catalyst 9300

There are many users who use Cisco switches. When selecting their products, it is a headache to see Cisco switch models. Here we mainly explain how to quickly understand these complex Cisco switch models. The product line of the 2900 series is very long. Some of them are common 10/100 BaseTx Cisco switches, such as C2912 and C2924, some are with Optical Fiber interfaces, such as C2924C with two 100 BaseFx ports, and some are modular, for example, C 2924 M has two expansion slots. The expansion s

Such a person will help the team shape and unite, maintain the health and productivity of the team, and thus contribute to the project. Even if "Catalyst" does nothing (in fact, they usually do many o

point1. Cannot be modified after creation: Spark emphasizes immutability, and in most scenarios tends to create new objects instead of modifying old objects. 2. By viewing data manipulation records, you can efficiently recalculate lost data. 3. Support for the operation of distributed data. Both 4.DataFrame and RDD can be created from the following data sources: (1) A Python dataset for distributed storage. (2) Dataframe or other spark datasets in pandas. (3) files in HDFs or other file syste

A. About stacking technology: How does the 1.Catalyst 3500XL/2900XL stack be implemented? A. Special tiered cabling is required, 1 m long or 50 cm long (cab-gs-1m or cab-gs-50cm) and a dedicated gigabit stacked card Gigastack GBIC (WS-X3500-XL) (which already contains cab-gs-50cm stacked cables). B. There are 2 stacking methods available: Daisy Chain (providing 1G of bandwidth) or point-to-point method (2G bandwidth available). C. 2 ways to do back
