Theoretical learningproblem 1 : How does the switch work? By learning the computer MAC address of each interface, it realizes the data communication of each computer, and the routing table of the router is similar, the switch is realized by the Mac-port mapping table.problem 2 : Two layer switch, three layer switch, router difference? Two-layer switch: For switching, LAN, WAN switching onlyLayer Three switch: Also known as the routing switch, with the dual functions of routing and switching, onl

Introduction to catalyst vmps: This article introduces VMPS Technology in three modes: VLAN unspecified on the port and VLAN already specified on the port. How can I configure dynamic VLANs and VMPS for CATALYST 4500 series switches? This article takes cisco ios 12.2 (31) SGA as an example. VMPS introduction: VMPS introduces the abbreviation of VLAN Membership Policy Server. as the name suggests, it is a ce

The previous articles explained the core execution process of spark SQL and the SQL parser of the Catalyst Framework for Spark SQL to accept user input SQL, parsed to generate unresolved Logical plan. We remember another core component analyzer in the execution process of Spark SQL, and this article will describe what the analyzer does in spark SQL.Analyzer is located under the Catalyst's analysis package, and the main responsibility is to resolved ou

Table of NAT features supported by Catalyst series switches 　 Note: The ipvs4000/4500 series switches of sup3/4 support the AGW module from 12.1 (13) EW. When the AGW module runs IOS 12.2 (13) T and later versions, you can use the AGM module to support NAT. In this case, NAT is implemented in software mode. NAT on MSFC and MSFC2 of ipvst6000/6500 is supported by software. When the NAT feature is enabled on vswitches of the 6500 series,

Why won't some successful people or organizations become automaticallyVerySuccess? An important explanation of this problem is the "objective-specific paradox", which can be summarized into four stages: Phase 1: when we have a clear goal, it will make us succeed. Phase 2: When we succeed, we will be given more choices and opportunities. Phase 3: when we have more options and opportunities, these opportunities will distract us from our efforts. Phase 4: when our efforts are dispersed, the cl
