Upgrade Cisco IOS software features through the Cisco Software Activation tool. It authorizes and enables the feature set on Cisco IE 2000 switch series based on the type of license. Enable features either through a licensing upgrade only, or both a licensing and software upgrade.
On Cisco IE 2000 switches, to upgrade from LAN Lite to LAN Base you do not require new software releases. However, the minimum software version required for Enhanced LAN Base is 15.0(2)EB. Running a release prior to 15.0(2)EB will require a software upgrade first before the license upgrade. See Software Activation Licensing Upgrade for detailed steps:
http://www.cisco.com/en/US/docs/switches/lan/cisco_ie2000/software/release/15_0_2_eb/upgrade/guide/ie2000_ug.html
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. On IE 2000, the image can be stored on the internal flash or external SD 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 also can use the dir filesystem : privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.
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 Express Setup. You must use the combined tar file to upgrade the switch through Express Setup. To upgrade the switch through the CLI, use the tar file and the archive download-sw privileged EXEC command.
Before upgrading your switch software, make sure that you have archived copies of the current Cisco IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and until you have 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 more 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 take advantage of the available SD card memory by copying the extracted image directory and user configuration to SD card using the command [sync flash: sdflash:] to ensure a backup file is stored safely
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. For more information about the tftp-server command, see the Cisco IOS Configuration Fundamentals Command Reference :
http://www.cisco.com/en/US/docs/ios/fundamentals/command/reference/cf_t1.html
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 On IE2000, the image file can be downloaded to the internal flash or the SD card (if present).
To download software, follow these steps:
Step 1 Use Table 3 to identify the file that you want to download.
Step 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://www.cisco.com/cisco/web/download/index.html
To download the image for a Cisco IE 2000 switch, click Switches > Industrial Ethernet Switches > Cisco IE 2000 Series Switches, and then click on the Cisco IOS software for your specific switch model.
Step 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 Appendix B of the software configuration guide for this release.
Step 4 Log into the switch through the console port or a Telnet session.
Step 5 (Optional) Check 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 the software configuration guide for this release.
Step 6 Download the image file from the TFTP server to the switch. If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command:
The /overwrite option overwrites the software image in flash memory with the downloaded one.
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.
For / directory / image-name .tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive.
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.
You can assign IP information to your switch by using these methods:
For more information about the following new features for this release, please see the associated Configuration Guide here: http://www.cisco.com/c/en/us/td/docs/switches/lan/cisco_ie2000/software/release/15_2_2_e/configuration/guide/scg-ie2000.html
Cisco Open Plug-n-Play agent is a software application that is running on a Cisco IOS or IOS-XE device and provides zero-touch deployment of all new devices. The application facilitates the acquisition and loading of pertinent images, configuration files, and other required files to the device along with notifications for various events. (Cisco IE 2000 only supports Cisco IOS).
Cisco EnergyWise includes software and services that help you measure and manage the energy use of all the connected devices across your networks. IE 2000 supports Cisco EnergyWise version 2.8. For more information, see the Cisco EnergyWise software release notes and the configuration guide here: http://www.cisco.com/c/en/us/td/docs/switches/lan/energywise/version2_8/ios/release/notes/ol23554.html
Smart Install is a plug-and-play configuration and software upgrade feature that provides zero-touch deployment for new switches. You can ship a switch to a location, place it in the network and power it on with no configuration required on the device. For more information, see Smart Install Configuration Guide here: http://www.cisco.com/c/en/us/td/docs/switches/lan/smart_install/configuration/guide/smart_install.html
Note IE2000 can be a Smart Installation Director
You should review this section before you begin working with the switch. 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.
