Deploying the Dell Force10 MXL into a Cisco Nexus Network Environment54Appendix B: Basic TerminologyBridgingBridging—commonly called switching—is frame-by-frame layer-2 forwarding of Ethernet traffic withforwarding decisions generally based on each frame’s source and destination MAC address. A simplebridge has three available actions to perform on received traffic—filter, forward, or flood. An Ethernetbridge is very simple and relies on bridging protocols like spanning-tree to not send data frames in aloop, causing a storm.Channel GroupSee LAG.CLICommand Line Interface (CLI) is the text-based console interface that is used for entering managementand configuration commands into devices like the Dell Force10 MXL switch. The MXL’s CLI can beaccessed via telnet, SSH, an externally-accessible serial connection, and also from the CMC’s CLI.CMCChassis Management Controller (CMC) is the embedded management interface of the Dell PowerEdge™M1000e blade server chassis. Among other functions, the CMC provides network and console access toinstalled IO modules including the Dell Force10 MXL switch.Filter, Flood, ForwardData frames received by Ethernet switches may be filtered (meaning discarded or dropped) accordingto defined behavior, automatic protocols, or administrative configuration; flooded (meaning sent outall other links) if the data frame’s destination MAC address is unknown; or forwarded (meaning sent toone other link) if the destination MAC address is already learned. A destination for a MAC address maybe manually configured on a link’s interface; but, most MAC address destinations are learneddynamically based on source MAC addresses of already received data frames—when a bridge receives adata frame, it remembers the source MAC address of the frame on the received link for five minutesand will then selectively forward data frames destined for that MAC address over that link as a learneddestination.IOMIO module (IOM) refers to the modules at the rear of the Dell PowerEdge M1000e chassis that willreceive and transmit I/O (Ethernet, FC, Infiniband, etc.) from the blade servers located at the front ofthe chassis. The Dell Force10 MXL switch is as an IOM for the M1000e blade server chassis.LACPLink Aggregation Control Protocol (LACP) is the protocol used to ensure that the multiple links in a LAGdo not form loops due to misconfiguration or device misbehavior. It is recommended practice to alwaysuse LACP on configured LAGs.
