Difference between a normal Cisco Switch and a Catalyst

Image
Heyy guys!!! You might have heard the name Catalyst Switch or L-3 Switches and you might have a lot of confusion regarding it. so today we will discuss about the difference between a normal Cisco Switch and a  Catalyst  Switch. Catalyst is the brand-name of Cisco’s most popular series of switches. When someone says they’re using a “Catalyst switch”, it just means that they’re working with a Cisco switch. Other companies have names for their L-3 switches, like HP’s ProCurve or Dell’s PowerConnect. A Layer 2 switch (L-2) does switching only. This means that it uses MAC addresses to switch the packets from a port to the destination port (and only the destination port). It therefore maintains a MAC address table so that it can remember which ports have which MAC address associated. A L3 switch also does switching exactly like a L2 switch. The L3 means that it has an identity from the L3 layer. Practically this means that a L3 switch is capable of having IP add...

HOW TRACEROUTE WORKS

Well guys !! Time to take a break from our regular Ethical Hacking posts and learn something new in Networking. You guys might have used  “traceroute”  command   many  a times but have you ever wonder how this works? Lets see when we press  ENTER after the above command than what happens at the BackEnd. Traceroute sends a sequence of UDP packets ( these may be ICMP packets as well ). Traceroute uses TTL value to determine intermediate routers that comes in between the Source and Destination. The device decreases the TTL value to 1 and sends it to the Destination. Now what happens when first time the device (Router, PC or Switch) sends the the ICMP packet it sets the TTL value of the packet to 1 (means max. HOP COUNT for that packet will be 1) and as soon as a device recieves a UDP or ICMP packet it decreases its value by 1. so the packet will not be send to the next HOP and reply comes from the first HOP and the device writes the entry on the C...
