Description
Ethernet Interface 1
Description
Provides a free-form description for the Ethernet interface.
Auto Negotiation
If
Auto Negotiation
is enabled, the appliance communicates with the network to automatically determine the fastest common communication speed and duplex mode.
Speed
If
Auto Negotiation
is disabled, specify the appliance network speed.
Duplex
If
Auto Negotiation
is disabled, specify the appliance duplex mode. Ensure that the specified duplex mode matches your network.
Enable TCP Segmentation Offload
If
Enable TCP Segmentation Offload
is checked, the NIC handles TCP segmentation instead of the CPU. This option can improve throughput for high-volume, high-bandwidth networks.
Maximum transmission unit
Works in tandem with the TCP segmentation offload.
You can enter a value from 512 bytes to 1500 bytes.
When TSO is enabled and the default maximum transmission unit is blank, the value is whatever the NIC (network interface card) specifies for its maximum value. Typically, this value is 1500 bytes maximum for an Ethernet link.
When you change this value, you must then restart the Control Center using the
service controlcenter restart
command.
