2: System level 

stp: Enables RSTP for the ONU.  

dhcp-snooping: Enables DHCP-Snooping for the ONU.  

dhcp-snooping information: Enables DHCP-Snooping Option82 for the ONU.  

pppoe: Enables PPPoE+ for the ONU.  

Use the onu-protocol enable command to enable RSTP, DHCP-Snooping, DHCP-Snooping Option82, 

or PPPoE+ for the ONU.  

Use the undo onu-protocol enable command to disable the specified feature(s). 

By default, RSTP is enabled for the ONU, while DHCP-Snooping, DHCP-Snooping Option82, and 

PPPoE+ are disabled for the ONU.  

 

 

This command takes effect on H3C ONUs only.  

 

STP runs normally only when all attached ONUs are H3C ONUs.  

 

When STP is enabled globally on the S7900E switch, make sure all the ONUs are enabled with 

STP and no ONU acts as an STP root bridge to avoid network anomalies.  

 

# Enable DHCP snooping on the ONU.
