H3C S7500E Series Command Reference

3-22
Description
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 S7500E switch, make sure all the ONUs are enabled with
STP and no ONU acts as an STP root bridge to avoid network anomalies.
