Port Configuration
– 115 –
For other traffic types, calculation of overall frame size is basically the same,
including the additional header fields SA(6) + DA(6) + Type(2) + VLAN-Tag(4) for
tagged packets, (for untaqged packets, the 4-byte field will not be added by
switch), and the payload. This should all be 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, but does
not add the length of the second tag to the frame.
Parameters
These parameters are displayed:
Port – Port identifier. (Range: 1-28)
Type – Indicates the port type. (1000BASE-T, 100BASE-FX SFP, 1000BASE SFP,
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 – Configures forced transceiver mode for SFP/SFP+ ports, or
forced/preferred port type for RJ-45/SFP combination ports
.
None - Forced transceiver mode is not used for SFP/SFP+ ports. (This is the
default setting for RJ-45 ports and SFP/SFP+ ports.)
Copper-Forced - Always uses the RJ-45 port.
(
Only applies to combination
RJ-45/SFP ports 21-24.)
SFP-Forced 1000SFP
- Always uses the SFP/SFP+ port at 1000 Mbps, Full
Duplex.
SFP-Forced
100FX - Always uses the SFP port at 100 Mbps, Full Duplex.
(
Only applies to SFP ports.)
SFP-Forced
10GSFP - Always uses the SFP+ port at 10 Gbps, Full Duplex.
Autonegotiation (Port Capabilities) – Allows auto-negotiation to be enabled/
disabled. When auto-negotiation is enabled
1
, you need to specify the
capabilities to be advertised. When auto-negotiation is disabled, you can force
the setting for speed, duplex mode, and flow control. The following capabilities
are supported.
10h - Supports 10 Mbps half-duplex operation.
10f - Supports 10 Mbps full-duplex operation.
