High-Density Ethernet Overview

The following modules support high-density Ethernet:

In the current release, you cannot configure port parameters for high-density Ethernet. Instead, JunosE Software contains a packet classifier that enables the module to intelligently drop certain packets when the module becomes oversubscribed. The packet classifier inspects each incoming packet to determine whether to classify it as control traffic. To enhance network stability, the packet classifier prioritizes control traffic over non-control traffic (that is, data). The packet classifier randomly drops non-control packets when the interface is oversubscribed.

When the I/O module or IOA is oversubscribed, the packet classifier prioritizes the following types of control traffic:
