GRE tunnel configuration – DMF/BMF

DMF support L2-GRE tunneling, to transmit/receive encapsulated monitoring traffic over a network. This feature can be used to extend a DMF deployment across multiple data centers or branch offices over networks connected by Layer 3 networks. This supports centralization or distribution of tools and taps/spans across multiple locations when they cannot be directly connected.   Scenario 1: Using GRE tunnel as a core interface. For core links, the direction of the tunnel should be bidirectional and encap loopback interface is required. Both endpoints will periodically transmit LLDP frames, and DMF will discover that the tunnel is a core link. The...

These upgrade steps are also present in the DMF deployment guide, starting on chapter 6. https://www.arista.com/en/support/software-download Switch/Node upgrades After the controllers have upgraded, the switches will automatically reboot to upgrade. Service nodes, starting from 7.x.x, will upgrade automatically similarly to fabric switches. Analytics and Recorder nodes need to be upgraded separately, which will be covered later in this document.   Steps for Upgrading Controllers 7.x.x to 8.x.x 1. Download your intended upgrade version ISO from the software downloads...

DMF Downgrade/ Fresh Install

DMF Downgrade/ Fresh Install   Please be advised downgrading of DMF version image using the “upgrade launch” procedure is not supported. There are 2 ways to perform the downgrades. Loading the alternate boot partition which consists of the previous DMF version image or doing a fresh install via IDRAC. IDRAC Fresh install may be used when you don’t have the previous DMF image on the alternate partition. IDRAC Fresh Install Using IDRAC we can perform a fresh install of the ISO on a device. The process is the same for Controller nodes, Analytics nodes, and Service nodes. Ensure you have...
