CloudVision allows users to monitor a device’s environment by displaying graphs for temperature, power supply and fan speed. Power Supply shows the power used at each power socket on the device. Previously users could only view a visualization of output power. A visualization for input power is now available to view.

With the 12.0 release, you can configure DHCP fingerprinting to allow or deny clients getting connected to an SSID. Using DHCP fingerprinting, you can identify the operating system (OS) of the client based on the DHCP exchange packets between the client and the DHCP server.

ECMP Hash visibility CLI determines the output interface for an ECMP set based on the flow parameters supplied by the user. Ingress interface, source IP address, destination IP address and IP protocol are the required parameters. L4 source and destination ports and VLAN identifier are optional, but should be specified if the packet has them.

This feature provides the capability to count the number of packets hitting rules associated to egress ACLs applied

Egress ACL deny logging on Arista DCS 7280E, DCS 7500 and DCS 7500E series switches allows the logging of the

The feature allows to create a named TC to DSCP mapping that can be applied on an interface.DSCP of routed packets egressing out of the interface will be rewritten according to the map.

IPv4/IPv6 over MPLS packets are now eligible for ACLs at egress stage by default. The feature is applicable only to

Event Rollup allows you to manage the volume of identical events and can be used to flag when an event is recurring. Event Rollup groups together events that are identical except for their timestamps. It does so in two ways: dynamically via the Event List and according to a 24-hour window via the detailed event view. It can be enabled or disabled at will, using the Roll Up toggle.

In order to minimize the volume of change control events, CloudVision has introduced a new event, Change Control Events. Change Control Events is generated when 2 or more of the following events are triggered for the same change control:

Ethernet VPN (EVPN) is an extension of the BGP protocol introducing a new address family: L2VPN (address family

In the traditional data center design, inter-subnet forwarding is provided by a centralized router, where traffic traverses across the network to a centralized routing node and back again to its final destination. In a large multi-tenant data center environment this operational model can lead to inefficient use of bandwidth and sub-optimal forwarding.

In EOS 4.22.0F, EVPN VXLAN all active multi homing L2 support is available. A customer edge (CE) device can connect to

EVPN gateway support for all-active (A-A) multihoming adds a new redundancy model to our multi-domain EVPN solution introduced in [1]. This deployment model introduces the concept of a WAN Interconnect Ethernet Segment identifier (WAN I-ESI). The WAN I-ESI allows the gateway’s EVPN neighbors to form L2 and L3 overlay ECMP on routes re-exported by the gateways. The identifier is shared by gateway nodes within the same domain (site) and set in MAC-IP routes that cross domain boundaries.

This enhancement is to display the number of packets that were ECN (Explicit Congestion Notification) marked by the

Use an External Certification Authority (ECA) to ensure secure communication and authentication with CloudVision..By default, Streaming Agent and other applications communicate with CloudVision using mutual-TLS certificates signed by a local certificate authority (CA). You now have the option to integrate CloudVision with Venafi,  an external CA, to sign and verify these certificates.

FIPS is a US federal standard for computer systems and data security that mandates only compliant cryptographic algorithms and their implementations be used in a product’s cryptographic operations. A product is considered FIPS compliant if it uses verified crypto modules that have been certified by a laboratory approved by the National Institute of Standards and Technology (NIST). CloudVision has completed the FIPS certification process to allow users with both single-node and multi-node clusters to operate in FIPS mode. Intra-node communication is not yet certified and will follow in Phase 2.

In the 17.0 release, CV-CUE introduces FEED. FEED is a network dashboard that presents a timeline view of all the detected anomalies in the network. CV-CUE curates the FEED by continuously monitoring and proactively detecting anomalies in the network. It also analyzes the cause of the anomaly and provides dynamic suggestions to mitigate the issue. The administrator can analyze the issue, the AI-based recommended action, and then decide on the best approach to mitigate the issue. Feed also lets administrators go back in time and understand anomalies that occurred in the past.

Organizations may have multiple access points (APs) of different models operating with various firmware versions. As an organization, you may want to designate a specific version as a compliant firmware version for a certain model. Assigning a compliant firmware version helps network administrators identify non-compliant AP models by generating notification alerts.
