Cajun P550R/P880/P882 Installation Guide
Introduction
1-11
The media module’s features include:
■
IEEE 802.3x full-duplex flow control - This allows the switch
ports to send a pause command before input buffers overflow.
Half-duplex ports support active backpressure (jamming).
■
VLAN trunking or non-tagged access modes - This allows the
switch ports to interoperate with popular tagged trunking
schemes used by large networking vendors.
■
Priority Queuing and Class of Service - These features
allow you to prioritize traffic between particular stations or
sets of stations to support jitter-sensitive applications.
Supported class of service (CoS) types include the
following:
—
3COM PACE CoS
—
IEEE 802.1p CoS
—
Layer 3 tagging
Layer 2 and
Layer 3 Fast
