Resetting the Password on a 3560

The below Method is for when password Recovery Mechanism is Enabled For other situations and scenarios see the link below.

Step 0 : Press the Mode button, and at the same time, reconnect the power cord to the switch.

You can release the Mode button a second or two after the LED above port 1 goes off. Several lines of information about the software appear along with instructions:

The system has been interrupted prior to initializing the flash file system. The following
commands will initialize the flash file system, and finish loading the operating system
software#

flash_init

load_helper

boot

Step 1 Initialize the Flash file system:

switch: flash_init

Step 2 If you had set the console port speed to anything other than 9600, it has been reset to that particular speed. Change the emulation software line speed to match that of the switch console port.

Step 3 Load any helper files:

switch: load_helper

Step 4 Display the contents of Flash memory:

switch: dir flash:

The switch file system appears:

Directory of flash:

13  drwx         192   Mar 01 1993 22:30:48  c3560-i5-mz.121.19-EA1

11  -rwx        5825   Mar 01 1993 22:31:59  config.text

18  -rwx         720   Mar 01 1993 02:21:30  vlan.dat

16128000 bytes total (10003456 bytes free)

Step 5 Rename the configuration file to config.text.old.

This file contains the password definition.

switch: rename flash:config.text flash:config.text.old

Step 6 Boot the system:

switch: boot

You are prompted to start the setup program. Enter N at the prompt:

Continue with the configuration dialog? [yes/no]: N

Step 7 At the switch prompt, enter privileged EXEC mode:

Switch> enable

Step 8 Rename the configuration file to its original name:

Switch# rename flash:config.text.old flash:config.text

Step 9 Copy the configuration file into memory:

Switch# copy flash:config.text system:running-config
Source filename [config.text]?
Destination filename [running-config]?

Press Return in response to the confirmation prompts.

The configuration file is now reloaded, and you can change the password.

Step 10 Enter global configuration mode:

Switch# configure terminal

Step 11 Change the password:

Switch (config)# enable secret password

The secret password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, and allows spaces but ignores leading spaces.

Step 12 Return to privileged EXEC mode:

Switch (config)# exit
Switch#

Step 13 Write the running configuration to the startup configuration file:

Switch# copy running-config startup-config

Power and Memory Allocation errors on a 3550

%SYS-2-MALLOCFAIL & %ILPOWER-3-CONTROLLER ERR

I received these two errors today on a 3550 Running CCME

--%ILPOWER-3-CONTROLLER ERR

This Error is due to power spike on an interface most probably from an IP phone, causing the power controller to go down shut and then no shut the interface. proper grounding for the IP phone.

--%SYS-2-MALLOCFAIL

The Error is due to unavailability of the free memory block, a process is trying to write data on for details see.
