Description: The effective CAM size for this layer 2 traffic entry. Each unit is 8 bytes.
What is snCamUsageL2Size?
This value reports the total effective CAM capacity, in entries, allocated for layer 2 traffic (such as MAC address forwarding) on a given linecard's network processor. Administrators use it with snCamUsageL2Free to understand how much hardware table space is reserved for switching decisions on that card. For example, an snCamUsageL2Size of 16384 means that slot can hold up to 16,384 layer 2 forwarding entries.
