My Network Lab: Juniper Networks Monitoring and System Maintenance

Juniper delivers advanced security requirements with the SRX Series Services Gateways. These next-generation firewalls adapt as new threats emerge. They use information from the Juniper Advanced Threat Prevention cloud-based service and third-party GeoIP feeds to block malicious activities as they enter or traverse the network.

Monitoring System Operation

You can monitor most system related information using the show system <ARGUMENT> commands.

Packet Capture

The Junos OS monitor traffic command allows packet capture using the tcpdump utility. It monitores traffic to or from the local Routing Engine (RE). The management interface is chosen and monitored if there's no interface specified. Use the Ctrl+c keys to stop the capture.

The Junos OS naming convention format is <package>-<release>-<edition>

package - is the description of the software contents. Ensure to download and install the appropriate image for your device/platform.

jinstall is used on M, T and MX series

jinstall-ex is used on EX series

junos-jsr is used on J series

junos-srx is used on SRX series

release - describes the Junos OS Release. It includes two integers: major and minor release numbers.

R stands for released software

B stands for beta-level or testing software

I stands for internal, test or experimental software

S is reserved for service release

edition - either domestic or export. Domestic version support strong encryption while export do not.

Upgrading the Junos OS

It's good practice to initially check the device storage capacity using the show system storage command before downloading the new Junos OS image . You store the new Junos OS image in the /var/tmp directory.

You ucan se the request system software add <path/image-name> command to perform the Junos OS upgrade. You must reboot the system for the new software to take effect using the request system reboot as a separate step or adding the reboot option at the end of the request system software add <path/image-name> command.

It's recommended to monitor the upgrade process and watch for errors via the console.

Unified In-Service Software Upgrade (ISSU)

The Unified In-Service Software Upgrade (ISSU) feature allows you to upgrade a Junos OS in a dual Routing Engine (RE) with no disruption on the control plane. The Graceful Routing Engine Switchover (GRES) and Nonstop Active Routing (NSR) must be both enabled. The Master RE and Backup RE must run the same software before performing a unified ISSU. You can't take out any Physical Interface Card (PIC) online or offline when performing a unified ISSU.

The following are the steps in performing a Unified ISSU:

Enable GRES and NSR and verify the Master RE, Backup RE and protocols are synchronized.
Download and transfer the new software package to the router.
Issue the request system software in-service-upgrade command on the Master RE.

Password Recovery

You can only perform a system password (root) only at the console port.

The following are the steps in performing a password recovery:

Reboot the system > press space bar when prompted > type boot -s to access single user mode
Enter recovery when prompted for recovery mode
Type configure > set system root-authentication plain-text-password > type the new root password
commit the change > exit and reboot the system
