Features and Benefits Gained by Using Arista 720XP Switches

Advanced Monitoring: A key functionality on which Arista focused during the development of the 720XP is network-wide visibility and advanced network monitoring. Other key functionalities related to this feature include:

  • Latency Analyzer and Microburst Detection (LANZ): LANZ is a set of features made available by EOS that provides network-wide visibility into areas where packets experience delays. Network administrators can then take advantage of this information to decrease latency and speed service delivery.

  • Zero Touch Provisioning (ZTP): This is a process where a switch on the network is configurable or updated without human intervention.

  • Integrated packet capture and analysis with TCPDump: The 720XP integrates with TCPDump, which is used to capture and examine data packets.

  • Advanced Mirroring-Port Mirroring (16 sessions): Port mirroring is a process where one switch sends a copy of the data packets on its port to the port of a monitoring switch on the network. It is divided into:
    • Enhanced Remote Port Mirroring
    • Port Mirroring (4 active sessions)
    • L2/3/4 Filtering on Mirror Sessions

  • Software Defined Networking (SDN): This is a network architecture technique that involves the central control of the network using software applications. The following controllers can be used for the Arista 720XP switch:
    • Openflow 1.0
    • Openflow 1.3
    • Arista DirectFlow
    • eAPI
    • OpenStack Neutron Support

  • Advanced Event Management Suite (AEM):
    • CLI Scheduler
    • Event Manager
    • Event Monitor
    • Linux tools

Other equally important monitoring and control features available with the 720XP include:

  • Configurable Congestion Notification (CLI, Syslog)
  • Streaming of Events (GPB Encoded)
  • Capture/Mirror of congested traffic
  • FlowTracker features
  • RFC 3176 sFlow
  • IPFIX support
  • Restore and configure from USB
  • EEE 1588 PTP (Transparent Clock and Boundary Clock)

Real-Time Telemetry: 720XP’s cognitive flow tracker feature works with EOS’s Cognitive Management Plane function to ensure access to real-time telemetry of devices, users, and application workflows.

The flow tracker allows network operators to assess network health and performance by tracking key measurements without interrupting operations. In addition, the user won’t be limited to only using Arista’s network monitoring options - Flow Tracker has open APIs that support a host of third-party monitoring and security applications.

Advanced security: Another one of Arista’s main points of focus, while designing the 720 XP, was to ensure that users benefited from best-in-class security features. This set of functionalities is comprised of:

  • Service Access Control List (ACL): ACLs regulate access to network resources. An ACL is a list of rules that determine whether an end user or system on the network permits or denies access to a service.

  • Packet Data Protocol (PDP).

  • Control Plane Protection (CPP) ensures the control plane is secure.

  • MAC ACLs filter traffic on specific MAC addresses. Filtering prevents access to malicious content while permitting access to pertinent information.

  • 1X Enhancements, which can be further classified as:
    • Multi-Host 802.1X AUTH enables the authentication of multiple hosts that share a port.
    • MAC-Based AUTH (MAB): MAB is an access control strategy that uses a host’s MAC address to support access control on different ports.
    • Dynamic VLAN assignment.
    • Named VLAN support.

Other equally important security features include:

  • ACL Deny Logging
  • ACL Counters
  • Atomic ACL Hitless restart
  • DHCP Relay

  • Remote Authentication Dial-In User Service (RADIUS)
  • ARP trapping and rate limiting.

This host of network access management features positions the 720XP as one of the market's most secure Wi-Fi and switching platforms.

Scalability: The uniquely designed 720XP series can work with many programs and applications.

Arista EOS: Arista's single binary EOS powers these platforms that transmit telemetry data to other Arista offerings, such as CloudVision, enabling users to visualize and analyze data in real time. With this powerful operating system, the 720XP series provides cloud-grade Layer 2 switching, Layer 3 routing, and virtualization services.

Additionally, EOS has open APIs that support automation of crucial network operations, such as configuration, software lifecycle management, and maintenance using either Arista's CloudVision or any other third-party solution.

Dynamic Traffic Load Balancing: With the 720XP series, users can implement either the L2 MLAG or L3 ECMP load-balancing schemes to ensure high availability load sharing and traffic prioritization. Arista’s integrated Dynamic Load Balancing (DLB) feature is integral to other infrastructure on a campus network, which helps to improve overall performance.

CloudVision: Arista CloudVision is a central management platform that automates and simplifies network lifecycle operations throughout the campus, data center, Wi-Fi, and multi-cloud.

The management plane supports automated provisioning, continuous compliance, change control, predictive analytics, and real-time telemetry. In addition, CloudVision can be integrated with most third-party management platforms.

CloudVision is, in every sense, an affordable multi-domain solution that increases efficiency and speeds up the setup of a new branch on the network. Arista offers CloudVision either as-a-service or as a virtual/physical on-premises appliance.

Campus Segmentation: The 720XP series switches offer overlay segmentation services that allow users to separate the traffic of individual users into their own VLANs. The purpose of segmentation is to reinforce data and infrastructure security.

Automatic processes for allowed users are activated when they have predetermined 802.1Q or EVPN VXLAN segmented networks allocated to them.

They segment the most sophisticated cases on the campus, using wire-speed Layer 3 Virtual Routing and Forwarding (VRF) segmentation. Finally, these switches assist administrators in Wi-Fi segmentation by de-encapsulating tunneled Wi-Fi traffic.
