STP Features In this section we will discuss on different improvement which added to the Rapid spanning-tree. In particular we talk about: Convergence Optimization Edge Port STP Filters BPDU Filter BPDU Guard Root Guard Unidirectional Link Detection Loop Guard Bridge Assurance Convergence Optimization Spanning-Tree Edge Port This is equivalent of PortFast feature with Common Spanning-Tree.

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 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 […]
In this post, I am going to configure Survivable Remote Site Telephony (SRST) between CUCM (site A) and a cisco router 2911 (Site B) for a call processing backup mechanism that allows IP phones to register when a WAN link is disconnected. Assume that the WAN link goes down, Cisco IP phones at site B should register to […]
