In addition to the ISDN interfaces, we have an Ethernet interface that connects up to a unit in your LAN, frequently a hub or perhaps a computer. If linking up to a Hub uplink port, you then set the tiny switch to "Hub", however if linking to a Computer, you`ll want to set it to "Node". This switch will just transform the cable from a straight through (hub) to a x- over (Node):
The Config or Console port is really a feminine DB9 connector that you simply link, utilizing a special cable, to your computer systems serial slot plus it allows you to directly configure the router.The Processor (CPU) All Cisco routers have a primary processor that protects the primary functions for the router. The Central Processing Unit generates interrupts (IRQ) so that you can talk to the other components that are electronic the router. The routers utilize Motorola RISC processors. Usually the CPU utilisation on a normal router wouldn`t meet or exceed 20 %.
The IOS
The IOS could be the main os on that the router runs. The IOS is loaded upon the router`s bootup. It usually is about 2 to 5MB in size, but could be a complete lot bigger with respect to the router show. The IOS is currently on version 12, and they sporadically releases small versions every couple of weeks e.g 12.1 , 12.3 etc. to repair little pests and also include functionality that is extra.
The IOS provides the router its capabilities that are various can also be updated or downloaded from the router for backup purposes. In the 1600 series and above, the IOS is got by you for a PCMCIA Flash card. This Flash card then plugs as a slot found at the straight back regarding the router and also the router loads the IOS "image" (as they call it). Usually this image of the os is compressed and so the router must decompress the image in its memory so that you can utilize it.
The IOS is one of the most significant elements of the router, without one the router is pretty much useless. Just take into account that it is not required to have flash card (as described above utilizing the 1600 series router) so that you can load the IOS. It is possible to configure many routers to load the image off a community tftp server or from another router which might hold multiple IOS images for various routers, in which case it`ll have a capacity that is large card to store these images.
