Autonegotiation must be disabled before you can configure or force the interface to
use the Speed/Duplex Mode or Flow Control options.
Web – Click Port, Port Configuration or Trunk Configuration. Modify the required interface
settings, and click Apply.

NXA-ENET Software Management Guide
Sym (Gigabit only) - When specified, the port transmits and receives pause frames;
when not specified, the port will auto-negotiate to determine the sender and receiver
for asymmetric pause frames. (The current switch chip only supports symmetric
pause frames.)
FC - Supports flow control
Flow control can eliminate frame loss by "blocking" traffic from end stations or
segments connected directly to the switch when its buffers fill. When enabled, back
pressure is used for half-duplex operation and IEEE 802.3x for full-duplex operation.
(Avoid using flow control on a port connected to a hub unless it is actually required to
solve a problem. Otherwise back pressure jamming signals may degrade overall
performance for the segment attached to the hub.)
(Default: Autonegotiation enabled; Advertised capabilities for 100BASE-TX – 10half,
10full, 100half, 100full; 1000BASE-T – 10half, 10full, 100half, 100full, 1000full;
1000BASE-LX – 1000full)
Trunk – Indicates if a port is a member of a trunk. To create trunks and select port
members, see Creating Trunk Groups section on page 96.
