product-id specific image and configuration files in the director. When you add a static EnergyWise neighbor to a Catalyst C switch, a traceback error could occur or the switch could reload under these circumstances:. The problem can occur when you enter the energywise neighbo r [ hostname ip-address ] udp-port-number global configuration command on the Catalyst C to try to add the third switch as an EnergyWise neighbor.

The workaround is to establish the route by pinging the EnergyWise switch before you enter the energywise neighbor command. On occasion, the issue does not self-correct, and the ports might remain unbundled. The workaround is to reload the switch or to restore the EtherChannel bundle by shutting down and then enabling the member ports and the EtherChannel in this order:.

The problem is visible only when you stop the auto-boot process to access the bootloader. Although you can apply the LAN base routing template to the switch, you cannot use the ip routing global configuration command.

A vulnerability exists in the Smart Install feature of Cisco Catalyst Switches running Cisco IOS Software that could allow an unauthenticated, remote attacker to perform remote code execution on the affected device. Cisco has released free software updates that address this vulnerability. There are no workarounds available to mitigate this vulnerability other than disabling the Smart Install feature.

The switch can also receive power from an AC power source when you use the auxiliary power input. When both uplink ports and auxiliary power are connected, the auxiliary power input takes precedence. The Catalyst CPD-8PT switch can provide power to end devices through the eight downlink ports in one of two ways:.

The downlink ports are PoE-capable, and each port can supply up to When the switch draws power from the uplink ports, the power budget the available power on downlink ports depends on the power source options shown in Table 5.

When the switch receives power through the auxiliary connector, the power budget is similar to that of any other PoE switch. You can configure the power management, budgeting, and policing the same as with any other Catalyst or S PoE switch. The show env power inline privileged EXEC command provides information about powering options and power backup on your switch:. You can see the available power and the power required by each connected device by entering the show power inline privileged EXEC command.

Enter the show power inline police privileged EXEC command to see power monitoring status. The show power inline dynamic-priority command shows the power priority of each port:. Because of the compact size of the switch, memory capacity is less, which can result in reduced support for a feature, for example, allowing fewer MAC addresses.

Because the Catalyst C Gigabit Ethernet switch supports only the default template, entering the sdm prefer global configuration command has no effect. See the sdm prefer and show sdm prefer commands in the next section for details on the features supported. Use the auto qos video interface configuration command on the switch stack or on a standalone switch to automatically configure quality of service QoS for video within a QoS domain.

Use the no form of this command to return to the default setting. When auto-QoS is enabled, it uses the ingress packet label to categorize traffic, to assign packet labels, and to configure the ingress and egress queues. DSCP CoS SRR 13 shared. Ingress queues support shared mode only. Use this command to configure the QoS appropriate for video traffic within the QoS domain.

The QoS domain includes the switch, the network interior, and edge devices that can classify incoming traffic for QoS. You can fine-tune the auto-QoS configuration after you enable auto-QoS. An existing user configuration can cause the application of the generated commands to fail or to be overridden by the generated commands.

These actions occur without warning. If all the generated commands are successfully applied, any user-entered configuration that was not overridden remains in the running configuration. Any user-entered configuration that was overridden can be retrieved by reloading the switch without saving the current configuration to memory.

If the generated commands are not applied, the previous running configuration is restored. If this is the first port on which you have enabled auto-QoS, the auto-QoS-generated global configuration commands are executed followed by the interface configuration commands. If you enable auto-QoS on another port, only the auto-QoS-generated interface configuration commands for that port are executed. When you enable the auto-QoS feature on the first port, these automatic actions occur:.

After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer.

To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map.

To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS.

The Configuration Engine supports standalone and server modes and has these CNS components: Configuration service web server, file manager, and namespace mapping server Event service event gateway Data service directory data models and schema In standalone mode, the Configuration Engine supports an embedded Directory Service.

DeviceID Each configured switch participating on the event bus has a unique DeviceID, which is analogous to the switch source address so that the switch can be targeted as a specific destination on the bus.

Hostname and DeviceID The DeviceID is fixed at the time of the connection to the event gateway and does not change even when the switch hostname is reconfigured. Caution When using the Configuration Engine user interface, you must first set the DeviceID field to the hostname value that the switch acquires after —not before —you use the cns config initial global configuration command at the switch.

Otherwise, subsequent cns config partial global configuration command operations malfunction. Synchronized Configuration When the switch receives a configuration, it can defer application of the configuration upon receipt of a write-signal event. Optional For port number , enter the port number for the event gateway. The default port number is Optional Enter backup to show that this is the backup gateway.

If omitted, this is the primary gateway. Optional For failover-time seconds , enter how long the switch waits for the primary gateway route after the route to the backup gateway is established. Optional For keepalive seconds , enter how often the switch sends keepalive messages. For retry-count , enter the number of unanswered keepalive messages that the switch sends before the connection is terminated.

The default for each is 0. Optional For reconnect time , enter the maximum time interval that the switch waits before trying to reconnect to the event gateway. Optional For source ip-address , enter the source IP address of this device. Step 4 show cns event connections Verify information about the event agent. Step 5 show running-config Verify your entries. Step 6 copy running-config startup-config Optional Save your entries in the configuration file.

Switch config cns event You can enable the Cisco IOS agent with these commands: The cns config initial global configuration command enables the Cisco IOS agent and initiates an initial configuration on the switch. The cns config partial global configuration command enables the Cisco IOS agent and initiates a partial configuration on the switch. You can then use the Configuration Engine to remotely send incremental configurations to the switch.

Enabling an Initial Configuration Beginning in privileged EXEC mode, follow these steps to enable the CNS configuration agent and initiate an initial configuration on the switch: Command Purpose Step 1 configure terminal Enter global configuration mode. Step 3 cli config-text Enter a command line for the CNS connect template.

Step 5 exit Return to global configuration mode. Step 6 cns connect name [ retries number ] [ retry-interval seconds ] [ sleep seconds ] [ timeout seconds ] Enter CNS connect configuration mode, specify the name of the CNS connect profile, and define the profile parameters. Enter the name of the CNS connect profile.

Optional For retries number , enter the number of connection retries. The range is 1 to The default is 3. Optional For retry-interva l seconds , enter the interval between successive connection attempts to the Configuration Engine.

The range is 1 to 40 seconds. The default is 10 seconds. Optional For sleep seconds , enter the amount of time before which the first connection attempt occurs.

The range is 0 to seconds. The default is 0. Optional For timeout seconds , enter the amount of time after which the connection attempts end.

The range is 10 to seconds. The default is For controller controller-type , enter the controller type. For dlci , enter the active data-link connection identifiers DLCIs.
