Quotes About Switches

Analyzing Topology Using CDP and LLDP The first two major sections of this chapter showed two features—Syslog and NTP—that work the same way on both routers and switches. This final section shows yet another feature common to both routers and switches, with two similar protocols: the Cisco Discovery Protocol (CDP) and the Link Layer Discovery Protocol (LLDP). This section focuses on CDP, followed by LLDP.

Examining Information Learned by CDP CDP discovers basic information about neighboring routers and switches without needing to know the passwords for the neighboring devices. To discover information, routers and switches send CDP messages out each of their interfaces. The messages essentially announce information about the device that sent the CDP message. Devices that support CDP learn information about others by listening for the advertisements sent by other devices.

172.16.1.51 and vice versa. You can reasonably assume that the switches learned the MAC addresses of the router and the host, adding those to the MAC address tables. Host A and Router R1 completed the ARP process and list each other in their respective Address Resolution Protocol (ARP) tables. The failure of a ping, even with two devices on the same subnet, can point to a variety of problems, like those mentioned in this list.

I've seen a couple of singer switches happen right before my eyes, one being Roy Khan to Tommy Karevik in Kamelot, and the other was Anette Olzon to Floor Jansen in Nightwish.

A hero of the piece was John Draper, a hacker known as Captain Crunch because he had discovered that the sound emitted by the toy whistle that came with the breakfast cereal was the same 2600 Hertz tone used by the phone network's call-routing switches.

the human brain is a binary system—synapses either fire or they don't—they are on or off, like a computer switch. The brain has over a hundred trillion switches, which means that building a brain is not so much a question of technology as it is a question of scale.

And there in the next room by the sofa sat a familiar suitcase, that of his psychiatrist Dr. Smile. Barefoot, he padded into the living room, and seated himself by the suitcase; he opened it, clicked switches, and turned on Dr. Smile. Meters began to register and the mechanism hummed. Where am I? Barney asked it. And how far am I from New York? That was the main point...

a "story" hangs together, is treated whole. But once you tell your story into the law, it becomes the object of a precise semantic dissection.

Particular locutions trip particular legal switches, and set a heavy machine in motion.
