Monitoring and managing the switch 58
• Distance—General distance range for port transmission. This can be either short to long
distances for longwave laser LC transceivers or short distances for shortwave laser LC
transceivers.
• Media—The Fibre Channel mode and optic size. For the longwave laser LC transceiver, this
would be singlemode 9-micron. For the shortwave laser LC transceiver, this would be multimode
50-micron or 62.5-micron.
• Speed—This will be either 1Gbit per second or 1Gbit per second, 2 Gbit per second. Note
that only 1 Gbit per second ports operate in the 1 Gbit switches.
• 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.
• Channel Wrap (FICON management style only)—Click this while in FICON
management style to display a check mark and allow a channel wrap test to be initiated from
an attached host or device. In this test, frames are sent to the switch port, then the switch echoes
the frames back to the sending device to test the channel. The switch remains in channel wrap
mode until the option is disabled. While in channel wrap mode, the port can only accept echo
commands from the host and will appear to be blocked to all other communication. Click the
check box to remove the check mark and disable channel wrap.
• 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.