If this happens, uneven traffic distribution will happen 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 random source-ip and dest-ip traffic, configure load balance method as src-dst-ip
– for incrementing source-ip traffic, configure load balance method as src-ip
– for incrementing dest-ip traffic, configure load balance method as dst-ip
– Configure the number of ports in the EtherChannel so that the number is equal to a power of 2 (i.e. 2, 4, or 8)
For example, with load balance configured as dst-ip with 150 distinct incrementing destination IP addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is optimal.(CSCeh81991)
The workaround is to use rate limiting on DHCP traffic to prevent a denial of service attack from occurring. (CSCeb59166)
The workaround is to choose compatible buffer sizes and threshold levels. (CSCea76893)
This is a hardware limitation. The workaround is to disable CDP on all interfaces carrying the RSPAN VLAN on the device connected to the switch. (CSCeb32326)
When a switch or switch stack running Multiple Spanning Tree (MST) is connected to a switch running Rapid Spanning Tree Protocol (RSTP), the MST switch acts as the root bridge and runs per-VLAN spanning tree (PVST) simulation mode on boundary ports connected to the RST switch. If the allowed VLAN on all trunk ports connecting these switches is changed to a VLAN other than VLAN 1 and the root port of the RSTP switch is shut down and then enabled, the boundary ports connected to the root port move immediately to the forward state without going through the PVST+ slow transition.
There is no workaround. (CSCdz42909).
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
The workaround is to enter the switchport access vlan dynamic interface configuration command separately on each port. (CSCsi26392)
The workaround is to remove unnecessary VLANs to reduce CPU utilization when many links are flapping. (CSCtl04815)
Cisco IE 2000 supports IPv4 static routing in the LAN Base image. To access static routing commands, you need to change the SDM template from the default template to lanbase-routing, followed by a switch reload sequence.
The following note is an update to the Regulatory Compliance and Safety Information (RCSI) guide. This note applies to the 61000-4-3 standard listed in the “EMC Interface Immunity” section of Table 1 of the guide.
Note To meet 10V/m or 20V/m Radiated Immunity levels, shielded cables must be used on the uplink ports, G1/1 and G1/2.
This note applies to these SKUs:
– IE-2000-4T-G-L
– IE-2000-4T-G-B
– IE-2000-8TC-G-L
– IE-2000-8TC-G-B

3. From the Settings window, choose Automatically.
5. Click OK to exit the Internet Options window.
Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:
If you change the HTTP port, you must include the new port number when you enter the IP address in the browser Location or Address field (for example, http://10.1.126.45:184 where 184 is the new HTTP port number). 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.
Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:
Note ● IE-2000-4S-TS-G do not have copper ports for PC, a Gigabit GLC-T copper SFP is required to perform express setup.
The following sections provide information about caveats. You can click the issue number to view more information in the Cisco Bug Search tool (login required):
The switch maintains an IP device tracking table to store information about detected hosts. In 15.2(1)EY, IP Device Tracking (IPDT) is globally enabled. To avoid the ARP probing caused by race conditions or duplicate ip addresses (CSCui55905) the IPDT has been disabled at the interface level by default. This includes IE2000 with command [ip device tracking maximum 0]. In 15.2(2)E, a new global command is added to allow a user-defined ARP request source IP instead of using the default source IP 0.0.0.0. The new global command “ip device tracking probe auto-source fallback 0.0.0.x 255.255.255.0 override” allows the user to use the host address of 0.0.0.x in the subnet to avoid any duplicate IP address problems. |

On Cisco IE 2000, you can use an SD card as the boot device and to store a configuration file. (For information about how to use SD card, see Using an SD Card with the Cisco IE 2000 Switch, Cisco IOS Release 15.0(2)EA1 here: http://www.cisco.com/c/dam/en/us/td/docs/switches/lan/cisco_ie2000/hardware/sd-card/sd_card.pdf.) However, because crypto keys are not stored on an SD card for security reasons, you could be locked out from accessing a new switch when you use an SD card to boot up the switch. An enhancement in 15.2(2)E provides for automatic regeneration of the key if SSH is properly configured. This enhancement ensures seamless zero touch replacement of a switch. |
