Finding the Software Version and Feature Set

The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. A subdirectory contains the files needed for web management. The image is stored on the compact flash memory card.

You can use the show version privileged EXEC command to see the software version that is running on your switch. The second line of the display shows the version.

You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images stored in flash memory. For example, use the dir flash: command to display the images in the flash memory.

Deciding Which Files to Use

The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file contains the Cisco IOS image file and the files needed for the embedded device manager. You must use the combined tar file to upgrade the switch through Express Setup. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.

Cisco IOS Software Image Files lists the filenames for this software release.

Note: If you download the IP services image and plan to use Layer 3 functionality, you must use the Switch Database Management (SDM) routing template. To determine the currently active template, enter the show sdm prefer privileged EXEC command. If necessary, enter the sdm prefer global configuration command to change the SDM template to a specific template. For example, if the switch uses Layer 3 routing, change the SDM template from the default to the routing template. You must reload the switch for the new template to take effect.

Note: Beginning with Cisco IOS Release 15.2(5)E, we no longer release the IE 3000 IP services image. The latest release for the IP services image on the IE 3000 is 15.2(4)EA1.

Archiving Software Images

Before upgrading your switch software, make sure that you archive copies of both your current Cisco IOS release and the Cisco IOS release to which you are upgrading. Keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and verified that the new Cisco IOS image works properly in your network.

Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for information:
http://www.cisco.com/en/US/prod/collateral/iosswrel/ps8802/ps6969/ps1835/prod_bulletin0900aecd80281c0e.html

You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command.

Note: Although you can copy any file on the flash memory to the TFTP server, it is time consuming to copy all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and archive it on an internal host in your network.

You can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP server by using the tftp-server global configuration command.

Upgrading a Switch by Using the CLI

This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image.

Note: Make sure that the compact flash card is in the switch before downloading the software.

To download software, follow these steps:

1. Use Cisco IOS Software Image Files to identify the file that you want to download.

2. Download the software image file. If you have a SMARTnet support contract, go to this URL, and log in to download the appropriate files:

http://software.cisco.com/download/navigator.html

For example, to download the image for an IE 2000 switch, select Products > Switches > Industrial Ethernet Switches > Cisco Industrial Ethernet 2000 Series Switches, then select your switch model. Select IOS Software for Software Type, then select the image you want to download.

3. Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP server is properly configured.

For more information, see the “Assigning the Switch IP Address and Default Gateway” chapter in the applicable document for your switch as listed in Methods for Assigning IP Information.

4. Log into the switch through the console port or a Telnet session.

5. (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC command:

Switch# ping tftp-server-address

 

For more information about assigning an IP address and default gateway to the switch, see Methods for Assigning IP Information.

6. Download the image file from the TFTP server to the switch.

If you are installing the same version of software that currently exists on the switch, overwrite the current image by entering this privileged EXEC command:

Switch# archive download-sw /overwrite /reload tftp://location /directory /image-name.tar

 

The command above untars/unzips the file.The system prompts you when it completes successfully.

–The /overwrite option overwrites the software image in flash memory with the downloaded one.

If you specify the command without the /overwrite option, the download algorithm verifies that the new image is not the same as the one on the switch Flash device. If the images are the same, the download does not occur. If the images are different, the old image is deleted, and the new one is downloaded. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message displays.

–The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.

–For // location, specify the IP address of the TFTP server. or hostname.

–For / directory / image-name .tar, specify the directory and the image to download. Directory and image names are case sensitive. The directory is for file organization and it is generally a tftpboot/user-ID path.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch:

Switch# archive download-sw /overwrite tftp://198.30.20.19/image-name.tar

 

You can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message displays.

Upgrading IOS and FPGA on the Ethernet Switch Module (ESM)

This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image.

To download software, follow these steps:

1. Refer to Deciding Which Files to Use to identify the file that you want to download.

2. Download the software image file. If you have a SMARTnet support contract, go to the URL below and log in to download the appropriate files.

http://software.cisco.com/download/navigator.html

For example, to download the image for a Connected Grid 10-Port Ethernet Switch Module Interface Card, select Products > Cisco Interfaces and Modules > Connected Grid Modules > Connected Grid 10-Port Ethernet Switch Module Interface Card. Select IOS Software for Software Type, then select the image you want to download.

Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP server is properly configured. For more information, see the “Assigning the Switch IP Address and Default Gateway” chapter in the applicable document listed in Methods for Assigning IP Information.

3. Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP server is properly configured.

4. Log in to the switch through the console port or a Telnet session.

5. (Optional) Ensure that you IP connectivity to the TFTP server by entering this privileged EXEC command:

Switch# ping tftp-server-address

 

6. Download the image file from the TFTP server to the switch.

If you are installing the same version of software that currently exists on the switch, overwrite the current image by entering this privileged EXEC command:

 Switch# archive download-sw /overwrite tftp: //location /directory /image-name.tar

 

The command above untars/unzips the file.The system prompts you when it completes successfully.

–The /overwrite option overwrites the software image in flash memory with the downloaded one.

If you specify the command without the /overwrite option, the download algorithm verifies that the new image is not the same as the one on the switch Flash device. If the images are the same, the download does not occur. If the images are different, the old image is deleted, and the new one is downloaded. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message displays.

–The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.

–For // location, specify the IP address of the TFTP server. or hostname.

–For / directory / image-name .tar, specify the directory and the image to download. Directory and image names are case sensitive. The directory is for file organization and it is generally a tftpboot/user-ID path.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch:

Switch# archive download-sw /overwrite tftp://198.30.20.19/image-name.tar

 

You can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message displays.

 

7. After the download and the untar are complete, power cycle the CGR2010.

Documentation Updates

■On all IoT switches: As part of tightening security, enable secret 0, will automatically be converted to authentication type ‘9’ in
Cisco IOS release 15.2(7)E4 and later. When ‘Type 9’ encryption is enabled on low-end platforms (CGS2520, IE 2000, IE 2000U, and IE3000), Device Manager users will experience an approximate delay of two minutes before the Device Manager pages open.

To workaround this issue, Device Manager users on low-end platforms are advised to configure authentication type ‘5’ using the CLI command: enable algorithm-type md5 secret <password>.
