Ctrl-N or the Down Arrow key 1. Returns to more recent commands in the history buffer after recalling commands with Ctrl-P or the Up Arrow key. While in EXEC mode, lists the last few commands you entered. Because the CLI is divided into many different modes, the commands available to you at any given time depend on the mode that you are currently in. Entering a question mark?

User EXEC mode contains only a limited subset of commands. To have access to all commands, you must enter privileged EXEC mode, normally by using a password. Most EXEC commands are one-time commands. For example, show commands show important status information, and clear commands clear counters or interfaces. The EXEC commands are not saved when the software reboots.

Configuration modes allow you to make changes to the running configuration. If you later save the running configuration to the startup configuration, these changed commands are stored when the software is rebooted. To enter specific configuration modes, you must start at global configuration mode. From global configuration mode, you can enter interface configuration mode and a variety of other modes, such as protocol-specific modes.

If a valid software image is not found when the software boots or if the configuration file is corrupted at startup, the software might enter ROM monitor mode. It also shows examples of the prompts displayed for each mode. Use the logout command. From user EXEC mode, use the enable command. To return to user EXEC mode, use the disable command. From privileged EXEC mode, use the configure terminal command. Router config. To return to privileged EXEC mode from global configuration mode, use the exit or end command.

From global configuration mode, specify an interface using an interface command. Router config-if. To return to global configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

The router boots up or accesses diagnostic mode in the following scenarios:. In some cases, diagnostic mode will be reached when the Cisco IOS process or processes fail. In most scenarios, however, the router will reload. A user-configured access policy is configured using the transport-map command that directs a user into diagnostic mode.

A break signal Ctrl-C , Ctrl-Shift-6 , or the send break command is entered and the router is configured to go to diagnostic mode when the break signal is received. Router diag. If failure of the Cisco IOS process is the reason for entering diagnostic mode, the Cisco IOS problem must be resolved and the router rebooted to get out of diagnostic mode.

If the router is in diagnostic mode because of a transport-map configuration, access the router through another port or by using a method that is configured to connect to the Cisco IOS CLI.

Press the Break key during the first 60 seconds while the system is booting. To exit ROM monitor mode, manually boot a valid image or perform a reset with autoboot set so that a valid image is loaded.

The IOS process or processes fail, in some scenarios. In other scenarios, the system resets when the IOS process or processes fail. A user-configured access policy was configured using the transport-map command that directs the user into the diagnostic mode. A send break signal Ctrl-C or Ctrl-Shift-6 was entered while accessing the router, and the router was configured to enter diagnostic mode when a break signal was sent.

In the diagnostic mode, a subset of the commands that are available in user EXEC mode are made available to the users. Among other things, these commands can be used to:. Inspect various states on the router, including the IOS state. Provide methods of restarting the IOS or other processes. Reboot hardware, such as the entire router, a module, or possibly other hardware components. The diagnostic mode provides a more comprehensive user interface for troubleshooting than previous routers, which relied on limited access methods during failures, such as ROMMON, to diagnose and troubleshoot Cisco IOS problems.

The diagnostic mode commands can work when the Cisco IOS process is not working properly. These commands are also available in privileged EXEC mode on the router when the router is working normally. You can also get a list of keywords and arguments associated with any command by using the context-sensitive help feature.

To get help that is specific to a command mode, a command, a keyword, or an argument, use one of the following commands. Provides a brief description of the help system in any command mode. Provides a list of commands that begin with a particular character string. There is no space between the command and the question mark. Lists all the commands that are available for a particular command mode. Lists the keywords or arguments that you must enter next on the command line.

There is a space between the command and the question mark. This section provides information about how to display the syntax for a command. The syntax can consist of optional or required keywords and arguments. To display keywords and arguments for a command, enter a question mark?

For example, if you are in global configuration mode and want to see all the keywords and arguments for the arap command, you should type arap? On older keyboards, the carriage return key is the Return key. On most modern keyboards, the carriage return key is the Enter key. The following table shows examples of using the question mark?

Enter the enable command and password to access privileged EXEC commands. Enter the configure terminal privileged EXEC command to enter global configuration mode. You are in global configuration mode when the prompt changes to Router config.

The following is a list of technology packages: Note In Cisco Series Integrated Series Routers, although L2TPv2 sessions comes up without appxk9, you need the appxk9 license for the traffic to go through the sessions.

