port that does support auto-negotiation. If two gigabit
ports that support auto-negotiation are connected, you
should enable auto-negotiation.
—
Auto-negotiation and remote fault detection cannot be
enabled concurrently. Auto-negotiation must be disabled
in order to enable remote fault detection. When auto-
negotiation is enabled, remote fault detection is
automatically disabled.
—
For gigabit modules, auto-negotiation is always disabled.

Parameter Definition
Name A user-assigned name for this port (possibly a drop
name or the name of the station or other device
connected to the port).
Category Enables you to select either User Port or Service
Port. The
User Port is intended for use with
switch connections to end user nodes. The
Service Port is intended for use with switch
connections to servers or other switches.
The primary difference between the User and
Service Port designation is that a Service Port
allows the switch to generate both log messages and
alarm messages (traps). The User Port only
generates log messages. This prevents your
network management station from being
overwhelmed by port up/down messages that
result from users turning workstations on and off.
Flow
Control
Mode Determines if IEEE 802.3z pause control is used
on this port. The pause mechanism allows the port
to stop a sending station from sending more
packets if the receiving port’s buffers are full. This
helps prevent lost or dropped packets.
This feature is recommended for use primarily on
end station connections. Using this feature on
trunk ports can cause unnecessary congestion on
the network.
