d. Click a check box in the 10-100 km column to define extended distance
buffering. (This column is not available on the Edge Switch 2/24.) A
check mark in the box indicates extended distance buffering is enabled.
You can enable extended distance for a port even if it is not an extended
distance port. However, enabling extended distance buffering for a port
disables the ability of the port to send broadcast traffic. When you choose
this option, the port can support up to 60 buffer-to-buffer credits
(BB_Credits) to handle link distances up to 100 km. This enables the port
to process 2K frames from attached devices. If this option is not enabled,
the port uses the BB_Credit value.
Note: If a device is connected and logged in to the fabric when extended distance is
enabled or disabled on the corresponding port, the HP product sends OLS for
5 milliseconds to force the device to log in again and obtain the new BB_Credit value
set for the port.
e. Choose from the drop-down list in the Type column to configure the port
type. Available selections are:
— G_Port — Generic port.
— F_Port — Fabric port.
— E_Port — Expansion port.
— GX_Port — Generic mixed port. Use this selection to configure a
port as a generic loop port (GL_Port). The port automatically
negotiates any connection type (Edge Switch 2/24 only).
— FX_Port — Fabric mixed port. Use this selection to configure a port
as a fabric loop port (FL_Port). The port automatically negotiates
F_Port and FL_Port connections only (Edge Switch 2/24 only).
f. Choose from the drop-down list in the Speed column to configure the port
transmission rate. Available selections are:
— Negotiate — Auto-negotiate between 1.0625 and 2.125 gigabits per
second (Gbps) operation. This is valid only on products that are
capable of 2 Gbs operation.
— 1 Gb/sec — 1.0625 Gbps operation.
— 2 Gb/sec — 2.125 Gbps operation.
