Enable – Send Only

Enable – Respond Only

The Disable option disables flow control (the default).

The Enable option enables IEEE802.3X (XOFF/XON) Flow Control

on the line. The Avaya Multiservice Switch is the sender of pauses

based upon inbound traffic and the Avaya Multiservice Switch is the

receiver of pauses based upon outgoing traffic (and the ability of

attached equipment to use the protocol).

With Gigabit links, you can:

Enable IEEE802.3X for both send and receive (the "Enable"

Only send pause (XOFF/XON) signals (the "Enable – Send Only"

Only respond to the pause signals (the "Enable – Respond

Only" option).

With 10/100 links you can use the Enable with Aggressive

Backoff option to enable Active Backpressure (creation of a

collision) on a link. Active Backpressure only applies to HD links so

that when a 10/100 link is in FD, options 2 and 3 are identical.

Refer to Table 5-1 lists the gigabit modules that do not support auto
