Macro-Segmentation Service (MSS) for L3 Firewalls

Feature description Arista Macro Segmentation Service (MSS) is a service in CloudVision, which dynamically places a firewall (FW) in the path of traffic between devices attached to front panel ports on Arista switches, based on policies tagged by the user in the FW (using predetermined tags, configured on CVX). In a traditional L3 FW deployment, the gateway for endpoints in a subnet is hosted on the FW and configured as the default route on the endpoint. In this integration, the firewall can be a Layer-3 attached system to the network. MSS service that runs in CloudVision, uses APIs provided by...

Bgp Monitoring Protocol for Multi-agent Model

Description BGP Monitoring Protocol (BMP) allows a monitoring station to connect to a router and collect all of the BGP announcements received from the router’s BGP peers. The announcements are sent to the station in the form of BMP Route Monitoring messages generated from path information in the router’s BGP Adj-Rib-In tables. A BMP speaker may choose to send either pre-policy routes, post-policy routes, or both. BMP functionality is available with the single agent routing protocol model since EOS-4.21.1F as described here.  EOS 4.21.4F introduces support for BMP in the multi-agent routing protocol model. Platform compatibility This feature is available on...

Show Interfaces Transceiver Dom [ Thresholds ]

Description This new CLI command provides all the DOM ( Digital Optical Monitoring ) data of the transceiver for the operational port. The new CLI display command is  show interfaces transceiver dom, optionally, specific interfaces are requested using show interfaces ethernetX/X transceiver dom. In addition, to procure the threshold information of all the present DOM parameters, one can run show interfaces transceiver dom thresholds command and optionally, the information for specific interface is requested with  show interfaces ethernetX/X transceiver dom thresholds. Show Commands For show interfaces transceiver dom: At the top of the display, there is a legend describing the acronyms used...

Configurable virtual removal of pluggable transceivers

Description: The feature allows a simulated transceiver removal, without physically touching the module. This can be used for troubleshooting, when physical removal is inconvenient. The feature is configured with the CLI command "[no] transceiver diag simulate removed" in interface configuration mode.  The command takes effect immediately. Platform Compatibility: Supported on all platforms. Limitations: Supports only QSFP+, QSFP100, SFP+, SFP25, OSFP and CFP2 pluggable transceiver types.   Configuration: Configure virtual removal with the CLI interface command, “transceiver diag simulate removed”. In the case of QSFP, apply to the primary interface, …/1 (applying to a non-primary interface will have no effect. As long as virtual...

Static VRF Label Termination

Description Static VRF label termination can be enabled at the egress PE to provide pop and route behavior. It allows one-to-one mapping of MPLS label to a VRF. If an incoming MPLS packet matches such a route (top/outermost label == VRF label), the VRF label will be terminated/popped and the packet will be forwarded based on the inner payload. If the inner payload is IPv4 or IPv6, then lookup and forwarding will be carried out in the context of the specified VRF. This also works with PHP (the top/outermost label will be popped on the hop before the egress PE). If...

Redistribute dhcp support in ArBgp (IPv6)

Redistribute dhcp support in ArBgp (IPv6) Description This feature allows for redistributing DHCPv6 routes in Bgp in multi-agent routing protocol mode. Given below is the link to the TOI for this feature in ribd routing protocol mode: https://eos.arista.com/eos-4-20-1f/dhcpv6-pd

Propagating ECN header on Vxlan Encap/Decap

Description This feature allows the network administrator to set a flag to allow the Explicit Congestion Notification (ECN) headers of a packet be preserved and copied to inner or outer packets when the packet is decapsulated or encapsulated on a Vxlan Tunnel Endpoint (VTEP). The Explicit Congestion Notification (ECN) bits are two bits in the IP TOS header and can be used by the routers to note congestion in the network instead of dropping the packets. This behaviour is defined in RFC6040. When the transmitter receives a packet with ECN bits set, it will try to adjust its transmission rate...

SYSLOG based alerting on optical thresholds

Description Add the ability to generate SYSLOG messages when a transceiver’s digital optical monitoring threshold is crossed. Platform Compatibility All platforms that support optics with DOM. Configuration This feature is disabled by default. It can be enabled by a CLI toggle “logging transceiver” under the newly added “monitor layer1” config mode.

Arista 7280R Series Systems 10G, 25G, 50G Port Speed Configuration

Description This feature adds support for 10Gb, 25Gb, and 50Gb speeds on additional ports of the 7280QRA-C36S and 7280QR-C72: 7280QRA-C36S: Ports 13 through 23 can now be configured in 4x10G, 4x25G or 2x50G mode.  The paired even numbered ports (ports 14 through 24) are inactive when the first interface of the odd numbered port, physically above it, is configured for 10G or 25G. 7280QR-C72: Ports 11 through 25 and 47 through 61 can now be configured in 4x10G, 4x25G or 2x50G mode.  The paired even numbered ports (ports 12 through 26 and 48 through 62) are inactive when the first...

PTP ITU-T G8275.2

Description ITU-T G8275.2 is a PTP profile defined by ITU-T for telecommunication applications. It defines a set of functions from the IEEE 1588 to achieve phase/time synchronization with partial timing support from the network. Profile Definition  Terminology Synchronization service : Transmission of Announce, Sync and Delay_Resp (upon receiving Delay_Req) Grant port : Port that provides synchronization service. Request port : Port that is receiving synchronization service. E2E delay mechanism : Method of measuring path delay between two ports. Two ports exchange Delay_Req and Delay_Resp to measure the delay. Transparent Clocks will update the correction field and forward them instead of replying. P2P...
