■ Speed—This will be either 1Gbit per second or 1 Gbit, 2 Gbit per second.
■ Block Port —Click this option to display a check mark and block port
transmission. If the port is blocked, a node attached to the port is prevented
from logging into the switch or communicating with other devices attached to
switch ports. A blocked port continuously transmits offline signals (OLSs).
Click to remove the check mark and unblock the port. If the port is unblocked,
a node attached to the port can communicate with the switch and can
communicate with other nodes attached to the switch.
■ Enable Beaconing—Click this option to make the amber LED by the port
blink on the actual switch and to make the amber indicator blink for the port
in the Hardware View. This enables users to locate the unit where the port is
located. When a blinking amber LED indicator displays by a port, an attention
indicator ( ) displays below the port's connector in the Hardware View and
on the port’s row in the Port List View.
■ Port(s) Diagnostics—Click this option to display the Port Diagnostics dialog
box. Use this dialog box to run an internal loopback and external loopback
test on the port. The Port(s) Diagnostics option enables you to run internal or
external loopback tests on any port. To use this option, follow the detailed
steps in the appropriate service manual for your Edge Switch.
■ Clear Link Incident Alert(s)—Click this option to clear the attention
indicator on the Hardware View, the Port List View, and the Performance
View. In addition, the procedure clears the alert description in Port Properties
dialog boxes. If there are no link incident alerts set for a port, no actions occur.
Although you can manually clear link incidents, they may also be cleared by
actions outside of the user interface, such as when the HAFM appliance is
rebooted.
■ Reset Port—Click this option to display a confirmation dialog box. Click Yes
to reset the port. If a switch is attached to the port and is online, this operation
sends a link reset to the attached switch; otherwise, this action disables port
beaconing for the port. If the port is in a failed state, such as after failing a
loopback test, the reset restores the port to an operational state, clearing the
service required (amber) LED. The reset does not affect other ports in the
switch.
