The command output was updated to display information about free regions. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(33)SRE This command was modified. The output was updated to display heap region memory size in chunks of 16 MB. Usage Guidelines This command can be useful for troubleshooting system bus errors. The system encounters a bus error when the processor tries to access a memory location that either does not exist (a software error) or does not respond properly (a hardware problem). To use the show region command to troubleshoot a bus error, note the memory location address from the show version command, the show context command, or from the system error message that alerted you to the bus error. The show region command can then be used to determine if that address is a valid memory location. For example, in the output of the show version command after a system restart caused by a bus error, you will see output similar to “System restarted by bus error at PC 0x30EE546, address 0xBB4C4.” In this case, the memory location that the router tried to access is 0xBB4C4. If the address falls within one of the ranges in the show region output, it means that the router was accessing a valid memory address, but the hardware corresponding to that address is not responding properly. This indicates a hardware problem. If the address reported by the bus error does not fall within the ranges displayed in the show region output, this error means that the router was trying to access an address that is not valid, which indicates that it is a Cisco IOS software problem. More detailed information is available on Cisco.com in Tech Note #7949, "Troubleshooting Bus Error Crashes". Transient Memory Allocation The Transient Memory Allocation feature is enabled on platforms like the Cisco 7200 series router and the Cisco 10000 series router. This feature allocates all transient memory in a separate memory address space (separate region), so that there is no interleaving of static and transient memory blocks. Hence, the output of the show region command will have heap region memory size in chunks of 16 MB. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/command/cf_command_ref/show_protocols_through_showmon.html#wp2760878733 Page 5 of 155 Examples The following is sample output from the show region command: Router# show region Region Manager: Start End Size(b) Class Media Name 0x0C000000 0x0FFFFFFF 67108864 Iomem R/W iomem 0x20000000 0x2FFFFFFF 268435456 Local R/W extended_2 0x50000000 0x5FFFFFFF 268435456 Local R/W extended_1 0x60000000 0x7BFFFFFF 469762048 Local R/W main 0x600090F8 0x6200A807 33560336 IText R/O main:text 0x62014C50 0x62F5B1EF 16016800 IData R/W main:data 0x62F5B1F0 0x6333500F 4038176 IBss R/W main:bss 0x63335010 0x6359A0D3 2511044 Local R/W main:saved-data 0x6359A0D4 0x6459A0D3 16777216 Local R/W main:heap 0x7B000000 0x7BFFFFFF 16777216 Local R/W main:heap 0x80000000 0x8BFFFFFF 201326592 Local R/W main:(main_k0) 0xA0000000 0xABFFFFFF 201326592 Local R/W main:(main_k1) Free Region Manager: Start End Size(b) Class Media Name 0x6459A12C 0x7AFFFFA7 380001916 Local R/W heap The following table describes the significant fields shown in the display.

Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware. Cisco IOS XE Release 2.1 This command was introduced on the Cisco ASR 1000 Series Routers and the following enhancements were introduced: This command was introduced in diagnostic mode. The command can be entered in both privileged EXEC and diagnostic mode on the Cisco ASR 1000 Series Routers. The slot argument was introduced. 15.0(1)M The command was modified on Cisco 1800 series routers. The output of the command was modified to let you know that the upgradable ROMMON version is not visible due to the license activity and reload is required. Usage Guidelines Use the show rom-monitor command when the router boots a Cisco IOS software iamge. In this case, the device prompt will be something like “Router>”. Use the showmon command when the device boot to Rom Monitor mode instead of booting a Cisco IOS image. In this case, the device prompt will be something like “rommon n >” where "n" is a number. Note On Cisco 1800 series routers, the show rom-monitor command does not show the version of the upgradable ROMMON. To view the version of the upgradable ROMMON, you may need to reload the router while using the upgradable ROMMON image. If you are using the read-only ROMMON, then the upgradable ROMMON disappears. You need to run the upgrade rom-monitor file command for the upgradable ROMMON. Otherwise, the upgrade rom-monitor preference upgrade command is rejected with the message “No Upgrade ROMMON present, cannot select it.” During ROMMON bootup, if you are running upgradable ROMMON, then the ROMMON first displays the read-only ROMMON message, “Running new upgrade for first time.” This message is followed by the upgradable ROMMON message.

