Modify speed and duplex settings for hardware appliances

By default, the network interfaces are configured for auto-negotiation. Use the command line to change the speed and duplex settings.

Using a command-line session, log on to the appliance.
From the options menu, select the Shell option.
View the help on forming the command.
$ /opt/NETAwss/mgmt/nic_options -?
- Use lan1 for the client interface and mgmt for the management interface.
- --(no)autoneg turns auto-negotiation on or off. The default is on.
- --duplex specifies the duplex — half or full. The default is full.
- --speed specifies the network speed in Mb/s 10000 (Trellix DLP 8800, Trellix DLP 7700, and Trellix DLP 6600), 1000, 100, or 10.
  The default is 10000 Mb/s for Trellix DLP 8800, Trellix DLP 7700, and Trellix DLP 6600 appliance models.
- --mtu specifies the Maximum Transmission Unit (MTU) size in bytes — a value between 576–1500. The default is 1500.
Enter the command to change the setting. Examples:
- To disable auto-negotiation and set a network speed of 100 Mb/s on the client interface:
  $ sudo /opt/NETAwss/mgmt/nic_options --noautoneg --speed 100 lan1
- To restore the default behavior to the management port:
  $ sudo /opt/NETAwss/mgmt/nic_options mgmt
