Note
Switch ports that are connected to 10 or 100 Mbps end nodes that

set their speed and duplex mode settings, because duplex mode
mismatches might occur. You should disable Auto-Negotiation and
set the speed and duplex mode settings manually with the
AlliedWare Plus Operating System.

The ports on the AT-SBx81GT40 Line Card and AT-SBx81XLEM/
