Problem
This document discusses frames found on the network with an Ethernet frame type of 886D.
Resolving The Problem
A communications trace formatted for broadcast data often has a high number of packets with a type of 886D. These packets are Intel proprietary heartbeat packets. They are unknown; therefore, the adapter tries to identify them. There is much more processing required for the unknown packet than there is for a known packet type. If the card processes a large number of these unknown packets, it can cause performance issues. Below is an excerpt from an Intel Web site that explains what these packets are used for.
| Probe Packets and Settings Note: The following text was extracted from the above-mentioned article. However, the bold text was highlighted to assist users. "AFT and ALB teams use probe packets. Probes are packets (type 886D, either multicast or broadcast) passed over the network between team members to allow the ANS software to test the member's status. They do add a minor amount of traffic to the network and should be turned off in near capacity networks. " |
