Starting 8.8 release, Cloud customers can receive all events/alerts as SNMP traps. While configuring an SNMP trap

The Software Management Studio is used to manage EOS images and extensions and assign them to devices. You’ll use the studio’s Software Repository to upload EOS images, Streaming Agents, and extensions. You’ll then  assign software from the Software Repository to devices using a new or open workspace.

Source ARP with a virtual IP is a new VARP feature. The purpose of this feature is to change the ARP request header's sender IP and sender MAC address to the virtual IP and virtual MAC addresses. This change occurs for all the ARP request packets originating from the router that match a configured virtual subnet.

With the 13.0 release, you can enable spatial reuse from CloudVision Cognitive Unified Edge (CV-CUE) to improve the spectral efficiency and optimally allocate resources to meet the Quality of Service (QoS). With spatial reuse, two or more Wi-Fi devices (AP or client) that support 802.11ax protocols can send transmissions simultaneously without any significant data loss.

Spectrum analysis is a tool to analyze the RF environment for interference. For monitoring and troubleshooting of wireless networks, you must be aware of the RF environment in which the  APs operate.

This document describes the support for performing SSH authentication with X.509 certificates. Authentication to SSH can be completed using a number of different methods. Public key, password and keyboard interactive are supported in EOS. Certificate login is a type of public key authentication in which the public key does not have to be stored on the server. Instead trusted certificate authorities are installed. A presented certificate must be signed either directly or indirectly by one of these trusted certificate authorities to allow authentication to the device. Support for OpenSSH certificates (also known as SSH Certificates) was added in 4.22.1F.

This is an infrastructure that provides management of SSL certificates, keys and profiles. SSL/TLS is an application-layer protocol that provides secure transport between client and server through a combination of authentication, encryption and data integrity. SSL/TLS uses certificates and private-public key pairs to provide this security.

Before this feature was introduced, any daemon agent needing to interface with Sysdb for configuration retrieval and status updates had to go through the agent manager within the EOS SDK. Usage of the EOS SDK introduced various ABI issues due to constraints on which compiler, libc and kernel versions the daemon must be built with. This feature offers an alternative mechanism via gRPC, providing more flexibility in how daemon executables are built and used to programmatically interact with and monitor the EOS device.

Static ARP inspection is a security feature that verifies the source IP and the source MAC addresses of each received

The Static Configuration Studio is used to manage static configuration for devices, provide configuration not created by any other studio, and reconcile differences between CloudVision’s designed configuration and device running configuration. Devices are assigned to containers using tags that can identify one or more devices by hostname, role, or location in the network. Each container has configlets of EOS configuration, which are pushed to the EOS devices.

The existing storm control interface configuration mode CLI commands have been extended to support the new

A traffic storm is a flood of packets entering a network, resulting in excessive traffic and degraded performance. Storm control prevents network disruptions by limiting traffic beyond specified thresholds on individual physical LAN interfaces. Storm control monitors inbound traffic levels over one-second intervals and compares the traffic level with a specified benchmark. The storm-control command configures and enables storm control on the configuration mode physical interface.

A traffic storm is a flood of packets entering a network, resulting in excessive traffic and degraded performance.

This feature introduces a new type of action that can be created and configured under Provisioning > Actions. These actions automate the process of assigning values to inputs in a studio and allow users to input data that originates from outside a studio.

These updates improve the layout of the Studios landing page by emphasizing essential studios and structuring all other studios in a more comprehensive, user-friendly way.

This feature enables ACL functionality on subinterfaces. ACLs on subinterfaces are configured using the

Subinterfaces are logical L3 interfaces that enable the division of a single Ethernet or Port channel interface into

The guaranteed bandwidth feature ensures minimum bandwidth for outgoing lower priority traffic from a

This feature adds support for configurable max sFlow datagram size. The current default max datagram size is 1400 bytes, which can cause some sFlow datagrams to be dropped when there is an MTU set. This feature enables the configuration of the max datagram payload size within the range of 200 to 1500 bytes to help avoid fragmentation. Note that this feature only configures software sFlow and is not supported on hardware-accelerated sFlow.

This feature adds support for CPU traffic policy capable of matching and acting on IP traffic which would otherwise

Prior to 4.32.2F, the “reset system storage secure” CLI command can be used to perform a best-effort storage device wipe of all sensitive data. However, this command has the limitation that it wipes EOS from the storage device, leaving the system “stuck” in Aboot. The “reset system storage secure rollback” command provides the same secure erase functionality, but additionally allows the user to preserve a subset of files on the main flash device by copying them into RAM during the secure erase procedure. The set of files that are preserved is configurable. After a successful wipe, the system will return to EOS after the erase is complete if the EOS SWI image and adequate configuration files are preserved (such as boot-config and startup-config).

IS-IS SR Stateful Switchover (SSO) support allows for a switchover from an active supervisor to a standby supervisor where MPLS traffic remains undisrupted during switchover. This involves reconciliation of all Segment Routing related information in the network using IS-IS Graceful Restart procedures. And also installing the same in forwarding hardware in a manner that does not disrupt the ongoing traffic.

This feature enables the user to configure PBR policy on an interface in any VRF, to match and forward incoming packets

In order to support PIM/IPv4 multicast routing on EOS switches with Broadcom Tomahawk4 ASICs, multicast support using ALPM is required. This works in both 3-level Algorithmic Longest Prefix Match (ALPM) capabilities and 2-level ALPM.

This document describes the availability of VLAN ingress and egress counters on R Series platforms. VLAN counters provide the ability to count packets and bytes ingressing or egressing a bridge domain (VLAN).

VXLAN tunneling requires that the switch where the tunnel terminates is configured with a VTEP that matches the configuration on the AP. CV-CUE now provides an easier way to match configurations on both AP and the switch. By having the same VXLAN configuration for access points (APs) and switches, you can aggregate all wireless traffic from the same VXLAN to a single wired destination for better traffic management and visibility.

As a result of upgrading the Debian distribution to Bookworm, the original Python CLI (based on python2) was removed, as the interaction with the DANZ Monitoring Fabric (DMF) and CCF is performed mainly from the Controller. However, several customer operations involve some of the commands used on the switch. These commands are implemented in the new CLI (based on python3) in Switchlight in the Bookworm Debian distribution.

For modular systems operating under the SSO redundancy policy, if  the system database agent (Sysdb) on the

With the 13.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces system backup and restore capability. You can back up the entire system or only the configuration files, and restore them when needed.
