If you are thinking about doing the Cisco Wireless track then the CCNP Wireless is not one to take lightly. Announced in March 2016, CCNP Wireless still consists of four exams but have been revised to meet real world skills and demands. The expiring exams start with 640-XXX. The new CCNP Wireless exams are: 300-360…
Below are my notes for the CCNP Routing & Switching SWITCH 300-115 certification exam. I used two Cisco 3560 switches and GNS3 to perform my labs. For theory, I used Cisco Configuration Guides and the Cisco Press Official Certification Guide. Hot Standby Router Protocol, HSRP, is a Cisco proprietary protocol to make multiple routers or…
EtherChannel Guard is a way of finding out if one end of the EtherChannel is not configured properly. This could be that there are some parameters not matching up such as duplex and speed. Or it could be that one side is a trunk and the other isn’t. When there is a misconfiguration found, the…
Back when I was getting started in IT, Spanning Tree Protocol was a lightly touched upon topic. “Just remember it’s on by default and it does most of the work for you.” Most small networks won’t have to configure STP. If you’re planning redundant network links then you have to pay attention to STP. STP…
VLAN Trunk Protocol (VTP) is a Cisco-proprietary protocol used to replicate VLANs using Layer 2 trunk frames to other switches. It is a method to ease administration by selecting a switch to be configured as a VTP server. VLANs are configured on the VTP server and then replicated to other connected switches, called VTP clients….
[youtube http://youtu.be/uU1CRuuSBQo] A trunk will allow multiple VLANs to transport between switches. Trunk ports can be configured in two ways, the Cisco proprietary Inter-Switch Link, ISL, or with the standard IEEE 802.1Q Personally, I don’t use ISL and you shouldn’t either. But lets understand its differences with 802.1Q. Inter-Switch Link (ISL) ISL is Cisco proprietary in…
[youtube http://youtu.be/ppjHhL5lh3k] VLAN configuration is an objective for CCNP SWITCH 642-813 and CCNA 200-120. The following tutorial goes over the objectives: Implement VLAN based solution, given a network design and a set of requirements (CCNP SWITCH 642-813) Describe how VLANs create logically separate networks and the need for routing between them (CCNA 200-120) Configure and verify…
You get very excited once you get your own physical lab of routers and switches going. You just can’t wait to start managing and configuring switchport security, spanning-tree, etc. And then you get tired of having to move the console cable from one switch to the other. And you don’t have the ability to play…
VLANs are in every network environment. Whether you’re configuring end-to-end or local VLANs you are segmenting the network into logical groups. Before getting into the configuration of a VLAN, there are some best practices to be aware of: Avoid using VLAN 1. Put unused ports on an unused VLAN. I like to use VLAN 999….
