Feature description MSS-G or Group-Based Segmentation Security is a security feature that allows users to classify endpoints into segments and define forwarding policies between segments. A given segment contains a set of endpoints that should have identical security properties within the network. Policies are then defined between segments rather than between endpoints, and EOS devices enforce the specified policies in hardware. EOS shipped MSS-G support in 4.25. CVP on-prem support will ship in 2021.2 and requires EOS 4.26.1 or later with a minimum TerminAttr version of 1.16.2. It will also be supported in CVaaS. This support includes a way to...

DHCP Endpoints in Address Search

This is an expansion of the ‘Endpoint Search’ feature introduced in the Howard Release. For more information on what Endpoint Search is and how to access it, refer to the previous TOI on ‘Endpoint Search’. Searching for DHCP Endpoints This add-on to the Endpoint Search feature can be seen when a user searches for a DHCP device name or a MAC address associated with a DHCP device. A search for the DHCP endpoint can also be accomplished by clicking on one of the MAC Address links to Address Search in the Connected Endpoints table. DHCP devices can be found in...

Service Accounts (Beta)

Overview Service accounts allow access to our APIs in a controlled manner from CloudVision. Authentication tokens can be created for service accounts that allow authentication to our APIs. A Service Account is essentially a user, except that instead of logging in, we generate credentials for the service account. The service account token credential authenticates a connection as a service account. Usage The token can be used to authenticate any connection to the apiserver, that is: HTTPS/REST, websocket, and GRPC. For websocket/REST APIs, attach the token as a cookie or using the Authorization header. Examples: curl -b access_token=${TOKEN} ... curl -H...

TapAgg support on MACsec linecards

Introduction Media Access Control Security (MACsec) is an industry standard security technology that provides secure communication for all traffic on Ethernet links. As of EOS 4.20.5F for Arista 7500 lines of switches, users of the tap aggregation features can benefit from using MacSec on tap/tool ports on MacSec capable line cards. Users can use MACsec to secure the communications between their tap/tool ports and ports from other switches which may not necessary be a TapAgg equipment. Enabling MACsec on a port puts it into an “unauthorized” state. Then the interface will not be forwarding any traffic until the MACsec peers successfully complete the MACsec Key Agreement (MKA) procedures. Once...

EVPN IRB with Vxlan Underlay

EVPN Integrated Routing and Bridging (IRB) with VXLAN In the traditional data center design, inter-subnet forwarding is provided by a centralised router, where traffic traverses across the network to a centralised 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.   To provide a more optimal forwarding model and avoid traffic tromboning, the EVPN inter-subnet draft (draft-sajassi-l2vpn-evpn-inter-subnet-forwarding) proposes integrating the routing and bridging (IRB) functionality directly onto the VTEP, thereby allowing the routing operation to occur as close to the...

MP BGP for v4 multicast

Introduction The feature MP-BGP Multicast provides a way to populate the MRIB (Multicast Routing Information Base). MRIB is an alternate routing table used in PIM’s RPF (Reverse Path Forwarding) lookup. Up until now, there was only one way to populate the routes in the MRIB. Users can add a static route into the MRIB via the ip mroute or rpf route command under router multicast ipv4 or ipv6. With BGP support for multicast SAFI, users can advertise multicast static routes and connected routes to other PIM routers. These routes learned via BGP are stored in the MRIB.   While selecting...

Unidirectional links

Unidirectional links is a feature that configures an Ethernet interface transmit and receive paths to be independent. Specifically, the transmit path can be up or down independent of the receive path being up or down.
