Changing port speeds
The 1-Gbps/2-Gbps/4-Gbps ports are capable of transmitting and receiving at 1-Gbps, 2-Gbps, or
4-Gbps. The ports can be configured for either transmission speed or to sense the transmission speed of
the device to which it is connected. Table 25 describes the port speeds. To change the port speed, perform
the following procedure:
1. Select one or more 1-Gbps/2-Gbps/4-Gbps ports in the faceplate display.
2. Select Port > Port Properties.
3. Select the option that corresponds to the port speed you want.
4. Click OK to write the new port speed to the switch.
Changing port types
The ports can be configured to self-discover the proper type to match the device or switch to which it is
connected. Table 26 describes the port types. To change the port type, perform the following procedure:
1. Select one or more ports in the faceplate display.
2. Select Port > Port Properties.
3. Select the option for the port type you want.
4. Click OK to write the new port type to the switch.
Device scan
The Device Scan feature queries the connected device during login for FC-4 descriptor information.
Disable this parameter only if the scan creates a conflict with the connected device.
Table 25 Port speeds
State Description
Auto-Detect Matches the transmission speed of the connected device. This is the
default.
1Gbps Sets the transmission speed to 1-Gbps
2Gbps Sets the transmission speed to 2-Gbps
4Gbps Sets the transmission speed to 4-Gbps
Table 26 Port types
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
32 public devices (NL_Port). The default internal port type.
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 external 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.
