Disabled - Disables the switch port operation.
10Mbps HDX - Forces the port in 10Mbps half duplex mode.
10Mbps FDX - Forces the port in 10Mbps full duplex mode.
100Mbps HDX - Forces the port in 100Mbps half duplex mode.
100Mbps FDX - Forces the port in 100Mbps full duplex mode.
1Gbps FDX - Forces the port in 1Gbps full duplex
2.5Gbps FDX - Forces the port in 2.5Gbps full duplex mode.
5Gbps FDX - Forces the port in 5Gbps full duplex mode.
10Gbps FDX - Forces the port in 10Gbps full duplex mode.
Auto - Port auto negotiating speed and duplex with the link partner and selects the highest speed that is
compatible with the link partner.
Cable Type: This selection is for 10G ports only (e.g., Ports 29-32):
Auto: SFP interface in "auto" mode. Automatic SerDes tuning for optical and DAC-3m
cables.
DAC-1m: SFP interface in "DAC-1m" mode. Manual SerDes tuning specifically for DAC-1m
cables.
DAC-2m: SFP interface in "DAC-2m" mode. Manual SerDes tuning specifically for DAC-2m
cables.
DAC-3m: SFP interface in "DAC-3m" mode. Manual SerDes tuning specifically for DAC-3m
cables.
DAC-5m: SFP interface in "DAC-5m" mode. Manual SerDes tuning specifically for DAC-5m
cables.
Advertise Duplex: When duplex is set as Auto (auto negotiation) the port will only advertise the specified duplex
as either Fdx (full duplex) or Hdx (half duplex) to the link partner. By default, port will advertise all the supported
duplexes if the Duplex is Auto.
Advertise Speed: When Speed is set as Auto (auto negotiation) the port will only
advertise the specified speeds (10M, 100M, 1G, 2.5G, 5G, or 10G) to the link partner.
By default port will advertise all the supported speeds if speed is set as Auto.
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. Note: The 100FX standard doesn't support Auto Negotiation, so when in 100FX mode
the flow control capabilities will always be shown as "disabled". PFC and Flow control cannot both be enabled on
the same port.
PFC: When PFC (802.1Qbb Priority Flow Control) is enabled on a port then flow control on a priority level is
enabled. Through the Priority field, range (one or more) of priorities can be configured, e.g., '0-3,7' which equals
'0,1,2,3,7'. PFC is not supported through auto negotiation. PFC and Flow control cannot both be enabled on the
same port.
Maximum Frame Size: Enter the maximum frame size allowed for the switch port, including FCS. The range is
1518-10240 bytes.
Excessive Collision Mode: Configure port transmit collision behavior. Can be either:
Discard: Discard frame after 16 collisions (default).
Restart: Restart backoff algorithm after 16 collisions.
