CCENT Concepts Pt. 10 Flashcards
ADSL
Asymmetric digital subscriber line. One of many DSL technologies, ADSL is
designed to deliver more bandwidth downstream (from the central office to
the customer site) than upstream.
ATM
Asynchronous Transfer Mode. The international standard for cell relay in
which multiple service types (such as voice, video, and data) are conveyed in
fixed-length (53-byte) cells. Fixed-length cells allows cell processing to occur
in hardware, thereby reducing transit delays.
Configure HDLC
- Configure the interface IP address using the ip address interface
subcommand. - The following tasks are required only when the specifically listed conditions
are true:
a) If an encapsulation protocol interface subcommand that lists a protocol
besides HDLC already exists on the interface, use the “encapsulation hdlc”
interface subcommandto enable HDLC.
b) If the interface line status is administratively down, enable the interface
encapsulation { hdlc | ppp | framerelay
}
Serial interface subcommand that
defines the data-link protocol to use on
the link.
clock rate [speed]
Serial interface subcommand that,
when used on an interface with a DCE
cable, sets the clock speed in bps.
bandwidth [speed-kbps]
Interface subcommand that sets the
router’s opinion of the link speed, in
kbps, but has no effect on the actual
speed.
description [text]
Interface subcommand that can
set a text description of the
interface.
Configure HDLC
- Configure the interface IP address using the ip address interface
subcommand. - The following tasks are required only when the specifically listed conditions
are true:
a) If an encapsulation protocol interface subcommand that lists a protocol
besides HDLC already exists on the interface, use the “encapsulation hdlc”
interface subcommandto enable HDLC.
b) If the interface line status is administratively down, enable the interface
show ip nat translation
Lists the NAT/PAT translation
table entries.
encapsulation { hdlc | ppp | framerelay
}
Serial interface subcommand that
defines the data-link protocol to use on
the link.
show dhcp server
Lists information learned from a DHCP
server, by a router acting as a DHCP
client.
clock rate [speed]
Serial interface subcommand that,
when used on an interface with a DCE
cable, sets the clock speed in bps.
clear ip nat translation *
Lists several important settings on serial links,
including encapsulation, bandwidth, keepalives, the
two status codes, description, and IP address/mask
bandwidth [speed-kbps]
Interface subcommand that sets the
router’s opinion of the link speed, in
kbps, but has no effect on the actual
speed.
show controllers serial [number]
Lists whether a cable is connected to
the interface, and if so, whether it is a
DTE or DCE cable
