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 command reports the round-trip times of the packets received from each successive host (remote node) along the route to a destination. The sum of the mean times in each hop is a measure of the total time spent to establish the connection. The command aborts if all (usually three) sent packets are lost more than twice.
Dividing a value of 10 7 kbit/s (i.e. 10 Gbit/s) by the interface bandwidth statement value yields a result that is used in the weighted formula. The interface delay is a configurable static parameter expressed in tens of microseconds. EIGRP takes this value directly without scaling into the weighted formula. However, various show commands ...
The network address and subnet mask of the interface, along with the interface type and number, are entered into the routing table as a directly connected network. A remote network is a network that can only be reached by sending the packet to another router. Routing table entries to remote networks may be either dynamic or static.
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.
This is known as inter-VLAN routing. On layer-3 switches it is accomplished by the creation of layer-3 interfaces (SVIs). Inter VLAN routing, in other words routing between VLANs, can be achieved using SVIs. [1] SVI or VLAN interface, is a virtual routed interface that connects a VLAN on the device to the Layer 3 router engine on the same device.
The Nexus 9000 series is a range of many models 2U to 21U rack-switches offering 60 to 2304 interfaces running on 100Mb, 1Gb, 10Gb, 25Gb, 40Gb, 100Gb, 400Gb Ethernet, 10/25/40 Gb FCoE interfaces. They can be used with the above-mentioned Nexus 2000 series fabric extender.
Wireless tools for Linux is a collection of user-space utilities written for Linux kernel-based operating systems to support and facilitate the configuration of device drivers of wireless network interface controllers and some related aspects of networking using the Linux Wireless Extension.
