Cisco IOS (originally Internetwork Operating System) is a family of software used on most Cisco Systems routers and current Cisco network switches. The Cisco IOS (Internetwork Operating System) is a robust platform that provides a high level of reliable performance within most network infrastructures.
Cisco Catalyst 2960 Series Switch IOS Software. For the following switches:-----Cisco Catalyst WS-2960-48PST-L Switch Cisco Catalyst WS-2960-48TC-L. The Cisco IOS Release 12.2(25)FX runs on all Catalyst 2960 switches. These release notes include important information about this Cisco IOS release and any limitations, restrictions, and caveats that apply to it.
Sometimes in my lab happens that students delete IOS of the switch from its flash. Unfortunately switches does not have rommon to realize quick IOS recovery over tftp. Only one way is over Xmodem.
Huawei Lte Router External Antenna on this page. Cat 2960 switchIOS recovery To speed up the process of the recovery we may setup Xmodem speed to higher rate as default 9600 bits: Set the speed rate to 115200 baud on the switch prompt of the switch: switch: set BAUD 115200 Of course we lose our console session and therefore we need to restart it with the correct speed settings. Then we may realize the recovery. Enter copy command: copy xmodem: flash: filename for our Cat2960-24TTL: switch: copy xmodem: flash:c2960-lanbasek9-mz.122-52.SE.bin Begin the Xmodem or Xmodem-1K transfer now. CCC and start sending of the file over console Xmodem software.
Recovery over HyperTerminal Choose Transfer >Send File. And than we choose as protocol the Xmodem and in filename click Browse and select the Cisco IOS image (.bin file) from the disk to be uploaded. And click Send to send the file, Recovery over Putty Putty does not support Xmodem protocol, tears.
Final steps To boot the new image that we just copied over with the Xmodem procedure issue the boot flash:filename command, as the example shows: switch: boot flash:c2960-lanbasek9-mz.122-52.SE.bin After the Xmodem recovery, we set the BAUD rate back to 9600. If the set BAUD 9600 command does not bring the baud rate to 9600, issue the unset BAUD command in order to bring the baud rate to a default value of 9600 bps.
