•For the procedure for configuring the physical interface settings, see Configuring Physical Interfaces, page 4-11.

•For the procedures for creating and deleting different kinds of interfaces, see Configuring Inline Interface Mode, page 4-16, Configuring Inline VLAN Pair Mode, page 4-21, Configuring VLAN Group Mode, page 4-26, and Configuring Inline Bypass Mode, page 4-33.

Configuring Physical Interfaces

Use the physical-interfacesinterface_name command in the service interface submode to configure promiscuous interfaces. The interface name is FastEthernet, GigabitEthernet, or PortChannel.

Note You configure the ASA IPS modules (ASA 5500-X IPS SSP and ASA 5585-X IPS SSP) for promiscuous mode from the adaptive security appliance CLI and not from the Cisco IPS CLI.

The following options apply:

•admin-state {enabled disabled}—Specifies the administrative link state of the interface, whether the interface is enabled or disabled.

Note On all backplane sensing interfaces on all modules, admin-stateis set to enabled and is protected (you cannot change the setting). The admin-statehas no effect (and is protected) on the command and control interface. It only affects sensing interfaces. The command and control interface does not need to be enabled because it cannot be monitored.

•alt-tcp-reset-interface—Sends TCP resets out an alternate interface when this interface is used for promiscuous monitoring and the reset action is triggered by a signature firing.

Note You can only assign a sensing interface as an alternate TCP reset interface. You cannot configure the management interface as an alternate TCP reset interface.

Note There is only one sensing interface on the ASA IPS modules (ASA 5500-X IPS SSP and

ASA 5585-X IPS SSP), so you cannot designate an alternate TCP reset interface.

–interface_name—Specifies the name of the interface on which TCP resets should be sent when this interface is used for promiscuous monitoring and the reset action is triggered by a signature firing. This setting is ignored when this interface is a member of an inline interface.

–none —Disables the use of an alternate TCP reset interface. TCP resets triggered by the reset action when in promiscuous mode will be sent out of this interface instead.

•default—Sets the value back to the system default setting.

•description—Specifies your description of the promiscuous interface.

IPS4510K9 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.
