sometimes when interface configured with a static IP address, which is not correct, the host does not communicate to the port, and switch has no MAC address. I've seen it just two days ago - had an Linux appliance with a static IP address configured on the interface. Plugged interface to the switch, port says "Connected", but no MAC address in the CAM table. After I changed an IP address to whatever it should be for the VLAN - NIC started to communicate, and MAC address appears on the port.
First you have to configure your NIC card, preferably with a static IP address. Then, tell the webserver software which port and which address to listen on.
NAS IP is the IP address of a switch or another type of a radius client. NAS Port is a little harder to explain, but it is a number that is assigned to the interface authenticating and edge device. Similar to the NAS PORT ID, but not static.
COM port is used to configure a router but you can also get a COM port to USB port adapter which can configure a router using a USB port.
router> enablerouter# configure terminalrouter(config) interface serial (interface number)router(config-if) no shutdownrouter(config-if) endrouter#substitute (interface number) for the actual int number.. eg serial 0/1you can find the number of the interface by using show interfaces from privileged mode
Only if my router didn't support any other interface.
PAT - Port Address Translation only needs a single IP address for 65,000 connections.
You seem to be referring to a NIC (Network interface card).

Yes. Routers normally have more than one IP address.
Yes, By default port security is disabled on a Cisco switch. If it is enabled the default violation mode is shutdown with a maximum MAC address count of 1. Even if port-security is enabled it will not place a port into the shutdown state until either MAC address sticky or a static MAC address is configured on the port.
The IEEE 1394 Interface or Port is also know by it's Apple Mac name as FireWire.
