Fastdrop static

Description Fastdrop static is a feature that allows the static multicast routing agent to respond to cache miss messages and dynamically create fastdrop routes. For 7280R/7500R based platforms, when multicast routing is enabled on an interface an mroute is needed to forward traffic to L3 and L2 OILs as the platform can only do S, G lookup or EthGroup lookup, not both. With dynamic multicast routing, this is taken care of by the PIM agent. The use case for this feature is when static multicast routing is being used, but there are not static mroutes for all S,Gs. If traffic...

Tap Aggregation support for hardware-accelerated sFlow

Description This feature enables support for hardware-accelerated sFlow while running in Tap Aggregation exclusive mode. This article will describe how to setup accelerated sFlow, for more information please view the hardware-accelerated sFlow article. Platform Compatibility Fixed platforms 7280SR2A-48YC6 7280CR2-60 7280CR2A-60 7280CR2K-60 7280CR2-30 7280CR2A-30 7280SRAM-48C6 7280SR2K-48C6 Modular platforms 7500R2A-36CQ-LC 7500R2AK-36CQ-LC 7500R2AM-36CQ-LC 7500R2AK-48YCQ-LC Configuration Follow the standard configuration for Tap Aggregation (using exclusive mode). To configure accelerated sFlow, configure the following: (config)# ip routing (config)# sflow run (config)# sflow hardware acceleration (config)# sflow destination (config)# sflow hardware acceleration sample 1024 To verify accelerated sFlow is functional, run the show command: (config)# show...

MPLS label swap and pop

Multiprotocol Label Switching (MPLS) is a networking process that replaces complete network addresses with short path labels for directing data packets to network nodes. The labels identify virtual links (paths) between distant nodes rather than endpoints. MPLS is scalable and protocol-independent. Data packets are assigned labels, which are used to determine packet forwarding destinations without examining the packet. Arista switches utilize MPLS to improve efficiency and control from servers through data centers and to the WAN. The MPLS implementation supports static MPLS tunneling that is manually configured on each switch or established over a network by an SDN controller. The...
