The port becomes a trunk port even if the neighboring port does not agree to the change. Dynamic Auto — Makes the Ethernet port willing to convert the link to a trunk link. The port becomes a trunk port if the neighboring port is set to trunk or dynamic desirable mode. This is the default mode for some switchports.
Frequent use of a serial port is for a direct computer-to-computer connection. This requires an adapter called a null modem, which isn't actually a modem in the traditional sense, but rather a connector plug that simply crosses the complementary pins on two serial ports so the two sides can communicate. A null modem typically connects the DTR ...

The first chassis in the Nexus 7000 family is a 10-slot chassis with two supervisor engine slots and eight I/O module slots at the front, as well as five crossbar ...
Settings for hardware RAID or RAM timings can also be adjusted as the management card needs no hard drives or main memory to operate. [1] As management via serial port has traditionally been important on servers, a complete remote management system also allows interfacing with the server through a serial over LAN cable.
A Link Control Protocol (LCP) to establish, configure, and test the link as well as negotiate settings, options and the use of features. One or more Network Control Protocols (NCP) used to negotiate optional configuration parameters and facilities for the network layer. There is one NCP for each higher-layer protocol supported by PPP.
