CCNP Switch: Switch Port Configuration Ethernet Concepts This section reviews the varieties of Ethernet and their application in a campus network. Recall how the bandwidth requirements for each network segment are determined by the types of applications in use, the traffic flows within the network, and the size of the user community served. Ethernet scales to support … [Read more...]
CCNP Switch: Switch Configuration
CCNP Switch: Switch Configuration Switch Management Managing a Catalyst switch can be broken up into several topics. A switch runs an operating system, which provides a user interface and controls all processes that are used to forward packets. The following sections address all these topics. Operating Systems You can configure Cisco Catalyst switch devices to support many … [Read more...]
CCNP Switch: Switch Operation
CCNP Switch: Switch Operation Layer 2 Switch Operation Recall that with shared Ethernet networks using hubs, many hosts are connected to a single broadcast and collision domain. In other words, shared Ethernet media operate at OSI Layer 1. Each host must share the available bandwidth with every other connected host. When more than one host tries to talk at one time, a … [Read more...]
