How to recover flood-list and mac address learning when using OVSDB management

Hi, I am a beginner of Arista switch. I have two questions on that. <Information of the switch>model:Arista DCS-7150S-64-CLversion:EOS-4.15.7M 1) The flood-list and the mac address  learning disappears when the switch restarts. Why? I set the infomation that “HER flood-list and mac address learning” on the Arista switch that using the OVSDB management. Example of setting  is as follows.(The following command executed on CVX.)-bash-4.1# vtep-ctl add-mcast-remote <LS-name> unknown-dst vxlan_over_ipv4 <vtep-ip>-bash-4.1# vtep-ctl add-ucast-remote  <LS-name>  <MAC-address> vxlan_over_ipv4 <vtep-ip> One day, I stopped the Arista switch and started it.Then, the information(HER flood-list and mac address  learning) disappeared from Arista switch…Note: I confirmed it by...

Bug Alerts

Bug-Alerts is a service that runs on Arista CloudVisionTM eXchange (CVX) that provides customers with information on known, resolved bugs that are impacting Arista switches. The feature collects switch properties such as EOS version, hardware platform, configuration and operating conditions of all connected switches. It uses these switch properties and a local database of known bugs to determine the list of impacting bugs for each switch. This information is then displayed via show commands on CVX. The complete Bug-Alerts feature consists of the following components: CVX components AlertBase – This is the database of known and resolved bugs in Arista...

VXLAN Without Controller for Network Virtualization with Arista physical VTEPs

  1) Introduction This article assumed an understanding of the VXLAN concepts. This article aims at guiding the design and implementation of network virtualization with VXLAN, employing physical VTEPs. This controller-less design provides Layer2 communication across a Layer3 network for any Layer2 Ethernet device. This solution guide resolves network virtualization for network teams that might not have yet a network virtualisation controller, or cloud management platform (CMP), but want to benefit now from all the advantages of VXLAN. Without network controller, the virtual switches will not participate natively in the VXLAN overlay setup, they would be configured the traditional way...

Configure CVX and VXLAN with Ansible

Purpose: This Ansible playbook allows an administrator to easily configure a Cloud Vision Exchange (CVX) environment as well as configure a Virtual Extensible LAN (VXLAN) between two switches in an environment built using Arista switches, whether they be physical or virtual (vEOS). It is ideally suited for test environments and administrators wanting to test CVX and VXLAN. The playbook can be modified for more complex deployments. Running the playbook: From the /etc/ansible directory in the Linux CLI run: ansible-playbook cvx_vxlan_playbook.yaml Prerequisites: An Ansible server (http://docs.ansible.com/ansible/intro_installation.html) arista.eos roles for Ansible v1.0.1 # sudo ansible-galaxy install arista.eos. Rename the following files under...

Ansible playbook for CVX and VXLAN configuration.

Purpose: This playbook allows an administrator to easily configure Cloud Vision Exchange (CVX)  and Virtual Extensible LAN (VXLAN) between two Arista switches. It is ideally suited for test environments and administrators wanting to test CVX and VXLAN functionality. The playbook can be modified for more advanced deployments. Running the playbook: From the cli under the /etc/ansible directory run: ansible-playbook cvx_vxlan_playbook.yaml Prerequisites: An Ansible server (http://docs.ansible.com/ansible/intro_installation.html) arista.eos roles for Ansible v1.0.1. To install run # sudo ansible-galaxy install arista.eos on the Ansible server. Rename the following files under /etc/ansible/roles/arista.eos/library to not have a .py extension i.e eos_config.py becomes eos_config.  # cp...
