Chapter 4 Configuring Interfaces

Configuring VLAN Group Mode

In the second variation, the two ports are configured as trunk ports, so they can carry multiple VLANs. In this configuration, the sensor bridges multiple VLANs between the two switches. Because multiple VLANs are carried over the inline interface pair, the VLANs can be divided into groups and each group can be assigned to a virtual sensor.

Configuring VLAN Groups

Use the physical-interfacesinterface_name command in the service interface submode to configure inline VLAN groups. The interface name is FastEthernet or GigabitEthernet.

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.

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

•description—Specifies the description of the interface.

•duplex—Specifies the duplex setting of the interface:

–auto—Sets the interface to auto negotiate duplex.

–full—Sets the interface to full duplex.

–half—Sets the interface to half duplex.

Note The duplex option is protected on all modules.

•no—Removes an entry or selection setting.

•speed—Specifies the speed setting of the interface:

–auto—Sets the interface to auto negotiate speed.

–10—Sets the interface to 10 MB (for TX interfaces only).

–100—Sets the interface to 100 MB (for TX interfaces only).

–1000—Sets the interface to 1 GB (for Gigabit interfaces only).

Note The speed option is protected on all modules.

•subinterface-type—Specifies that the interface is a subinterface and what type of subinterface is defined.

–vlan-group—Lets you define the subinterface as a VLAN group.

–none—Speechifies that no subinterfaces are defined.

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.
