Junos show configuration

Based on the documentation and the experience we have achieved along years working as a network engineer, we want to condense the hughest ammount of knowledge and experience in the minimum space, in order to become an useful "cheat sheet" able to help the network engineer on a daily basis. We are not showing configuration commands. Juniper has tons of documentation junos show configuration order to configure services.

Note, that all of my code examples will be from my vSRX firewalls in my lab. You can also see what happens when you go into one of the sub-configuration modes. It only shows that we are under interface configuration mode. This is different than JunOS. The prompt stays the same, but you can see which mode we are in above the prompt.

Junos show configuration

Display the configuration that currently is running on the router or switch, which is the last committed configuration. Optional Display one of the following hierarchies in a configuration. Each statement-path option has additional suboptions not described here. See the appropriate user guide or EX Series switch documentation for more information. The portions of the configuration that you can view depend on the user class that you belong to and the corresponding permissions. If you do not have permission to view authentication keys and passwords in the configuration, because the secret permission bit is not set for your user account, the text SECRET-DATA is substituted for that portion of the configuration. If an identifier in the configuration contains a space, the identifier is displayed in quotation marks. Likewise, when you issue the show configuration command with the display set pipe option to view the configuration as set commands, those portions of the configuration that you do not have permissions to view are substituted with the text ACCESS-DENIED. In addition to view, to display the contents under a configuration hierarchy, user should have the required privilege level to view the configuration under that configuration hierarchy.

Show version brief: We use "show version brief" command to view the currently running version on our Junos devices. When upgrading our device, we first check the current OS version that is running on our device. The sample output of "show version brief" command is as shown below. The sample output of "show route protocol rip" command is as shown below. Interfaces are always displayed in numerical order, from the lowest to the highest FPC slot number. The command 'show interface terse match inet' displays the interfaces that are provided with an IPv4 addresses. This command displays only the lines on our router with the inet string.

I saw couple of JUNOS related post on Packet Pushers, so I thought of writing about useful show commands that can be captured during verification or troubleshooting. Juniper routers are divided into two different parts, known as the control plane and the forwarding plane. The control plane is where your routing-related processes are running, and the forwarding plane is where actual forwarding of data takes place based on the information learned from the control plane. PIC is a module which has physical ports to connect, and it can be built-in or modular, depending on the type of card you are using. In this series, we will mostly focus on control plane data collection commands for various protocols or technologies. I might not be able to cover all the protocols or technologies, but I will try to cover basic things which can help you with day to day operations and verification. In this specific post, I will cover all the basic commands that you need to verify health check related information and basic routing information. Show commands can be executed from any level of router mode.

Example: Create and Apply Configuration Groups. Example: Disable Inheritance of a Configuration Group. Example: Use the junos-defaults Configuration Group. Example: Use Wildcards with Configuration Groups. Use configuration groups to set up and apply common elements that are reused within the same configuration. The same group can be applied to different sections of the configuration. Configuration groups enable you to create smaller, more logically constructed configuration files, making it easier to configure and maintain Juniper Networks devices. For example, you can group statements that are repeated in many places in the configuration, such as when configuring interfaces. By grouping statements, you can limit configuration updates to just the group. You can also use wildcards in a configuration group.

World TIME. My plan is to go over configurations in the next couple of posts. When you issue the show configuration command with the display set pipe option to view the configuration as set commands, those portions of the configuration that you do not have permissions to view are substituted with the text ACCESS-DENIED.

Display the set commands from the configuration at the [ edit interfaces ] hierarchy level:. The number actually goes up to , but I find it easier to type How would you go about doing this? If you want to replicate the configuration on a new interface, this one command will do the trick:. When this happens, there are often large sections of the config that you rarely, if ever, care about. The 'show firewall log' command displays entries in the memory-resident buffer or kernel cache. The router stores information in this buffer when the log filter action is used. Example: Display the Current Configuration The following example shows how you can display the current device configuration. Desktop environment. You can view a list like this:.
