Networks
Data transmission
Type of topology that refers to arrangement of the cables, network devices, and end systems; it describes how the network devices are actually interconnected with wires and cables
Type of topology that describes the path over which the data is transferred in a network and how the network devices appear connected to network users
measure of the data rate in bits per second (b/s) of a given link in the network
Speed
Manually configure the IP address, subnet mask, default gateway and probably the DNS server IP address.
Dynamically
Statistically
IP address information is obtained from a Dynamic Host Configuration Protocol (DHCP) server. • DHCP server provides an IP address, subnet mask, default gateway and probably the DNS server information.
Dynamically
Statistically
RJ-45 to DB-9 serial cable or a USB serial cable.
Terminal emulation software
Console cable
Tera Term, PuTTY, or HyperTerminal
Terminal emulation software
Console cable
require IP addresses in order for the network administrator to connect to the devices using Telnet, SSH, HTTP, or HTTPS.
MAC addresses
Network devices
IP addresses
requires an IP address to be configured on a virtual interface, called the switched virtual interface (SVI).
Switch
Network Devices
Commands
Displays a summary for all interfaces including the IPv4 address of the interface as well as the current operational status.
show ip interface brief
show ip route
show running-config interface interface-id
Displays the contents of the IPv4 routing table.
show ip interface brief
show ip route
show running-config interface interface-id
Displays the commands configured on the specified interface.
show ip interface brief
show ip route
show running-config interface interface-id
Displays interface information and packet flow counts.
show interfaces
show ip interface
Displays the IPv4 related information for all interfaces on a router.
show interfaces
show ip interface
If the destination IP address belongs to a network that is directly connected to the router, the packet is forwarded out of that interface.
Directly connected network
Remote network
No route determined
– If the destination IP address of the packet belongs to a remote network, the packet is forwarded to another router
Directly connected network
Remote network
No route determined
If the destination IP address does not belong to a connected network or is in the routing table, the packet is sent to Gateway of Last Resort.
Directly connected network
Remote network
No route determined
Obtained from the active router interfaces.
Directly connected routes
Remote routes
These are remote networks connected to other routers that are learned from dynamic routing protocols or are statically configured.
Directly connected routes
Remote routes
