Description
Advanced Encryption and Authentication features
The Cisco 3925E SRE Bundle (C3925E-VSEC-SRE/K9) offers advanced encryption and authentication features to help secure networks and remote users. These features include:
- Advanced Encryption Standard (AES) and Secure Hash Algorithm (SHA) encryption: The router supports AES and SHA encryption algorithms, which provide strong encryption for data in transit.
- Internet Key Exchange version 2 (IKEv2): The router supports IKEv2, which allows for secure key management and negotiation for VPN connections.
- Secure Sockets Layer (SSL) and Transport Layer Security (TLS) encryption: The router supports SSL and TLS encryption protocols, which are commonly used to secure web-based applications and services.
- Public Key Infrastructure (PKI) support: The router supports PKI, which allows for secure certificate-based authentication and encryption.
- Two-factor authentication: The router supports two-factor authentication, which requires users to provide two forms of identification, such as a password and a security token, to gain access to network resources.
- Extensible Authentication Protocol (EAP) support: The router supports EAP, which allows for secure authentication of wireless clients.
- Access Control Lists (ACLs): The router supports ACLs, which allow network administrators to control access to network resources based on user or device attributes.
- Cisco Identity Services Engine (ISE): The router supports the ISE, which is a network access control solution that provides network access security and security posture assessment.
- Cisco Firepower NGFW: The router supports the Cisco Firepower NGFW, which is a next-generation firewall that provides advanced threat protection and application visibility.
These advanced encryption and authentication features allow the C3925E-VSEC-SRE/K9 to provide a high level of security for networks and remote users, while also enabling secure and reliable remote access. The SRE 900, PVDM3-64, UC also add more security features as it provides integrated security features such as firewall, VPN, intrusion prevention, and advanced malware protection.
Service and Performance enhancements of SRE 900
The Cisco 3925E SRE Bundle with SRE 900, PVDM3-64, and UC (C3925E-VSEC-SRE/K9) offers a range of service and performance enhancements that help to improve network efficiency and reliability. Some of these features include:
- Security and VPN capabilities: The C3925E-VSEC-SRE/K9 includes the SRE 900 security services module, which provides advanced security and VPN capabilities to help protect networks and remote users from cyber threats.
- Quality of Service (QoS): The router supports a variety of QoS features, such as traffic shaping and prioritization, which help to ensure that critical network traffic is given priority over non-critical traffic.
- Power over Ethernet (PoE): The C3925E-VSEC-SRE/K9 supports PoE, which allows it to power devices such as IP phones and wireless access points over the same Ethernet cable used for data transfer.
- Voice over IP (VoIP) support: The router includes a PVDM3-64 voice and video DSP module, which allows it to support up to 64 voice or fax sessions, helping to improve call quality and reliability.
- Unified Communications (UC) support: The router supports UC, which allows it to integrate with other Cisco UC products, such as Cisco Unity Express, Cisco Unified Presence, and Cisco Unified Communications Manager, to provide a comprehensive communication solution.
- High-Performance: The router is built on the Cisco 3900 series platform which supports high-performance network services and applications, it can handle high data traffic and fast speed.
- High-Availability: The router includes features such as hot-swappable power supplies and fans, which help to ensure that the router remains operational even in the event of a hardware failure.
These service and performance enhancements allow the C3925E-VSEC-SRE/K9 to improve network efficiency and reliability, while also providing a high level of security and voice and video capabilities for organizations.
Quality of Service (QoS) and Traffic Management
The Cisco 3925E SRE Bundle, SRE 900, PVDM3-64, UC (C3925E-VSEC-SRE/K9) offers advanced Quality of Service (QoS) and traffic management capabilities to help ensure that critical network traffic is prioritized and delivered efficiently. These features include:
- Class-Based Weighted Fair Queuing (CBWFQ): CBWFQ allows network administrators to assign different levels of priority to different types of traffic, such as voice, video, and data.
- Low Latency Queuing (LLQ): LLQ prioritizes delay-sensitive traffic, such as voice and video, to ensure that these types of traffic are delivered with minimal delay.
- Weighted Random Early Detection (WRED): WRED helps prevent network congestion by randomly dropping lower-priority traffic before the network becomes overwhelmed.
- Multi-Field Classifier (MFC): MFC allows network administrators to classify traffic based on multiple fields, such as IP address, port number, and protocol.
- Quality of Service (QoS) policies: The router supports QoS policies, which allow network administrators to define rules that dictate how different types of traffic are handled.
- Traffic shaping: The router supports traffic shaping, which allows network administrators to control the rate at which traffic is sent, helping to prevent network congestion.
- Policing: The router supports policing, which allows network administrators to set limits on the amount of traffic that can be sent or received by a device or user.
These advanced QoS and traffic management features allow the C3925E-VSEC-SRE/K9 to provide a high level of service for mission-critical applications such as Voice over IP, video conferencing, and streaming services.
