Port Types
To display port type status, open the View menu, and select
View Port Types
.
Table 5-6
lists the possible port types and their meanings. The ports can be
configured to self-discover the proper type to match the device or switch to which
it is connected. The Running Type field on the Port Properties dialog indicates the
port type that is currently active.
To change the port type, do the following:
1.
Select one or more ports in the faceplate display.
2.
Open the Port menu and select
Port Properties
to open the Port Properties
dialog.
3.
Select the
Port Type
option from the drop-down list.
4.
Click the
OK
button to write the new port type to the switch.

Port Speeds
SFP ports are capable of transmitting and receiving at 1-Gbps, 2-Gbps or 4-Gbps.
XPAK ports are capable of transmitting and receiving at 10-Gbps. All ports can be
configured for either a fixed transmission speed or to sense (auto-detect) the
transmission speed of the device to which it is connected. To display the speed of
each port, open the View menu and select
View Port Speeds
.
Table 5-7
lists the
possible port speeds.
To change the port transmission speed, do the following:

State
Description
F_Port
Fabric port — supports a single public device (N_Port).
FL_Port
Fabric loop port — self discovers a single device (N_Port) or a loop of up
to 126 public devices (NL_Port). 1/2/4-Gbps ports only.
G_Port
Generic port — self discovers as an F_Port or an E_Port.
GL_Port
Generic loop port — self discovers as an F_Port, FL_Port, or an E_Port.
GL_Port is the default port type. A single device on a public loop will
attempt to configure as an F_Port first, then if that fails, as an FL_Port.
1/2/4-Gbps ports only.
E_Port
Expansion port — the mode that a G_Port or GL_Port is in when attached
by an ISL (inter-switch link) to another fibre channel switch.
Donor
Donor port — allows buffer credits to be used by another port.
