This MIB contains information about the capacity and utilization of hardware resources on Arista devices. Arista ships and supports devices which perform packet forwarding decisions in hardware. To make these forwarding decisions (L2 bridging, input and output access list, L3 forwarding based on IP destination etc.), the devices use information programmed in various hardware resources. Examples of such hardware resources are the hash table used for MAC address lookup, TCAM for destination IP lookup etc. Each of Arista's devices have different hardware resource capacity or size limits. It is extremely useful for a Network Management system to be able to query and monitor the utilization of these hardware resources. Due to unxpected network event or configuration change, it is possible that a specific hardware resource is over utilized and there is no room to program additional entries. For example, a routing mis-configuration can result in overflowing the L3 forwarding TCAM. This may be detrimental to the network operation. So it's extremely useful to monitor the utilization of the various hardware resources of a specific device. On some devices, due to hardware design considerations, several features may have to share a single hardware resource. If one feature ends up using more of the same resource, it can affect the functionality of another feature. This is another reason to have visibility into the hardware resource usage. The hardware element that makes the forwarding decision is frequently referred to as the 'Forwarding ASIC' or 'Forwarding Chip'. In this MIB document we refer to this hardware element as 'Forwarding Element'. Even though a device can have multiple forwarding elements, the information programmed in each of the forwarding element is typically the same. But there are some cases, where this is not the case. In such instances, the utilization of relevant hardware resource(s) may not be the same across all the forwarding elements. This MIB module provides the hardware capacity and utilization information for various resources in a generic manner, that's applicable to all Arista devices.