The linenum keyword was added. 12.3(8)T This command was modified. The view full option was added. 12.2(14)SX This command was integrated into Cisco IOS Release 12.2(14)SX. The module number and vlan vlan-id keywords and arguments were added for the Supervisor Engine 720. 12.2(17d)SXB This command was integrated into Release 12.2(17d)SXB and implemented on the Supervisor Engine 2. 12.2(33)SXH This command was modified. The all keyword was added. 12.2(31)SB2 This command was integrated into Cisco IOS Release 12.2(31)SB2. This command was enhanced to display the configuration information for traffic shaping overhead accounting for ATM and was implemented on the Cisco 10000 series device for the PRE3. 12.2(33)SRC This command was integrated into Cisco IOS Release 12.2(33)SRC. 12.2(33)SB This command was modified. Support for the Cisco 7300 series device was added. 12.4(24)T This command was modified in a release earlier than Cisco IOS Release 12.4(24)T. The partition and vrf keywords were added. The module and vlan keywords were removed. 15.0(1)M This command was modified. The output was modified to include encrypted filter information. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/command/cf_command_ref/show_protocols_through_showmon.html#wp2760878733 Page 30 of 155 Release Modification 12.2(33)SXI This command was modified. The output was modified to display Access Control List (ACL) information. Usage Guidelines The show running-config command is technically a command alias (substitute or replacement syntax) of the more system:running-config command. Although the use of more commands is recommended (because of their uniform structure across platforms and their expandable syntax), the show running-config command remains enabled to accommodate its widespread use, and to allow typing shortcuts such as show run . The show running-config interface command is useful when there are multiple interfaces and you want to look at the configuration of a specific interface. The linenum keyword causes line numbers to be displayed in the output. This option is useful for identifying a particular portion of a very large configuration. You can enter additional output modifiers in the command syntax by including a pipe character (|) after the optional keyword. For example, show running-config interface serial 2/1 linenum | begin 3 . To display the output modifiers that are available for a keyword, enter | ? after the keyword. Depending on the platform you are using, the keywords and the arguments for the options argument may vary. Prior to Cisco IOS Release 12.2(33)SXH, the show running-config command output omitted configuration commands set with default values. Effective with Cisco IOS Release 12.2(33)SXH, the show running-config all command displays complete configuration information, including the default settings and values. For example, if the Cisco Discovery Protocol (abbreviated as CDP in the output) hold-time value is set to its default of 180: The show running-config command does not display this value. The show running-config all displays the following output: cdp holdtime 180. If the Cisco Discovery Protocol holdtime is changed to a nondefault value (for example, 100), the output of the show running-config and show running-config all commands is the same; that is, the configured parameter is displayed. Note In Cisco IOS Release 12.2(33)SXH, the all keyword expands the output to include some of the commands that are configured with default values. In subsequent Cisco IOS releases, additional configuration commands that are configured with default values will be added to the output of the show running-config all command. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/command/cf_command_ref/show_protocols_through_showmon.html#wp2760878733 Page 31 of 155 Effective with Cisco IOS Release 12.2(33)SXI, the show running-config command displays ACL information. To exclude ACL information from the output, use the show running | section exclude ip access | access list command. Cisco 7600 Series Device In some cases, you might see a difference in the duplex mode that is displayed between the show interfaces command and the show running-config command. The duplex mode that is displayed in the show interfaces command is the actual duplex mode that the interface is running. The show interfaces command displays the operating mode of an interface, and the show running-config command displays the configured mode of the interface. The show running-config command output for an interface might display the duplex mode but no configuration for the speed. This output indicates that the interface speed is configured as auto and that the duplex mode that is displayed becomes the operational setting once the speed is configured to something other than auto. With this configuration, it is possible that the operating duplex mode for that interface does not match the duplex mode that is displayed with the show running-config command.

