Audiences: Candidates who want to prepare for CCIE Data Center (v3.0) Introduction to NX-OS Command Line In this section, we assume that you know how to connect to a NX-OS CLI via a terminal emulator program. Here is how we bootstrap our Nexus switch for the first time. If you skip Power On Auto Provisioning, […]
A Brief Introduction to MST IEEE 802.1s originally started as Cisco’s Multiple Instances Spanning Tree Protocol (MISTP). Remember that RapidPVST+ each VLAN is mapped to a single spanning tree instance. When you have 200 VLANs, it means there are 200 instances of spanning tree. This requires a lot of CPU power and memory. You can […]
A Brief Evolution of Spanning-Tree Protocols on NX-OS Before discussing on IEEE 802.1w, I would want to present a brief history of Spanning-tree evolution, the we continue with our main subject of this post. Spanning-tree is the loop prevention mechanism in Layer-2. According to graph theory: Spanning: A spanning graph is a subgraph obtained by […]
Audiences: Candidates who want to prepare for CCIE Data Center (v3.0) Scope: 1.1.b Tagging/Trunking from CCIE Data Center (v3.0) Exam Topics – Practical Exam Inter-VLAN Routing Although we can route between two VLANs with a router 802.1Q trunk (Router-On-A-Stick AKA ROAS), but that is not in the scope of our CCIE Data Center curriculum; instead, […]
Audiences: Candidates who want to prepare for CCIE Data Center (v3.0) Scope: 1.1.b Tagging/Trunking from CCIE Data Center (v3.0) Exam Topics – Practical Exam Virtual Local-Area Network (VLAN) You can take a physical LAN switch which does not break the broadcast domain and logically break it into multiple broadcast domains. You are doing this by […]
