Course Overview
Students Industrial Work Experience Scheme (SIWES) Agboko B.A
The Junos OS1. Robust, modular operating system2. Base on the FreeBSD Unix operating system(the kernel is based on the FREEBSD UNIX operating system, which is an open source software system)
Students Industrial Work Experience Scheme (SIWES) Agboko B.A
Single software Train1. A single software train for all platforms running the
junos OS2. Eases management overhead by providing a consistent
set of features that are implemented in a consistent manner

1. The processes that control routing and switching protocols are clearly separated from the processes that forward frames, packets through the device running the junos OS
2. The RE is the brain of the platform: its responsible for performing protocol updates and system management
3. The RE maintains the routing table, bridge table and primary forwarding table and connects to the packet forwarding engine (PTE) through the internal link.
4. This architectural design also makes possible the incorporation of high availability features like graceful routing engine switchover (GRES), nonstop active routing (NSR) and unified in-service software updates (ISSUs)

1. Maintain Routing engine intelligence2. Controls and monitors the chassis3. Manages Packet Forwarding Engine The RE controls the PFE by providing accurate up-to-date layer2 and layer3 forwarding table

1. Operational modein operational mode, you use the CLI to monitor and troubleshoot the device. The monitor, ping, show, test, and tracroute commands lets you display information and test network connectivity for the device.
2. Configuration modein configuration mode, you can configure all the properties of the Junos device including interfaces, protocols, and user access as well as several hardware properties

CLI Basics
Students Industrial Work Experience Scheme (SIWES) Agboko B.A
Ways of accessing help within the CLI
1. Type ? Any wherr on the CLI to get help (e.g>> ?)2. Help topic “key word” ? (e.g >>help topic interfaces ?)3. Help with configuration syntax
(e.g>>help reference interfaces address)3. Command and variable completion (e.g>> sh<spacebar>ow i<space>4. Using the tab key for variable completion5. Using | (Pipe): use | to filter and manipulate command output
(e.g>>show route | ?)6. And many more…
