NE80E version: VRP5.30-31002S.03
Symptoms: The mode of sub-interface of ETH_24XGE_CARD is changed, and it influences the mode of interface.
1. Set the mode of interface of ETH_24XGE_CARD to 100M full duplex. Use display this command to check the configuration information of duplex; use display interface (such as G10/0/0) command, and we can know that the interface works at 100M full duplex; use display interface sub-interface (such as G10/0/0.100) command, and we can know that the interface still works at 100M full duplex. Enter the sub-interface, and execute display this command, but we cannot find the configuration of 100M full duplex, but the sub-interface has the options as speed 10, 100, auto and duplex 10, 100 and auto. Changing the mode of sub-interface makes that of interface change also.
2. In NE80E, the sub-interface of ETH_10XGE_CARD does not have speed, duplex and negotiation auto, undo negotiation auto commands.
3. In other routes as AR46, the sub-interface does not have the similar commands like speed, duplex and negotiation auto, undo negotiation auto.
The mode should be set in interface, and the sub-interface should remove the setting for working mode, avoiding that mis-operation can influence the state of interface. For the setting of interface of NE80E, pay attention to the influence of sub-interface configuration on interface.
