You can verify your settings by entering the show logging onboard privileged EXEC command. To log messages to a UNIX syslog server host, use the logging global configuration command. To build a list of syslog servers that receive logging messages, enter this command more than once. To log messages to an internal buffer, use the logging buffered global configuration command. Use it on the switch or on a standalone switch or, in the case of a switch stack, on the stack master.

Optional The size of the buffer created, in bytes. The range is to bytes. The default buffer size is bytes. If a standalone switch or the stack master fails, the log file is lost unless you previously saved it to flash memory using the logging file flash global configuration command. Do not make the buffer size too large because the switch could run out of memory for other tasks. Use the show memory privileged EXEC command to view the free processor memory on the switch. However, this value is the maximum number of bytes available, and the buffer size should not be set to this amount.

To limit messages logged to the console according to severity, use the logging console command. Use the no form of this command to disable message logging. The following example sets the level of console messages received to severity 3 errors and above:.

To store log messages in a file in flash memory, use the logging file flash command. Use it on a standalone switch or, in the case of a switch stack, on the stack master. Optional The maximum logging file size. The range is to The default is bytes. Optional The minimum logging file size.

If the switch is the cluster command switch, but the cluster member switch n does not exist, an error message appears. To get the switch number, enter the show cluster members privileged EXEC command on the cluster command switch. You can use this command to access a cluster member switch from the cluster command-switch prompt or to access a cluster command switch from the member-switch prompt.

For Catalyst XL, XL, , , , , , and switches, the Telnet session accesses the member-switch command-line interface CLI at the same privilege level as on the cluster command switch. For example, if you execute this command at user level on the cluster command switch, the cluster member switch is accessed at user level. If you use this command on the cluster command switch at the privilege level, the command accesses the remote device at the privilege level.

If you use an intermediate enable-level lower than the privilege, access to the cluster member switch is at the user level. For Catalyst and switches running standard edition software, the Telnet session accesses the menu console the menu-driven interface if the cluster command switch is at privilege level If the cluster command switch is at privilege level 1, you are prompted for the password before being able to access the menu console.

Cluster command switch privilege levels map to the cluster member switches running standard edition software as follows:. If the cluster command switch privilege level is from 1 to 14, the cluster member switch is accessed at privilege level 1. If the cluster command switch privilege level is 15, the cluster member switch is accessed at privilege level This command will not work if the vty lines of the cluster command switch have access-class configurations.

You are not prompted for a password because the cluster member switches inherited the password of the cluster command switch when they joined the cluster. This example shows how to start a session with member 3.

All subsequent commands are directed to member 3 until you enter the exit command or close the session:. To rename a file, use the rename command in boot loader mode. This example shows a file named config. You can verify that the file was renamed by entering the dir filesystem: boot loader command. To perform a hard reset on the system, use the reset command in boot loader mode. A hard reset is similar to power-cycling the switch ; it clears the processor, registers, and memory.

The switch prompts you for confirmation before deleting each directory. You can verify that the directory was deleted by entering the dir filesystem: boot loader command. To display messages with sequence numbers when there is more than one log message with the same time stamp, use the service sequence-numbers global configuration command.

This example shows how to display messages with sequence numbers when there is more than one log message with the same time stamp:. To set or display environment variables, use the set command in boot loader mode. Environment variables can be used to control the boot loader or any other software running on the switch.

Use one of the following keywords for variable and the appropriate value for value :. If it is set to 0 or No, the boot loader attempts to automatically boot the system. If it is set to anything else, you must manually boot the switch from the boot loader mode. If the BOOT environment variable is not set, the system attempts to load and execute the first executable image it can find by using a recursive, depth-first search through the flash: file system.

If the BOOT variable is set but the specified images cannot be loaded, the system attempts to boot the first bootable file that it can find in the flash: file system. Valid values are 1, Yes, On, 0, No, and Off. If set to 1, Yes, or On, you can interrupt the automatic boot process by pressing the Break key on the console after the flash: file system has initialized.

Helper files extend or patch the functionality of the boot loader. PS1 prompt —Specifies a string that is used as the command-line prompt in boot loader mode. The Cisco IOS software inherits the baud rate setting from the boot loader and continues to use this value unless the configuration file specifies another setting. Valid values are 50, 75, , , , , , , , , , , , , , , , , , , , and Environment variables that have values are stored in the flash: file system in various files.

Each line in the files contains an environment variable name and an equal sign followed by the value of the variable. A variable has no value if it is not listed in these files; it has a value if it is listed even if the value is a null string. Environment variables that have values are stored in flash memory outside of the flash: file system.

Under typical circumstances, it is not necessary to alter the setting of the environment variables. You can verify your setting by using the set boot loader command. To display the settings of the boot environment variables, use the show boot privileged EXEC command. This example shows the output from the show boot command. The table below describes each field in the display:.
