6-DC/Basic Layer 2 Operation and Features on Nexus switches Part 1.

In this post i will talk about some of basic features and technologies supported by Nexus switches that depend on layer 2 operation, so i will talk about their operation, configuration and verification commands from CLI point of view, while i will talk about the other features in the next post. Layer 2 operation on … Continue reading 6-DC/Basic Layer 2 Operation and Features on Nexus switches Part 1.

5-R&S/Virtual LAN Trunking Protocol (VTP).

In this post i will talk about how can we advertise the VLAN database information in dynamic way, using VTP, so in this post i will talk about its operation, versions, configuration and its verification commands from CLI point of view. Virtual LAN Trunking Protocol (VTP): Assume that we have Layer 2 switched network, and … Continue reading 5-R&S/Virtual LAN Trunking Protocol (VTP).

4-R&S/Multiple Spanning Tree Protocol (MST).

Let's continue the previous three posts 1-R&S/Virtual LAN (VLAN) and Spanning Tree Protocol (STP) , 2-R&S/Spanning Tree Protocol (STP) Part 2. and 3-R&S/Spanning Tree Protocol (STP), RSTP Part 3, so in this post i will talk about the last protocol defined to avoid the loop in the Layer 2 switched network, which is the Multiple Spanning … Continue reading 4-R&S/Multiple Spanning Tree Protocol (MST).

3-R&S/Spanning Tree Protocol (STP), RSTP Part 3.

Let's continue the STP explanation at the previous two posts 1-R&S/Virtual LAN (VLAN) and Spanning Tree Protocol (STP) and 2-R&S/Spanning Tree Protocol (STP) Part 2., in this post i will mention Rapid Spanning Tree (RSTP) and some configurations and verification commands related to RSTP, and i will mention MST in the next post. Rapid Spanning Tree (RSTP) … Continue reading 3-R&S/Spanning Tree Protocol (STP), RSTP Part 3.

2-R&S/Spanning Tree Protocol (STP) Part 2.

Let's continue the STP explanation at the previous post 1-R&S/Virtual LAN (VLAN) and Spanning Tree Protocol (STP), in this post i will mention the different modes and protocols of STP as well some configurations related to STP. At the previous post i stopped at the criteria used by the STP to elect the Root bridge … Continue reading 2-R&S/Spanning Tree Protocol (STP) Part 2.

1-R&S/Virtual LAN (VLAN) and Spanning Tree Protocol (STP).

In this post i will talk about Virtual LAN (VLAN) and Spanning Tree Protocol (STP) and its main purpose and why we use them in our switched network. Virtual LAN (VLAN): All of us know what is the Local Area Network LAN, simply as the name implies, the LAN is considered as a group of … Continue reading 1-R&S/Virtual LAN (VLAN) and Spanning Tree Protocol (STP).
