You can use the network port modify command to modify the port type (cluster, data, or management), MTU, autonegotiation, administrative duplex, and administrative speed settings for a network port.
The following guidelines and limitations apply to modifying a network port:
Port-naming conventions are described in “Network Port Naming Conventions”.
The values that you can set for duplex mode and port speed are referred to as administrative settings. Depending on network limitations, the administrative settings can differ from the operational settings (that is, the duplex mode and speed that the port actually uses).
The following example sets the autonegotiation setting to false for port e0b on node node1b:
node::>network port modify -node node1b -port e0b -autonegotiate false
