chportethernet
Use the chportethernet command to configure the permitted uses of ethernet ports and the maximum transmission unit (MTU) setting for the ethernet.
Syntax
Parameters
- (Optional) Specifies the I/O group that contains the nodes to modify.
- (Optional) Specifies port that is used for host attach (the existing system settings are
retained). Specifying:
- yes turns on IP host attached functionality for that port (default).
- no turns off IP host attached functionality for that port.
- (Optional) Specifies whether the port can be used for backend storage functionality. The values
are yes and no.
- The value yes indicates that this port can be used for backend storage connectivity (default).
- You must specify no if you are not using backend storage.
- (Optional) Specifies whether the port can be used for remote copy. The values are yes and no.
- (Optional) Specifies the maximum transmission unit (MTU). The default is 1500, with a maximum of
9000. Specify -defaultmtu to use the default
value.Note:
- This parameter must be used when you are setting or changing the port MTU value.
- The port MTU value for the 100 Gbps adapter must be set at 1500. The default port MTU value for 100 Gbps is 1500, and any value other than the default value is not supported.
- (Required) Specifies the port on which changes are applicable. Value can be in between 1 - 16.