Performance The performance feature, which allows for increased throughput, is enabled by the performance license. To exit global configuration mode, enter exit. You have to deregister and register back the device from the CSSM to execute the boost license command. Device show running-config include throughput platform hardware throughput level boost Save the configuration and reload the device to enable Boost performance license.

Boost Performance License in Smart License Mode This section describes the processes to activate and deactivate the Boost performance license from the device with two use-cases.

Enable the boost performance license : Boot the device in Smart License mode. Return of license : The device is in the smart license mode with boost performance command configured.

Note The command is removed from the configuration, but the license is released only after the device is reloaded. The throughput level does not take effect until the device is reloaded. The license visibility is available till the device is reloaded. The boost performance behavior is determined by the availability of the license in its Smart Account with Boost Performance activated in CSL: To configure the throughput level, perform the following steps and to upgrade the throughput level use the Configure the device with the platform hardware throughput level boost command and then use show running-config to check if the boost performance license is activated.

When boost performance is in use: Device platform hardware throughput level boost Device show license to ensure that Smart License and Boost performance licenses are enabled. Remove Smart License Device no license smart enable Check the availability of the boost performance license, you may decide to retain the boost command.

No extra reload is required. When boost performance is not in use : Use no platform hardware throughput level boost in the show running-configuration. To remove Smart License, use no license smart enable Check the availability of the boost permanent license to add the boost keyword. Boost Performance is activated and is in-use after reload Note If there is no permanent license available, then no boost performance command and functionality is likely to change.

Device configuration terminal To remove Smart License, use no license smart enable Device no license smart enable Device exist To remove Smart License, reload the router. Device configure terminal Enter yes to accept the end-user license agreement.

Step 2. Broadcast counters issue is seen on Cisco ISR. Cisco Series ISR configured with a boot statement pointing to the "flash:" directory will get stuck in a boot loop. Cisco 44xx ISR crashes under low output memory conditions. After power outage, startup configs were missing once the router came back up. When we issue "copy run start all" on 4K platforms, the router copies some default commands into start-up.

Missing label information on MPLS TE midpoints in either in show mpls forwarding label or show mpls traffic-eng tunnel. Router displays the folowing log constantly on the console, this seems to be a memory leaking o. The line "no cdp enable" is added to the running configuration of a subinterface on a Cisco ISR after the device is reloaded. When you execute the show vlans dot1q command, it provides incorrect statistics for non-native VLANs. Cisco ISRcrashes with following error message:.

Cisco ISR: password recovery mode is not getting properly cleared. NIM-ES2 duplex mismatches after there is a change in speed auto. Cisco ISR provides incorrect values for traffic in subinterfaces. Cisco 44xx ISR cannot send large, fragmented or reassembled packets into containers. Cisco ISR crashes with an unrecoverable error. Cisco Series ISR ignores network-clock synchronization command on boot up. Committed memory increases leading to a crash.

This is due to increase in the process command. Cisco Series ISR does not need a netsync startup delay. After downgrading the firmware image of some modules while leaving the Cisco Series ISR router up and running, the module may fail to come online. Topology not shown on PfR monitoring page on prime. The following messave is seen repeatedly from the router's side:. Packet loss is seen while changing the configuration from default to default.

When you reload module using hardware-module, call-history needs to be updated. NGIO control packet path error handling may cause module reset. When you run the Cisco IOS Cisco Series ISR does not provide the warning message when the throughput licensed limit is reached. While sending two egress stress streams to two of the ports of Cisco 4-Port and 8-Port Layer 2 Gigabit EtherSwitch Network Interface Module at the same time, traffic rate is 1 Gpbs for each port, and the packet size is 64 bytes.

The performance is less than expected. Front Panel GigE interfaces takes long time nearly 5 Min to come up after changing the configured Speed value to In a Cisco ISR installed with two power supplies, if one of the power supply is removed and re-inserted, the output of the show inventory command displays incorrect values.

The E-Series Server module shows memory leak issue and the router displays the following error message: NGIO control packet loss detected. Intermittent boot up issue is seen with most of the CCO images with Controller is down and the receiver is getting AIS in E1 unframed mode. The crash is seen even if this interface is down.

Apply the following view to exclude cEigrpInterfaceEntry from being polled:. Avoid flapping crypto session under stress traffic. Reinsert the same type of SKU to resolve the problem. Cisco ISR series platforms reload when you attempt to use jumbo frames larger than 2k bytes on the management interface GigabitEthernet0.

