less than the configured port MTU, including the CRC at the end of the
frame.
For QinQ, the overall frame size is still calculated as described above,
◆
and does not add the length of the second tag to the frame.

These parameters are displayed:
Port – Port identifier. (Range: 1-28)
◆
Type – Indicates the port type. (Options: 1000BASE SFP,
◆
10GBASE XFP, 10GBASE SFP+)
Name – Allows you to label an interface. (Range: 1-64 characters)
◆
◆
Admin – Allows you to manually disable an interface. You can disable
an interface due to abnormal behavior (e.g., excessive collisions), and
then re-enable it after the problem has been resolved. You may also
disable an interface for security reasons. (Default: Enabled)
Media Type – Forces transceiver mode to use for SFP ports.
◆
None - Mode is not forced. (This is the default for SFP ports.)
■
SFP-Forced 100FX - Always uses 1000BASE-FX mode.
■
SFP-Forced 1000SFP - Always uses 1000BASE SFP mode.
■
SFP-Forced 10GSFP - Always uses 10GBASE SFP mode.
■
Autonegotiation (Port Capabilities) – Allows auto-negotiation to be
◆
enabled/disabled. When auto-negotiation is enabled, you need to
specify the capabilities to be advertised. When auto-negotiation is
disabled, you can force the settings for speed, mode, and flow
control.The following capabilities are supported.
1000f (Gigabit ports only) - Supports 1000 Mbps full-duplex
■
operation.
10Gf (10 Gigabit ports only) - Supports 10 Gbps full-duplex
■
operation.
Sym (Gigabit ports only) - Check this item to transmit and receive
■
pause frames.
FC (Gigabit ports only) - Flow control can eliminate frame loss by
■
"blocking" traffic from end stations or segments connected directly
to the switch when its buffers fill. When enabled, back pressure is
used for half-duplex operation and IEEE 802.3-2005 (formally
IEEE 802.3x) for full-duplex operation.
Default: Autonegotiation enabled;
