Command History

Release	Modification
11.1	This command was introduced.

Usage Guidelines

This command allows slave slots to log error messages of level 2 or higher (critical, alerts, and emergencies).

Examples

In the following example, the router is configured to log important messages from the slave cards to the console:

Router(config)# service slave-log 

The following is sample output generated when this command is enabled:

%IPC-5-SLAVELOG: VIP-SLOT2:

 IPC-2-NOMEM: No memory available for IPC system initialization

The first line indicates which slot sent the message. The second line contains the error message.

service tcp-keepalives-in

service tcp-small-servers

To access minor TCP/IP services available from hosts on the network, use the service tcp-small-servers command in global configuration mode. To disable these services, use the no form of the command.

service tcp-small-servers

no service tcp-small-servers

Syntax Description

This command has no arguments or keywords.

Defaults

Disabled

Command Modes

Global configuration

Command History

Release	Modification
11.1	This command was introduced.

Usage Guidelines

By default, the TCP servers for Echo, Discard, Chargen, and Daytime services are disabled.

When the minor TCP/IP servers are disabled, access to the Echo, Discard, Chargen, and Daytime ports cause the Cisco IOS software to send a TCP RESET packet to the sender and discard the original incoming packet.

Examples

The following example enables minor TCP/ IP services available from the network:

Router(config)# service tcp-small-servers 

service telnet-zero-idle

To set the TCP window to zero (0) when the Telnet connection is idle, use the service telnet-zero-idle command in global configuration mode. To disable this service, use the no form of this command.

service telnet-zero-idle

no service telnet-zero-idle

Syntax Description

This command has no arguments or keywords.

Defaults

Disabled

Command Modes

Global configuration

Command History

Release	Modification
10.0	This command was introduced.

Usage Guidelines

Normally, data sent to noncurrent Telnet connections is accepted and discarded. When the service telnet-zero-idle command is enabled, if a session is suspended (that is, some other connection is made active or the EXEC is sitting in command mode), the TCP window is set to zero. This action prevents the remote host from sending any more data until the connection is resumed. Use this command when it is important that all messages sent by the host be seen by the users and the users are likely to use multiple sessions.

Do not use this command if your host will eventually time out and log out a TCP user whose window is zero.

Examples

The following example sets the TCP window to zero when the Telnet connection is idle:

Router(config)# service telnet-zero-idle

Related Commands

Command	Description
resume	Switches to another open Telnet, rlogin, LAT, or PAD session.

service timestamps

To configure the system to time-stamp debugging or system logging messages, use one of the service timestamps commands in global configuration mode. To disable this service, use the no form of this command.

service timestamps [debug | log] [ uptime | datetime [msec] [localtime] [show-timezone] [year] ]

no service timestamps [debug | log]

Syntax Description

debug	Indicates that the timestamp should be applied to debugging messages.
log	Indicates that the timestamp should be applied to system logging messages.
uptime	Time stamp with the time since the system was rebooted. The time stamp format for uptime is HHHH:MM:SS.
datetime	Time stamp with the date and time. The time stamp format for datetime is MMM DD HH:MM:SS.
msec	(Optional) Include milliseconds in the time stamp.
localtime	(Optional) Time stamp relative to the local time zone.
year	Include the year in the datetime format.
show-timezone	(Optional) Include the time zone name in the time stamp.

Defaults

No time-stamping.

If the service timestamps command is specified with no arguments or keywords, the default is service timestamps debug uptime.

The default for the service timestamps type datetime command is to format the time in Coordinated Universal Time (UTC), with no milliseconds and no time zone name.

The no service timestamps command by itself disables time stamps for both debug and log messages.

To set the local timezone, use the clock timezone zone hours-offset command in global configuration mode.

Command Modes

Global configuration

Command History

Release	Modification
10.0	This command was introduced.
12.2(15)T	The year keyword was added.

Usage Guidelines

Time stamps can be added to either debugging or logging messages independently. The uptime form of the command adds time stamps in the format HHHH:MM:SS, indicating the time since the system was rebooted. The datetime form of the command adds time stamps in the format MMM DD HH:MM:SS, indicating the date and time according to the system clock.

The timestamp will be preceeded by an asterisk or period if the time is potentially inaccurate. Table 61 describes the symbols that proceed the timestamp.

Table 61 Timestamping Symbols for syslog Messages

Symbol	Description	Example
(blank)	Time is authoritative: the software clock is in sync or has just been set manually	15:29:03.158 UTC Tue Feb 25 2003:
*	Time is not authoritative: the software clock has not been set, or is not in sync with configured Network Time Protocol (NTP) servers.	*15:29:03.158 UTC Tue Feb 25 2003:
.	Time is authoritative, but the Network Time Protocol (NTP) is not synchronized: the software clock was in sync, but has since lost contact with all configured NTP servers.	.15:29:03.158 UTC Tue Feb 25 2003:

Examples

In the following example, the user enables time stamps on debugging messages, showing the time since reboot:

service timestamps debug uptime

In the following example, the user enables time stamps on logging messages, showing the current time and date relative to the local time zone, with the time zone name included:

Router(config)#

! The following line shows timestamp with uptime.

1w0d: %SYS-5-CONFIG_I: Configured from console by console

Router(config)# service timestamps log datetime localtime show-timezone 

Router(config)# end

Router#

! The following line shows timestamp with datetime.

.Mar 22 23:13:25 UTC: %SYS-5-CONFIG_I: Configured from console by console

service udp-small-servers

To access minor User Datagram Protocol (UDP) services available from hosts on the network, use the service udp-small-servers command in global configuration mode. To disable these services, use the no form of this command.

service udp-small-servers

no service udp-small-servers

Syntax Description

This command has no arguments or keywords.

Defaults

Disabled

Command Modes

Global configuration

Command History

Release	Modification
11.2	This command was introduced.

Usage Guidelines

By default the UPD servers for Echo, Discard, and Chargen services are disabled.

When the servers are disabled, access to Echo, Discard, and Chargen ports causes the Cisco IOS software to send an "ICMP port unreachable" message to the sender and discard the original incoming packet.

Examples

In the following example, the UDP server (UDP services) is enabled:

Router(config)# service udp-small-servers

set (EEM)

To set the value of a local Embedded Event Manager (EEM) applet variable, use the set command in applet configuration mode. To remove the value of an EEM applet variable, use the no form of this command.

set label _exit_status exit-value

no set label _exit_status exit-value

Syntax Description

label	Unique identifier that can be any string value. Actions are sorted and run in ascending alphanumeric key sequence using the label as the sort key. If the string contains embedded blanks, enclose it in double quotation marks.
_exit_status	Specifies the EEM applet variable name. Currently only the _exit_status variable is supported. •exit-value—Integer value that represents the exit status for the applet. Zero represents an exit status of success, and a nonzero value represents an exit status of failure.

Defaults

No EEM applet variable values are set.

Command Modes

Applet configuration

Command History

Release	Modification
12.3(14)T	This command was introduced.

Usage Guidelines

In EEM applet configuration mode, three types of configuration statements are supported. The event commands are used to specify the event criteria to trigger the applet to run, the action commands are used to specify an action to perform when the EEM applet is triggered, and the set command is used to set the value of an EEM applet variable. Currently only the _exit_status variable is supported for the set command.

Examples

The following example shows how to set the _exit_status variable to represent a success status after an event has occurred three times and an action has been performed.

Router(config)# event manager applet cli-match

Router(config-applet)# event cli pattern {.*interface loopback*} sync yes occurs 3

Router(config-applet)# action 1.0 cli command "no shutdown"

Router(config-applet)# set 1.0 _exit_status 0

set memory debug incremental starting-time

To set the current time as the starting time for incremental analysis, use the set memory debug incremental starting-time command in privileged EXEC mode.

set memory debug incremental starting-time [none]

Syntax Description

none	(Optional) Resets the defined start time for incremental analysis.

Defaults

No default behavior or values.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.3(8)T1	This command was introduced.
12.2(25)S	This command was integrated into Cisco IOS Release 12.2(25)S.

Usage Guidelines

For incremental analysis, a starting point can be defined by using the set memory debug incremental starting-time command. When a starting time is set, only memory allocated after that starting time will be considered for reporting as leaks.

Examples

The following example shows the command used to set the starting time for incremental analysis to the time when the command was issued:

Router# set memory debug incremental starting-time

Related Commands

Command	Description
show memory debug incremental allocation	Displays all memory blocks that were allocated after the issue of the set memory debug incremental starting-time command.
show memory debug incremental leaks	Displays only memory that was leaked after the issue of the set memory debug incremental starting-time command.
show memory debug incremental leaks lowmem	Forces incremental memory leak detection to work in low memory mode. Displays only memory that was leaked after the issue of the set memory debug incremental starting-time command.
show memory debug incremental status	Displays if the starting point of incremental analysis has been defined and the time elapsed since then.
show memory debug leaks	Displays detected memory leaks.

setup

To enter Setup mode, use the setup command in privileged EXEC mode.

setup

Syntax Description

This command has no arguments or keywords.

