New Features in Cisco IOS Release 15.2(6)E
New Feature Summary for Cisco IOS Release 15.2(6)E lists new features added in Cisco IOS Release 15.2(6)E.
■ ■ PRP provides hitless redundancy (zero recovery time) after a failure by providing end nodes, identified as dually-attached nodes (DANs) provide access to two independent, disjointed, parallel networks (LAN-A, LAN-B). (IEC 62439-3) |
|||
Precision time Protocol (PTP) over Parallel Redundancy Protocol (PRP) |
PTP is supported over both LAN A and LAN B in the PRP network to provide redundancy for PTP. |
Parallel Redundancy Protocol (PRP) for IE 4000, IE 4010, and IE 5000 Switches |
|
High-availability Seamless Redundancy (HSR) is defined in International Standard IEC 62439-3-2016 clause 5. HSR is similar to Parallel Redundancy Protocol (PRP) in providing hitless redundancy, but it is designed to work in a ring topology. Instead of two parallel independent networks of any topology (LAN-A and LAN-B), HSR defines a ring with traffic in opposite directions. Port-A sends traffic counter clockwise in the ring, and Port-B sends traffic clockwise. |
High-Availability Seamless Redundancy (HSR) for IE 4000 Configuration Guide |
||
CISCO-ENTITY-SENSOR-MIB is used for SNMP support for sensors on IE switches instead of ENTITY-SENSOR-MIB. |
|||
QinQ support is moved to Lanbase license for IE 4000 and IE 5000. |
|||
Allows tracking and ensures protected communication between peers. |
|||
You can now manage SFPs for IE 4000 switches with SIMATIC STEP7/TIA Portal. |
Pluggable Transceiver (SFP) Configuration Guide for SIMATIC STEP7/TIA Portal |
||
Configure Open Plug and Play (PnP) server settings to allow a switch to send a work request to a PnP server such as Industrial Network Director (IND) to allow further device configuration. |
|||
IND baseline configuration - Changes within Device Manager to make IOT switches IND discoverable. |
|||
FPGA profile support (Feature Mode) - Feature Mode allows for efficient allocation of platform resources for the operation of multiple time sensitive, resilient industrial protocols. Availability of Feature Mode on the switch is determined by supported features, applicable software licenses, and currently applied Feature Mode. The switch is configured with a default mode for the most commonly-used feature for each platform. In a running system, if you deactivate the current active Feature Mode, the default mode will be applied. |
|||
PnP configuration support in Device Manager - On Express setup, the user will point to the PNP server. The switch will send work request to the PNP server for further device configuration. |
|||
MOTD - You can configure a Message of the Day (MOTD) banner to be displayed on the Device Manager Dashboard. |
|||
RSTP/MSTP bridge priority and diagnosis capability - You can select RSTP/MSTP bridge priority per port and display spanning-tree information for the selected VLAN. |
|||
Auto-Logout - If the device manager session is left inactive for the duration of the configured timeout value, the session will be logged out and the user must be re-authenticated. By default session timeout is 3 minutes. The timeout now can be configured only from CLI: ip http session-idle-timeout <1-1200> The session timeout value configured while a user is logged in to DM will be used for auto-logout. |

■1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
■1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
■16 GB available hard disk space (32-bit) or 20 GB (64-bit)
■PC with Windows 7, Windows 10, or Mac OS 10.6.x
■Web browser (Internet Explorer 10.0 or 11.0, or Firefox 48.x and above) with JavaScript enabled
■Straight-through or crossover Category 5 or 6 cable
Express Setup verifies the browser version when starting a session, and it does not require a plug-in.
Upgrading the Switch Software
These are the procedures for downloading software. Before downloading software, read these sections for important information:
■Finding the Software Version and Feature Set
■IOS/IOx Upgrade Considerations
■Upgrading a Switch by Using the CLI
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.
IOS/IOx Upgrade Considerations
Before upgrading, note the following Cisco IOS/IOx version incompatibilities:
■With switch running IOS 15.2.5E2, IOX upgrade from version 1.3 to 1.4 is not supported
■IOx 1.3 is not supported with Cisco IOS 15.2.6E2
We recommend that you upgrade using the IOS and IOx bundle image to move to the higher version software. IOS/IOx bundle images will always have a compatible combination of IOS and IOx.
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:
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:
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:
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:
