How to find loops on an access switch
We will show you how to detect routing loop and physical loop with a network analyzer such as Colasoft Capsa or Wireshark. Switching loops occur when network switches are connected together in such a way that network traffic loops around infinitely instead of traversing the hops needed to travel from source to destination. They can take down an entire network. Our topo at a site goes WAN rtr---LAN rtr (6500 of 3550)----distro switches----access switches. Now at most of our sites we use Extreme, which has a handy feature called ELRP Extreme Loop Recovery Protocol, despite the name, this mechanism just detects loops, in the logs we can see, ok. The strict mode is based on interface and loose mode based on VLAN. There is also of course the way to get a hard proof by using Wireshark and a packet capture to check if one and the same frame is appearing with a.

Case Analysis of Line Relay Protection
This paper analyzes the basic principle and function of relay protection, summarizes the common fault types, and analyzes the fault analysis methods and treatment measures combined with actual cases. Its primary role is to detect and isolate faults occurring on overhead lines or underground cables. Abstract—Short transmission lines connected in a looped configuration are typical of some industrial power systems, but they can present numerous protection coordination difficulties because of their inability to effectively use underreaching elements. The results show that the reliability of relay protection devices can be improved by means of. Abstract—This case study presents the working, testing and commissioning of the 220 kV backup distance protection schemes employed on the Pipri West Grid of Karachi Electric Limited (KEL).

Comparison of Low-Loss Performance of Access Switches
In this paper, we propose a methodology intended to be fair and use it to compare the performance of seven state-of-the-art software switches. Definition: Switch throughput, or throughput rate, is the most important measure of network switch performance. It's defined as the maximal forwarding speed without loss of packets, typically measured in the form of packets each second (PPS/FPS) or bytes per second (bit/s Mbit/s, Gbit/s). It is. Software switches are increasingly used in network function virtual-ization (NFV) to route trafic between virtualized network functions (VNFs) and physical network interface cards (NICs).
