In November 1781, John Hanson became the first President of the United States in Congress Assembled, under the Articles of Confederation. Many people have argued that John Hanson, and not George Washington, was the first President of the United States, but this is not quite true.
Even and odd mode impedances of a coupled microstrip line. actually I find the reason when you use differential port, the impedance you get is twice the odd mode impedance, whereas if you use common port, the impedance is half the even mode impedance. 1 members found this post helpful.
In this case, where the 1/1 port of switch B is configured for auto-negotiation and the 1/1 port of switch A is not, the 1/1 port of switch B is forced to select the default duplex mode. On Catalyst Ethernet ports, the default mode is auto-negotiate. If auto-negotiation fails, the default mode is half-duplex.hange the speed on port 1/1 in switch A to 10 Mb. In order to demonstrate what occurs when one link partner auto-negotiates and the other link partner does not, the speed on port 1/1 in switch A must be set to 10 Mb. Issue the set port speed 1/1 10 command to set this speed.