Cisco ISR platforms allow up to 4k bytes jumbo frame configuration on the management interface GigabitEthernet0. However, the interface does not support jumbo frames, and if the device is configured with an MTU larger than 2k bytes, and packets larger than 2k bytes are sent to the interface, it will result in a system reload.

All hardware versions of Cisco ISR series platforms are impacted by this problem. Service module reloads after disabling IP routing at line rate. The Micro-loader section of the output for the show software authenticity running command is missing.

This problem occurs when you issue the show software authenticity running command. Cisco ISR reloads with large ping packets using a traffic generator while using multicast configuration. The router reloads while trying to ping using a large byte packet through it while using multicast configuration. The reload is not observed when a regular or a small-sized ping packet is sent. Router reloads during boot up. Interfaces render unusable. This problem occurs when user tries to upgrade or downgrade the image.

Booting the same image through reload does not trigger this issue. This issue occurs once in thousand router reloads in development test environment.

The isdn incoming-voice voice command is not supported on Cisco ISR though the functionality is intact. CLI support is required for backward compatibility. This problem occurs when you use the invalid isdn incoming-voice voice command. The rate at which IPSec tunnels come up is a little slow when the maximum supported tunnels are configured.

This display is an indication that the router has already automatically cleared the condition and can be safely ignored. This condition is very rare and can occur on any type of router reset including a power cycle.

The display is an indication that the device has already automatically applied the workaround. No further workarounds are required, and the router can be safely used as normal with this display. The problem occurs during initial boot with modules inserted. Some of the Cisco ISRs modules do not come up.

This problem occurs during initial boot up or when a new module is inserted into the router. Cisco ISR Ucode reloads when the crypto session is cleared. This problem occurs when the crypto session is cleared. A small number packets are dropped in the backplane switch on the FFP port.

This problem occurs when the Zone-based firewall is configured and no need to attach the service-policy to zone-pair. This is not seen in releases prior to 3. SFP fails each time router boots up and during the first time installation. All SFPs are not affected. Failed to add The router reloads due to low memory, fails to include IO related memory commands to assist in diagnosing the cause of the device running out of memory.

This problem occurs when the router reloads due to low memory. Configure the exception crashinfo dump command and troubleshoot the memory issue. Enter configuration commands, one per line. IPsec ECN status is shown as disabled by hardware status.

This problem occurs while checking show crypto ipsec sa output. Traceback generated while allocating a scheduling node before the resources are depleted. The failure adversely affects the current and subsequent configuration events. If the BQS resource manager returns synchronously after it has activated the scheduling node, it generates the following traceback after resuming processing of the same scheduling node to place the children in the tree and process the scheduling node rate:.

The failure gives a false alarm about resources outage. The traceback is caused by an erroneous logic when the scheduling node is already marked as ACTIVE before it is completely processed. For NAT64, there is no workaround. This problem occurs when a large packet is sent over a small MTU and that results in more than eight fragments.

When you add a modem to the auxiliary port of a Cisco ISR X and then configuring it, the router reloads. Do not use a modem on the auxiliary port. This configuration is not supported. Encpas counter in show crypto ipsec sa command may occasionally show incorrect value.

This problem occurs when the IPSec tunnels configured and used on the device. Cisco ISR platform reloads with a segmentation fault. This problem occurs when the traffic is greater than 90Mbps without installing HSECK9 license and when you configure the license boot level securityk9 command on the router.

During test failures, users will not be notified. The logs do not contain information on the failures. This message doesn't give enough information for the user to take the proper course of action.

This message does not indicate that the crypto self-test has failed. When you use the show power inline command on Cisco ISR device, it does not display any output about the power consumed by the PD connected to SM module s.

You have to connect a PD to a front panel port of the SM module. The Cisco ISR X device generates a traceback while allocating a scheduling node before the resources are depleted. If the BQS resource manager returns synchronously after it has activated the scheduling node, it generates the following traceback after resuming processing of the same scheduling node to place the children in the tree and process the scheduling node rate.

In some conditions, Cisco ISR platform displays Cisco-proprietary internal keywords as part of the error message. Displays Cisco-proprietary internal keywords as part of the error message. Also, the member links queue grows beyond the set queue-limits. This problem occurs when a large packet is sent over a small MTU and that results in more than 8 fragments. When you add a modem to the auxiliary port of the Cisco ISR X device and then configuring it, the device reloads.

This configuration is currently unsupported. The defect affects the ISR products. The serial interface and Service-Engine share the same interface name. This problem occurs when you install any kind of serial card and Service-Engine card, then run the show interface description command.
