Subnetting an IP Network is done primarily for better utilization of available IP address space, and routing purpose. Other reasons include better organization, use of different physical media (such as Ethernet, WAN, etc.),  and securing network resources. A subnet mask enables you to identify the network and node parts of the address. The network bits are represented by the 1s in the mask, and the node bits are represented by the 0s. A logical AND operation between the IP address and the subnet mask provides the Network Address. For example, using our test IP address and the default Class C subnet mask, we get: 192.189.210.078: 1100 0000.1011 1101.1101 0010.0100 1110 Class C IP Address 255.255.255.000: 1111 1111.1111 1111.1111 1111.0000 0000 Default Class C subnet mask  192.189.210.0         1100 0000 1011 1101 1101 0010 0000 0000 As can be seen above, by using and AND operator, we can compute the network portio...

An IP address is a unique logical identifier for a node or host connection on an IP network. An IP address is a 32 bit binary number, and represented as 4 decimal values of 8 bits each. The decimal values range from 0 to 255. This is known as "dotted decimal" notation. Example: 192.189.210.078 It is sometimes useful to view the values in their binary form. 192     .189     .210     .078 11000000.10111101.11010010.1001110 Every IP address consists of network identifier and node identifier. The IP network is divided based on Class of network. The class of network is determined by the leading bits of the IP address as shown below. Address Classes There are 5 different address classes. You can determine which class any IP address is in by examining the first 4 bits of the IP address. Class A addresses begin with 0xxx , or 1 to 126 decimal. Class B address...

Hi all. Here i am with yet another tutorial. Programming in IOS. Dont confuse it with programming IOS because you cant do it. IOS is not open source so you cant make extensions/modifications to it, But IOS allows you to use TCL ( pronounced "tickle" ) scripting language to write scripts to get tasks done in a different and more feasible way, that was either not possible before or too complicated. One example is the recent query posted by our fellow member superr about how to monitor snmp OID to trigger events. Although the solution was in EEM, but the same could be done using tcl. Those who are totally new to this stuff will be getting confused as to what i am talking about. So lets see a few examples, that are very practical and you may encounter tasks similar to these more often. Example 1) When router cpu utilization reaches 30%, send an email to me, plus give only the first five top processes in "sh process cpu sorted". Example 2) (this is a case of ...

I was playing around with Packet Tracer today, thought why not give it a try. Nice program none the less. So here is a very modest try on basic redistribution. I thought it will help someone. The lab had very basic set up, i used three routers and with a bunch of loopbacks i tested the redistribution between RIP and OSPF. You can use this lab as a tester or a reference point. PT lacks a lot of command options but is still very highly usable. So here is the setup: Router 1: (RIP V2) interface Loopback1 ip address 192.168.10.100 255.255.255.0 ! interface Loopback2 ip address 2.2.2.2 255.0.0.0 ! interface Serial0/0 ip address 172.16.10.1 255.255.255.252 ! router rip version 2 network 2.0.0.0 network 172.16.0.0 network 192.168.10.0 no auto-summary Router 3: (OSPF 1) interface Loopback1 ip address 3.3.3.3 255.0.0.0 ! interface Loopback2 ip address 192.168.20.100 255.255.255.0 ! interface Serial0/0 ip address 172.16.20.1 255.255.255.252 clock rate 64000 ! router ospf 1 log-adjacency-cha...

Hi, I am a CCNA and looking to recertify by taking the CCNA Wireless concentration as I would like to add some new knowlegde rather than just retake the current CCNA. I will need to know how to configure Cisco WCS, WLC's and AP's for the exam, so I am looking for a netsim like Boson's but for the Wireless config's only. Does a netsim for CCNA Wireless exist and if so what is it and how do I get it? Thanks.

Hello, I'm curious: what CCNA1 labs have you encountered so far? At CCNA1 I played with: - wireshark for packet capture - cain for interesting demonstrations - packet tracer for simulating networks - let's not forget the subnetting labs and wiring cables - another "lab" is playing a game like "Jeopardy" with questions from the it section What other interesting activities have you done so far on your CCNA1 classes? I'm looking for ideas to spice a little my CCNA1 class, so any crazy idea is very welcomed! Thanks in advance!
