UGRD-IT6223 Data Communications and Networking 2
(Cisco 2) is all about network routing and switching essentials. In this course you will have a clear understanding in what are routers, and switches are all about and its purpose. Also in this course we’ve prepared for you well suited laboratory exercises for you to gain knowledge and skills in configuring these devices in different scenarios and in different networking environments. In between you will have some tips or pointers for you to make things easier. This course will not just help you to understand topics easier but prepare you in the real life networking environment and help you in passing some Cisco certification exams. For this course, it is essential at least you have a basic background in networking and you need to download Cisco Packet Tracer Student software as your simulation tool for the labs.

inter-VLAN routing. A trunk is configured to connect the switch to the
router. Whatis the minimum number of router subinterfaces that are required
for all the VLANs to communicate? |

blinking green what is the status of switch? |

Double Tagging Attack |
This type of attack takes advantage of the way
that hardware on most switches operates. Most switches perform only one level
of 802.1Q de- encapsulation, which allows an attacker to embed a hidden
802.1Q tag inside the frame. |
|
Telnet DoS attack |
In this attack, the attacker exploits a flaw in
the Telnet server software running on the switch that renders the Telnet
service unavailable. This sort of attack prevents an administrator from
remotely accessing switch management functions. This can be combined with
other direct attacks on the network as part of a coordinated attempt to
prevent the network administrator from accessing core devices during the
breach. |

servers and to make the clients use the attacker, or a machine under the
control of the attacker, as their default gateway. |
