UNI Port Configuration
UNI Port Configuration Task List
If an H3C EC1001 inserted with a subcard serves as an ONU, a UNI port here refers to the internal
port connecting the subcard to the EC1001, but not the Ethernet port of the EC1001.
Complete these tasks to configure a UNI port:

UNI Port Basic Configuration
Duplex mode of a UNI: When a UNI works in full duplex mode, it can send and receive packets
simultaneously. When a UNI works in half duplex mode, it can either send or receive packets at a
time. When a UNI works in auto-negotiation mode, the duplex mode of the UNI is determined
through negotiation by both ends.
Flow control for UNIs: If the flow control function is enabled for both the UNIs and the remote
device, the ONU will send messages to notify the remote device to stop sending packets
temporarily when congestion occurs on the ONU, thus avoiding packet loss.
MDI mode for UNIs: The MDI mode for UNIs can be crossover or straight-through.
UNI port rate: You can set the UNI port rate. When the rate of a UNI is set to the auto-negotiation
mode, the operating rate of the UNI is negotiated by the local port and the remote port.
Auto-negotiation on a UNI: You can configure auto-negotiation on a UNI to enable both ends to
auto-negotiate the duplex mode, cable type, and port rate. After forced auto-negotiation is enabled,
the UNI port will restart the auto-negotiation.
