Parameter description:
Port :
This is the logical port number for this row.
Link :
The current link state is displayed graphically. Green indicates the link is up and
red that it is down.
Current Link Speed :
Provides the current link speed of the port.
Configured Link Speed :
Selects any available link speed for the given switch port. Only speeds supported
by the specific port is shown. Possible speeds are:
Disabled - Disables the switch port operation.
Auto - Port auto negotiating speed with the link partner and selects the highest
speed that is compatible with the link partner.
10Mbps HDX - Forces the cu port in 10Mbps half duplex mode.
10Mbps FDX - Forces the cu port in 10Mbps full duplex mode.
100Mbps HDX - Forces the cu port in 100Mbps half duplex mode.
100Mbps FDX - Forces the cu port in 100Mbps full duplex mode.
1Gbps FDX - Forces the port in 1Gbps full duplex
2.5Gbps FDX - Forces the Serdes port in 2.5Gbps full duplex mode.
SFP_Auto_AMS - Automatically determines the speed of the SFP. Note: There is
no standardized way to do SFP auto detect, so here it is done by reading the SFP
rom. Due to the missing standardized way of doing SFP auto detect some SFPs
might not be detectable. The port is set in AMS mode. Cu port is set in Auto mode.
100-FX - SFP port in 100-FX speed. Cu port disabled.
100-FX_AMS - Port in AMS mode. SFP port in 100-FX speed. Cu port in Auto
mode.
1000-X - SFP port in 1000-X speed. Cu port disabled.
1000-X_AMS - Port in AMS mode. SFP port in 1000-X speed. Cu port in Auto mode.
Ports in AMS mode with 1000-X speed has Cu port preferred. Ports in AMS mode
with 100-FX speed has fiber port preferred.
Flow Control :
When Auto Speed is selected on a port, this section indicates the flow control
capability that is advertised to the link partner. When a fixed-speed setting is
selected, that is what is used. The Current Rx column indicates whether pause
frames on the port are obeyed, and the Current Tx column indicates whether
pause frames on the port are transmitted. The Rx and Tx settings are determined
by the result of the last Auto-Negotiation.
Check the configured column to use flow control. This setting is related to the
setting for Configured Link Speed.
Maximum Frame Size :
Enter the maximum frame size allowed for the switch port, including FCS.
Excessive Collision Mode :
Configure port transmit collision behavior.
Discard:
Discard frame after 16 collisions (default).
Restart:
Restart backoff algorithm after 16 collisions.
