What is the difference between the running-config file and the startup config file?
A running configuration resides in a device’s RAM, so if a device loses power, all configured commands will be lost. A startup configuration is stored in the nonvolatile memory of a device, which means that all configuration changes are saved even if the device loses power.
What is a running-config file?
The configuration file where router stores the configuration changes when the router is up and running is called the “running-config” file. The running configuration file stores the configuration changes made while the router is up and running. The “running-config” file is stored in RAM.
What is show startup config?
For the Cisco 7000 family, the show startup-config command shows the configuration file specified by the CONFIG_FILE environment variable. The Cisco IOS software informs you whether the displayed configuration is a complete configuration or a distilled version.
Why is it important to load the startup configuration into the running configuration?
Loading the startup configuration into the running configuration ensures that the original startup configuration remains intact if the user saves during the password recovery process.
What is the difference between write memory and copy running-config startup config?
They essentially achieve the same things by saving the running configuration to the memory so that after a reload it retains the same configuration. Write memory is the “ancient” way, and copy running-config startup-config is the “newer way”.
What is the difference between WR and copy run start?
Just remember though, if you are in the wrong configuration register “wr” will lose your configuration after a reload/when you change the configuration register whereas “copy run start” will just copy the contents of the running configuration to the start-up configuration.
What is wr mem?
Or, you can type: do wr mem – which writes the change to memory if your int ‘config’ mode.
What are the two different configuration files?
Two files control system-wide settings: OS2. INI and OS2SYS. INI. Application developers can choose whether to use them or to create a specific file for their applications.
What are running-config and startup config and in which type of memory they reside respectively?
There are two configurations stored in a Cisco router; the startup configuration is stored in nonvolatile RAM (NVRAM) and is only read when the router “starts” up; the other is the running configuration and it is stored in RAM while the router is operating.
Do WR vs copy run start?
What is the command for startup config?
Run command for Startup programs. Starup programs can be configured in System configuration utility. The Run command for opening System configuration utility is msconfig. After running this command select the tab ‘Startup‘ in the configuration utility window. Here you can select which programs need to be launched when a user logs in.
What is a startup config?
The statup-config is the configuration that is loaded when the router boots or powers up. The runnning-config is the current configuration in the router. It may have been modified since the last boot and so might be different.
What is SH running config?
The running-configuration is the config that is in the router’s memory. You change this config when you make changes to the router. Keep in mind that config is not saved until you do a copy running-configuration startup-configuration. This command can be abbreviated sh run.
What is running configuration?
The running configuration file stores the configuration changes made while the router is up and running. The “running-config” file is stored in RAM. The “running-config” file is NOT persistent, which means that the changes made in the “running-config” while the router is running are not retained after a reboot.
