Juniper MX80-48T Introduction
The document provides an overview of the Juniper MX80-48T router, including its specifications and features. It is described as a low-end edge router with a system capacity of 80Gbps and 1 service module slot. Key specifications listed include a 2RU size, 55Mpps throughput, and redundancy for fans and power. Hardware details are provided on its built-in interfaces of 48 1GE ports and 4 10GE ports. Differences from other MX routers are also summarized.
Juniper MX80 Introduction
This document provides an overview of the Juniper MX80 router, including its specifications and components. The MX80 is a low-end edge router with a system capacity of 80Gbps. It has 3 MIC slots and can support up to 8 10G ports and 40 1G ports. Redundancy is provided for fans and power supplies. The MX80 uses MIC modules to provide interfaces and features like IPsec, NAT, traffic sampling, firewalling and attack protection.
Mastering JUNOS Syslog
The document discusses syslog logging on JUNOS devices, including logging normal and abnormal events, the different syslog categories or facilities like kernel, user, daemon, and security, the syslog severity levels from emergency to info, and how to configure syslog logging locally to files, remotely to syslog hosts, and to display messages on the console.

The document discusses syslog logging on JUNOS devices, including logging normal and abnormal events, the different syslog categories or facilities like kernel, user, daemon, and firewall filter, the syslog severity levels from emergency to info, and examples of syslog configurations for logging locally to a file, remotely to a host, and to the console.
Mastering JUNOS DHCP
DHCP allows clients to obtain IP addresses and other network configuration parameters automatically from a DHCP server. The document outlines DHCP server configuration commands to define an interface, address pool, and range of addresses to assign to clients, as well as a DHCP client configuration command to automatically obtain an IP address from the server on the ge-0/0/2.0 interface.

Mastering JUNOS DNS
DNS allows devices to use hostnames instead of IP addresses by resolving names to IP addresses. There are two ways for DNS setting - on-device name resolution which does not use DNS servers and resolves names locally, or off-device name resolution which uses external DNS servers. Commands like set system static-host-mapping and set system name-server can configure the DNS settings and map hostnames to IP addresses either locally or through DNS servers.

Remote access to the system is disabled by default but can be enabled by setting system services for Telnet, SSH, and FTP which allow connections from external locations.
マスタリングJUNOS 編集コマンド
The document describes various Juniper configuration editing commands:
- The copy command copies configuration settings from one interface to another.
- The rename command changes the name of a configured interface.
- The replace command performs a pattern match and replace on configuration settings.
- The insert command moves configuration statements within a block up or down.
- The deactivate/activate commands disable and re-enable interface configurations.
Mastering JUNOS commit
The commit command in Junos saves the current active configuration and stores up to the last 50 configurations. The active configuration and last 3 are stored in /config, while the remaining 46 are stored in /var/db/config. The commit command has additional options like and-quit to move to operational mode after committing, check to validate configurations, comment to add comments, at to set a time to commit, and confirmed to automatically roll back the previous configuration.
マスタリングJUNOS commit
This document discusses the commit command in Juniper devices, which applies configuration changes and saves them to be active. It saves up to 50 generations of past configurations, with the most recent in /config and older ones in /var/db/config. The commit command can check configurations, add comments, commit at a scheduled time, and confirm commits or cancel scheduled commits.
Mastering JUNOS JUNOS CLI Modes
There are three CLI modes - shell, operational, and configuration. Operational mode is used to verify device status like hardware status and interface information. Configuration mode is used to configure devices using commands like set, delete, and commit. Modes can be switched between using commands like start shell, cli, configure, and exit depending on the user's privileges.
Network Protocol Spelunker LLDP-Link Layer Discovery Protocol-
This document provides an overview of the Link Layer Discovery Protocol (LLDP) including its purpose, packet format, and configuration on Cisco IOS and Juniper JUNOS. LLDP is an open standard protocol that allows devices to advertise information about themselves to neighboring devices. This includes chassis ID, port ID, system description and other details. The document reviews LLDP configuration, monitoring, and troubleshooting commands for Cisco IOS and Juniper JUNOS. It also includes examples of LLDP implementation on Cisco and Juniper routers to share interface and network information between connected devices.