These keywords represent a partition of the system’s running configuration state, as a major-descriptor and, in some cases, one or more https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/command/cf_command_ref/show_protocols_through_showmon.html#wp2760878733 Page 43 of 155 minor-descriptors. For example, in the command show running-config partition router eigrp 1 , the major-descriptor for the part argument is the router keyword, and the minor-descriptors for the part argument are the eigrp 1 keywords. The actual list of part keyword options will depend on your system hardware, what feature set you are running, and what features are currently configured on your system. Some examples of command part keyword options are provided here for reference. Use the show running-config partition ? command on your system to view the list of command options available on your system. access-list --Displays all running configuration commands that make up the access-list configuration partition. boot --Displays all running configuration commands that make up the boot configuration partition. class-map --Displays all running configuration commands that make up the class-map configuration partition. global-cdp --Displays all running configuration commands that make up the global CDP configuration partition. interface [type slot /port /number ]--Displays all running configuration commands that make up the interfaces configuration partition or the configuration commands that are applied to the specified interface. line --Displays all running configuration commands that make up the line command configuration partition. policy-map --Displays all running configuration commands that make up the policy-map configuration partition. route-map --Displays all running configuration commands that make up the route-map configuration partition. router [protocol ]--Displays all running configuration commands that make up the router configuration partition, or the configuration commands for the specified routing protocol. service --Displays all running configuration commands that make up the services (small server) configuration partition. snmp --Displays all running configuration commands that make up the SNMP configuration partition. | - Allows for the addition of output modifiers. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/command/cf_command_ref/show_protocols_through_showmon.html#wp2760878733 Page 44 of 155 Command Default None Command Modes Privileged EXEC (#) Command History Release Modification 12.2(33)SRB This command was introduced for Cisco 7600 series images in Cisco IOS Release 12.2SR as part of the “Configuration Partitioning” feature. 12.2(33)SB This command was integrated into Cisco IOS Release 12.2(33)SB and implemented on the Cisco 10000 series. 12.2(33)SXI This command was integrated into Cisco IOS Release 12.2(33)SXI. Usage Guidelines When the Configuration Partitioning feature is enabled, the system groups the configuration state of the device into parts (called “partitions”) for the purpose of generating the virtual running configuration file (the list of configuration commands). The selective processing of the system’s configuration state for the purpose of generating a partial running configuration is called “configuration partitioning.” Note This command is not related to hard drive or flash drive partitioning. This granular access to configuration information offers important performance benefits for high-end routing platforms with very large configuration files, as the system wide generation of a complete virtual configuration file from all components on systems with large and complex configurations can become overly resource intensive and be unacceptably slow. The show running-config partition command allows you to display only the part of the running configuration that you want to examine, while also allowing the system to process only the collection of system components (such as https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/command/cf_command_ref/show_protocols_through_showmon.html#wp2760878733 Page 45 of 155 specific interfaces) that you need to display. This is in contrast to other existing extensions to the show running-config command, which only filter the generated list after all system components have been processed. The Configuration Partitioning feature is enabled by default in Cisco IOS software images that support the feature. To disable the feature, use the no parser config partition command. Examples In the following example, the system generates a view of the running configuration by polling only the components associated with the access-list parts of the running configuration state, and then displays only those access-list-related configuration commands. Router# show running-config partition access-list Building configuration... Current configuration : 127 bytes ! Configuration of Partition access-list ! access-list 90 permit 0.0.0.0 1.2.3.5 access-list 100 permit 10 any any ! end In the following example, only the main configuration partition associated with the interface configuration is queried, and only the configuration commands associated with Fast Ethernet interface 0/1 are displayed.

If you do not enter the password keyword, passwords and other security-sensitive information in the output are replaced with the label “.” The show tech-support command is useful for collecting a large amount of information about your routing device for troubleshooting purposes. The output of this command can be provided to technical support representatives when reporting a problem. Effective with CSCsg71173, password authentication protocol (PAP) and challenge handshake authentication protocol (CHAP) passwords are not displayed in the output of this command. Note This command can generate a very large amount of output. You may want to redirect the output to a file using the show inventory | redirect url command syntax extension. Redirecting the output to a file also makes sending this output to your technical support representative easier. For more information about this option, see the command documentation for show | redirect . https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/command/cf_command_ref/show_protocols_through_showmon.html#wp2760878733 Page 93 of 155 The show tech-support command displays the output of a number of show commands at once. The output from this command varies depending on your platform and configuration. For example, access servers display voice-related show command output. Additionally, the show protocol traffic commands are displayed for only the protocols enabled on your device. For a sample display of the output of the show tech-support command, see the individual show command listed.
