The inside of a Cisco 1900-series switch. Catalyst is the brand for a variety of network switches, wireless controllers, and wireless access points sold by Cisco Systems.While commonly associated with Ethernet switches, a number of different types of network interfaces have been available throughout the history of the brand.
The Cisco Nexus series switches are modular and fixed port network switches designed for the data center. Cisco Systems introduced the Nexus Series of switches on January 28, 2008. The first chassis in the Nexus 7000 family is a 10-slot chassis with two supervisor engine slots and eight I/O module slots at the front, as well as five crossbar ...
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
The Cisco Supervisor Engine serves as the management card for modular Cisco switches that can also, in some cases, act as forwarding/routing element. [1]Over time, the Supervisor Engine has undergone multiple iterations and was different for different modular switches in Cisco Portfolio (Catalyst 4000, 4500, 5000, 5500, 6000, 6500, 9400, 9600 and Nexus switches).
An example of how to configure a simple, three switch MSTP topology wherein a layer-two access switch carries four VLANs and has two uplinks to two distribution switches, can be found here: MSTP Configuration Guide A good configuration view, from the above-mentioned example shall be: S3# show spanning-tree mst
In the Cisco IOS, [1] they are used in several places, for example: To indicate the size of a network or subnet for some routing protocols, such as OSPF. To indicate what IP addresses should be permitted or denied in access control lists (ACLs). A wildcard mask can be thought of as an inverted subnet mask.
Cisco had already issued a patch, but asked that the flaw not be disclosed. [18] Cisco filed a lawsuit, but settled after an injunction was issued to prevent further disclosures. [19] With IOS being phased out on devices, IOS-XE adopted many improvements including updated defaults. Some use cases can now store secrets as one-way hashes.
