Cisco Catalyst - Recent Questions, Troubleshooting & Support

Hi, Depending on the Supervisor Module model, most likely it's a standard Cisco's "password recovery procedure": Connect to the console Reboot the switch (power cycle) Start pressing Ctrl-C till you get to the BOOTROM Change boot configuration register to 0x2142 (confreg 0x2142) Boot the switch. It will ignore confuguration and boot "empty". Go to "enable mode". Copy startup configuration to running configuration ("copy start run") Change boot register back to 0x2102 (conf t -> conf 0x2102) Write config (write mem) Reboot Good luck, Mike / CCNP, CCDP, CCSP, CCVP Headset Adapters for office phone system

Yes they do support stacking. Here is the info sheet. Cisco Catalyst 2960 Series Switches Products Services

You can add LACP to your Cisco ethernet port config, and configure your Linux to support LACP.

This is usually caused by a bad async controller where dc voltage is not supplied to the ports. There is nothing you can fix to make it pass the check.

Keep your 4-port and just purchase a netgear or linksys 8-port switch. This will increase your port count to 12, but you burn two ports on uplinking. If you need more ports, just get a 16-port switch then. I believe this will be the most cost effective solution.

Here are a couple of ideas...

The Cisco 2960 has a life time warranty. Contact the seller and they should be able to get the switch exchanged at no cost.

flash_init first, then load_helper should work.

There is a possibility of IOS® corruption, so better check on that before using warranty, RMA or dumpster/recycling Error Message SW_VLAN-4-IFS_FAILURE: VLAN manager encountered file operation error: call = [chars] / code = [dec] ([chars]) / bytes transferred = [dec]. Explanation This message means that the VLAN manager received an unexpected error return from an IOS file system (IFS) call while reading the VLAN database. The first [chars] is the IFS operation that failed. The first [dec] is the error code, the second [chars] is the textual interpretation of the error code, and the second [dec] is the number of bytes transferred. Recommended Action Copy the error message exactly as it appears on the console or in the system log, call your Cisco technical support representative, and provide the representative with the gathered information.

No. WS C2960S 48FPS uses the Universal image, but no license is required. The feature is bound to the hardware model type and cannot be changed. For convenience, a single software image is used for all Cisco Catalyst 2960-S Series Switches, regardless of whether they are a LAN Base or LAN Lite model.

Hi I have checked and no data found for that S/N Thanks

Hi Instructions telnet to the IP address of the Cisco switch Enter the telnet access password for the Cisco swict when requested, and then the "Enter" key. Type "enable" at the command prompt, and then the "Enter" key. Enter the Privileged Exec password when requested at the command prompt, and then the "Enter" key. Then enter "configuration terminal" at the command prompt, and then the "Enter" key. Type "interface fastethernet0/1," replacing the "fastethernet0/1" with the name of an interface in which you wish to enable PoE, and then the "Enter" key. Then, while in interface configuration mode, type "power inline auto" and then the "Enter" key. Repeat this step for each interface in which PoE is required. Type "end" at the command prompt and then the "Enter" key, copy running-config Below is some commands to run, I don't have any power on the interface but this will show you if this is working...

shut down the port and then no shut the port.
