An EtherChannel (or port group) is a group of two or more Fast Ethernet or Gigabit Ethernet switch ports bundled into a single logical link, creating a higher bandwidth link between two switches. Each EtherChannel can consist of up to eight compatible, configured Ethernet ports. The switch supports up to six EtherChannels.
With Flex Links, you define an active uplink interface and a backup uplink interface. The figure below shows the process by which Flex Links converge a redundant star topology.
Resilient Ethernet Protocol (REP) is a technology implemented on Cisco distribution switches and Cisco IE and Rockwell Automation Stratix IES. REP is designed to provide fast network and application convergence in case of a media or network failure, without a negative impact on most network applications.
Device Level Ring (DLR) is an EtherNet/IP protocol that is defined by the Open DeviceNet Vendors’ Association (ODVA). DLR provides a means to detect, manage, and recover from single faults in a ring-based network.
First things first – lets define “short-range” for this article. By short-range wireless, we are discussing wireless connectivity within 400 meters. This typically utilizes Bluetooth or Wireless LAN (WLAN)/WiFi technology. We will discuss longer-range industrial wireless solutions in an upcoming post. Also, to help narrow our focus, we […]
