Two kinds of common Cisco switch fault recovery scheme of the classic example of

I believe S2326TP-EI many using Cisco router users have encountered such problems, it doesn't matter, we analyzed two kinds of Cisco switches troubleshooting common method. Several former unit bought a new Cisco switch Cisco, 10000000000000, 100000000000000, 1000000000000000 adaptive matched the Cisco WS-X6548-GE-TX in April last year before the new 48 RJ-45 switching module.

The Cisco software launch always lags behind the hardware configuration of Cisco switch failure criteria, so get the hand of 12.2 (14) SX1 version of IOS doesn't support this module. Then find the new version to support the WS-X6548-GE-TX module of the IOS ready to upgrade. The result is one after another to.

Cisco switch failure problem: no RJ-45 interface

The WS-X6548-GE-TX 48 RJ-45 switching module can not be used, Cisco switch fault and not with the other with a RJ-45 interface module. How can this be done? Because Cisco TFTPServer upgrade must be Cisco switch fault and on the network with a TFTP Server PC.

After a search, finally found a super engine 720 above a RJ-45 like interface, next to Link written the words, play! The cable plug for a try, that light does not light. I thought there was hope mood fell to the bottom, but don't give up.

Because this interface is the only hope, or using XMODEM transmitted 41000000000000 IOS just let me and step back. Because I once passed through an Cisco switch fault by using XMODEM IOS, also more than two trillion size, for two hours. 41000000000000? Was fastest for 30 hours!

He began to search the internet...... , finally found the problem: the original port2 super engine 720 on the two mode is a RJ-45 interface, and a SFP (asmallform-factorpluggable) interface. The default setting is SFP, you use the RJ-45 interface must change settings. Enter the command: Router (config) #interfacegigabitethernet 5/2Router (config-if) #media-typerj45Router (config-if) #no shutdown. Light orange finally turned green. Call...... Long breath. Thought, to a lot of Cisco switch fault upgrade, the next thing will be easy! Who knows the way and didn't stop.

Cisco switch failure problem: TFTP transmission protocols support only 32000000000000?

Next to the interface with management address, then back out the original IOS. Typing in the super terminal global mode command: Router#copysup-bootflash:s72033-pk9sv-mz.122-14.SX1.bintftp://192.168.1.1. TFTP Server appeared a series of # name, all OK! Wait! Who knows the watch time, will finish the system prompts: timeout! Writeerror! I fainted, network transmission error bad?? insufficient disk space are not ah?. Try again, or so.

Have a look down IOS medium was 32000000000000, and the complete IOS 32100000000000. How poor a little ah! Is it TFTP software problems Cisco switch failure, version is too low? The Internet to download a third party TFTPServer a try, or the results of such. But for 3Com TFTPServer, the smaller, to 16000000000000 is disconnected, the system prompts or timeout and write error.

Careful analysis, finally found the key Cisco switch failure problem. Transmission of two times, one is 32000000000000, one is 16000000000000. Even the number of bytes are not bad, certainly not the problem of transmission line. To find out the original data, TFTP (TrivialFileTransferProtocol) trivial file transfer protocol maximum support 32000000000000 file transmission. Then he found Cisco documents, a query, find out second solutions, using the FTP on the line.

So to construct the FTP service on PC, type the following command: Router#configureterminalRouter Cisco switch failure (config) # IP FTP username usernameRouter (config) # ipftp password password Router (config) #endRouter#copysup-bootflash: s72033-pk9sv-mz.122-14.SX1.binftp:[//[username[: password]@]192.168.1.1] this S2326TP-EI-AC very successful! Not for a few minutes, the system prompts successful!
