Vxlan Trident L2-Uplink Limitation 113722

If you’ve tried implementing VXLAN on Trident VTEPs with a Layer-2 uplink to remote-vteps, you may have noticed that sometimes packets can’t be successfully forwarded across the VXLAN fabric, or perhaps the latency observed is higher than what’s expected. Alternatively, maybe you never noticed the above symptoms and are here instead because you noticed the following log in your switch: STRATA-6-VXLAN_PORT_TO_NEXTHOP_OVERFLOW. These are the most common observations made when a Trident switch has hit the following limitation, 113722, found in EOS Release Notes: Limitations and Restrictions in 4.26.1F 7300X3, 7320X, 7368, CCS-720XP, CCS-750, DCS-7010, DCS-7050X, DCS-7050X2, DCS-7050X3, DCS-7060X, DCS-7060X2, DCS-7060X4,...

Default Control Plane ACL Explained

Explaining the default Control Plane ACL- Control-plane traffic is defined as the traffic that is destined to or sourced from the CPU. An access-list applied to the control-plane traffic is called the control-plane ACL. By default, every Arista switch comes configured with a control-plane ACL, named ‘default-control-plane-acl’, which cannot be modified (read-only). To add to the control-plane ACL, you should create a new ACL and apply it to the control-plane (see next section). When customizing the default CP-ACL, be wary of removing original rules which could negatively impact necessary traffic on your network. Please see the Caveats section as examples....
