Backing Up and Restoring the Configuration File Using a Remote Server

Note We recommend copying the current configuration file to a remote server before upgrading.

Use the copy [/erase] source_url destination_url keyword command to copy the configuration file to a remote server. You can then restore the current configuration from the remote server. You are prompted to back up the current configuration first. The following options apply:

•/erase—Erases the destination file before copying.

This keyword only applies to the current-config; the backup-config is always overwritten. If this keyword is specified for destination current-config, the source configuration is applied to the system default configuration. If it is not specified for the destination current-config, the source configuration is merged with the current-config.

•source_url—The location of the source file to be copied. It can be a URL or keyword.

•destination_url—The location of the destination file to be copied. It can be a URL or a keyword.

•current-config—The current running configuration. The configuration becomes persistent as the commands are entered.

•backup-config—The storage location for the configuration backup.

The exact format of the source and destination URLs varies according to the file. Here are the valid types:

•ftp:—Source or destination URL for an FTP network server. The syntax for this prefix is: ftp:[//[username@] location]/relativeDirectory]/filename ftp:[//[username@]location]//absoluteDirectory]/filename

•scp:—Source or destination URL for the SCP network server. The syntax for this prefix is: scp:[//[username@] location]/relativeDirectory]/filename

scp:[//[username@] location]//absoluteDirectory]/filename

Note If you use FTP or SCP protocol, you are prompted for a password. If you use SCP protocol, you must also add the remote host to the SSH known hosts list.

•http:—Source URL for the web server. The syntax for this prefix is: http:[[/[username@]location]/directory]/filename

•https:—Source URL for the web server. The syntax for this prefix is: https:[[/[username@]location]/directory]/filename

Note HTTP and HTTPS prompt for a password if a username is required to access the website. If you use HTTPS protocol, the remote host must be a TLS trusted host.

IPS4520K9 specifications

Cisco Systems has long been a leading player in network security, and its IPS (Intrusion Prevention System) series is a testament to its commitment to safeguarding digital environments. Among its notable offerings are the IPS4510K9 and IPS4520K9 models, both designed to provide advanced threat protection for mid-sized to large enterprise networks.

The Cisco IPS4510K9 and IPS4520K9 are distinguished by their cutting-edge features that help organizations defend against a myriad of cyber threats. These systems utilize a multi-layered approach to security, integrating intrusion prevention, advanced malware protection, and comprehensive visibility across the network.

One of the primary characteristics of the IPS4510K9 is its high performance. It boasts a throughput of up to 1 Gbps, making it suitable for environments that demand rapid data processing and real-time responses to threats. The IPS4520K9, on the other hand, enhances that capability with improved throughput of up to 2 Gbps, accommodating larger enterprises with heavier network traffic. These models are equipped with powerful processors that support complex signature matching and can intelligently distinguish between legitimate traffic and potential threats.

In addition to performance, both models are designed with scalability in mind. They can be easily integrated into existing Cisco infrastructures. This facilitates a seamless enhancement of security without causing significant interruptions to ongoing operations. Moreover, they offer flexible deployment options, allowing organizations to operate them inline or out of band depending on their specific needs.

The Cisco IPS4510K9 and IPS4520K9 leverage advanced detection technologies, utilizing a variety of signature types and heuristic analysis to detect known and unknown threats effectively. They are equipped with real-time alerting and reporting capabilities, giving security teams immediate visibility into potential breaches and enabling them to respond swiftly.

Furthermore, both models support a range of management options through the Cisco Security Manager, allowing for centralized administration, streamlined policy management, and enhanced monitoring capabilities. Automated updates ensure the systems remain current with the latest threat intelligence, vital for staying ahead of evolving cyber threats.

In summary, the Cisco Systems IPS4510K9 and IPS4520K9 represent powerful solutions for organizations seeking robust intrusion prevention capabilities. With their high performance, scalability, and advanced detection technologies, these systems are essential tools in the ever-changing landscape of cybersecurity, providing enterprises with the peace of mind needed to operate securely in today's digital world.
