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 inserted into the switch before downloading the software. Step 1 Use Table 4 to identify the file that you want to download. Step 2 Download the software image file.
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. For more information about assigning an IP address and default gateway to the switch, see the software configuration guide for this release.
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:. Directory and image names are case sensitive.
This example shows how to download an image from a TFTP server at For additional recovery procedures, see the "Troubleshooting" chapter in the software configuration guide for this release. This release is the first software release for the IE switches. PROFINET is useful for industrial automation systems and process control networks, in which motion control and precision control of instrumentation and test equipment are important.
It emphasizes data exchange and defines communication paths to meet speed requirements. 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. Traffic on EtherChannel ports is not perfectly load-balanced. Egress traffic on EtherChannel ports is distributed to member ports on the load-balance configuration and traffic characteristics such as a MAC or IP address.
More than one traffic stream might map to the same member ports based on hashing results calculated by the ASIC. If this situation occurs, 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:. When the rate of received DHCP requests exceeds 2, packets per minute for a long time, the response time might be slow when you are using the console. The workaround is to use rate limiting on DHCP traffic to prevent a denial of service attack from occurring.
The ratio of buffer size to threshold level should be greater than 10 to avoid disabling the queue. 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. Click Settings in the Temporary Internet files area. From the Settings window, choose Automatically. Click OK. Click OK to exit the Internet Options window.
By default, the HTTP server is enabled on the switch. Configures the HTTP server interface for the type of authentication that you want to use. You must enter the aaa new-model interface configuration command for the aaa keyword to appear. 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. The show l2nat statistics command shows that total packets is less than the translated packets after running the traffic for few days.
The sync status is only based on the sync command operation. When you upgrade the Cisco IE image from ieuniversalk9-mz. EY to the next released image for the first time, you need to re-install the same tar images twice to install the correct EDS file. These corrections also apply to the French version of the hardware guide; however, this version has not yet been updated.