Command Modes

Privileged EXEC

Command History

Release	Modification
11.1	This command was introduced.

Usage Guidelines

Setup mode gives you the option of configuring your system without using the Cisco IOS Command Line Interface (CLI). For some tasks, you may find it easier to use Setup than to enter Cisco IOS commands individually. For example, you might want to use Setup to add a protocol suite, to make major addressing scheme changes, or to configure a newly installed interface. Although you can use the CLI to make these changes, Setup provides you with a high-level view of the configuration and guides you through the configuration process.

If you are not familiar with Cisco products and the CLI, Setup is a particularly valuable tool because it prompts you for the specific information required to configure your system.

---

Note If you use the Setup mode to modify a configuration because you have added or modified the hardware, be sure to verify the physical connections using the show version EXEC command. Also, verify the logical port assignments using the show running-config EXEC command to ensure that you configure the correct port. Refer to the hardware documentation for your platform for more information on physical and logical port assignments.

---

Before using the Setup mode, you should have the following information so that you can configure the system properly:

•Which interfaces you want to configure

•Which routing protocols you wish to enable

•Whether the router is to perform bridging

•Network addresses for the protocols being configured

•Password strategy for your environment

When you enter the setup EXEC command after first-time startup, an interactive dialog called the System Configuration Dialog appears on the system console screen. The System Configuration Dialog guides you through the configuration process. It prompts you first for global parameters and then for interface parameters. The values shown in brackets next to each prompt reflect either the default settings or the last configured setting.

The prompts and the order in which they appear on the screen vary depending on the platform and the interfaces installed in the device.

You must progress through the System Configuration Dialog until you come to the item that you intend to change. To accept default settings for items that you do not want to change, press the Return or Enter key. The default choice is indicated by square brackets (for example, [yes]) before the prompt colon (:).

To exit Setup mode and return to privileged EXEC mode without making changes and without progressing through the entire System Configuration Dialog, press Ctrl-C.

The facility also provides help text for each prompt. To access help text, press the question mark (?) key at a prompt.

When you complete your changes, the system will automatically display the configuration file that was created during the Setup session. It also asks you if you want to use this configuration. If you answer Yes, the configuration is saved to NVRAM as the startup configuration file. If you answer No, the configuration is not saved and the process begins again. There is no default for this prompt; you must answer either Yes or No.

Examples

The following example displays the setup command facility to configure serial interface 0 and to add ARAP and IP/IPX PPP support on the asynchronous interfaces:

Router# setup

         --- System Configuration Dialog ---

At any point you may enter a question mark '?' for help.

Use ctrl-c to abort configuration dialog at any prompt.

Default settings are in square brackets '[]'.

Command History

Release	Modification
11.3 AA	This command was introduced.
12.3	A timestamp that shows the offset from Coordinated Universal Time (UTC) was added to the show command display.

Usage Guidelines

If Flash memory is partitioned, the command displays the requested output for each partition, unless you use the partition keyword.

The command also specifies the location of the current image.

To display the contents of boot Flash memory on Class A or B file systems, use the show bootflash: command as follows:

Class A Flash file systems

show bootflash: [all | chips | filesys]

Class B Flash file systems

show bootflash:[partition-number] [all | chips | detailed | err]

To display the contents of internal Flash memory on Class A or B file systems, use the show flash: command as follows:

Class A Flash file systems

show flash: [all | chips | filesys]

Class B Flash file systems

show flash:[partition-number][all | chips | detailed | err | summary]

The show (Flash file system) command replaces the show flash devices command.

Examples

The output of the show command depends on the type of Flash file system you select. Types include flash:, bootflash:, slot0:, slot1:, slavebootflash:, slaveslot0:, and slaveslot1:.

Examples of output from the show flash command are provided in the following sections:

•Class A Flash File System

•Class B Flash File Systems

Although the examples use flash: as the Flash file system, you may also use the other Flash file systems listed.

Class A Flash File System

The following three examples show sample output for Class A Flash file systems. Table 62 describes the significant fields shown in the display.

The following is sample output from the show flash: command.

Field	Description
#	Index number for the file.
ED	Whether the file contains an error (E) or is deleted (D).
type	File type (1 = configuration file, 2 = image file). The software displays these values only when the file type is certain. When the file type is unknown, the system displays "unknown" in this field.
crc	Cyclic redundant check for the file.
seek	Offset into the file system of the next file.
nlen	Name length—Length of the filename.
length	Length of the file itself.
date/time	Date and time the file was created. In the example, -08:00 indicates that the given date and time is 8 hours behind Coordinated Universal Time (UTC).
name	Name of the file.
