Hello, everybody!


This post enquires about the S6700 auto-negotiation. Please check more details below.

Huawei S6700

ISSUE DESCRIPTION


I have just received my first 2 Huawei switches - S6700.


Unfortunately, I am having problems connecting clients to the switches, as it appears the switches do not support auto-negotiation.


I am running version V100R006C00SPC800, with patch V100R006SPH017.


When trying to enable auto-negotiation on a port, I get the following error:


Error: This port or this mode doesn't support this command.


Any idea how I can enable S6700 auto-negotiation? Thanks.

Hi Paul,

 

Auto negotiation is fully supported and is switched on by default.

You can disable it using the "undo negotiation auto" command on the interface.

You can then manually specify a speed and duplex setting using the "speed xxx" and the "duplex xxx" commands.

The ports support auto negotiation of speed, duplex and mdi/mdix by default and I have never seen any negotiation issues on these switches!

You also have the "virtual-cable-test" command to test for cable problems on the link, although this is service affecting.

Have you tried connecting the switches to each other or from port to port on a switch to prove the cables and the ports come up?

 

Regards Nigel
