welcome to packet tracer five point
three point two point eight examine the
art table objectives part one examine
our per quest part to examine a switch
MAC address table part three examine the
art process and remote communications
background this activity is optimized
for viewing PD use the devices are
already configured you will gather PDU
information simulation mode answer a
series of questions about the data that
you collect part 1 examine an arp
request step 1 generate ARP requests by
pinging 172 16 31.3 from 170 to 1630 1.2
so click 1 7 2.16 got ready 1 2
open the command prompt desktop enter
our PhD commands clear the ARP table
okay now
[Music]
into simulation mode and enter the
command p17 2.16 31.3
[Music]
to PDUs we generated the ping command
cannot complete the ICMP packet without
knowing the MAC address of the
destination so the computer sends an ARP
broadcast frame define the MAC address
of the destination click capture forward
once the ARP PD you loose switch 1 while
the ICMP PDU disappears waiting for the
ARP reply open the PDU
and record the destination MAC address
[Music]
is this address listed in the table
above
[Music]
notice nothing it's not there
click capture forward to move the PDO to
the next device how many copies the pvu
to switch one make one two three what is
the IP address of the device that
accepted the PDU this one right here and
that would be 170 2.16 31.3 open the PDU
and examine layer 2 what happened to the
source and destination MAC address the
source MAC destination MAC address timed
out click capture forward to the PDU
returns 2 1 7 2016 3000 ft
[Music]
how many copies of the PDU this which
make during our reply that be one
step two examine the carp table note
that the ICMP packet appears open the PD
you examine the mag address do the MAC
addresses of the source and destination
aligned with the IP addresses yes it
does
switch back to real-time and pain the
and the pain completes click 172 1631 to
and enter arp - a command
to what IP address does the MAC address
entry correspond this is a MAC address
and this is the IP address
in general Linda's end device issued our
request when it does not know the
receivers MAC address
[Music]
part-2 examiner switch MAC address table
step 1 you generate additional traffic
to populate the switch MAC address table
from 172 1631 to enter the ping 172 da
system 31.4
[Music]
click 10-10-10 to open the command
prompt
[Music]
enter the pain 10.10.5.3
[Music]
how many replies were sent and received
4% and received step 2
[Music]
examine the MAC address table on the
switches click switch 1 and then the CI
tab enter the show MAC address table
command
[Music]
- the entries correspond to those in
table above
[Music]
yes
click switch zero and they see light
into the show mechanistic Amanda
[Music]
do the entries correspond to those in
the table show
[Music]
yes they do
why are two MAC addresses associated
with one port because both devices
connect to one port through the access
point part 3
[Music]
examine the art process and remote
communications
[Music]
step1 generate traffic to produce arc
traffic click 172 1631 to an open
command prompt
[Music]
enter the pain 10/10 10.1 command type
ARP - a what is IP address the new ARP
table entry the new MAC address would be
right here this is the new one this IP
address
[Music]
enter ARP - D - clear the ARP table and
switch to simulation mode
[Music]
repeat the ping through 10 10 10 1 how
many PDUs appear
[Music]
to click capture forward click the PDU
that is now switch one
[Music]
what is the target destination IP
address of our per quest the new
destination would be
right here 172 got 1.1 which is
right here
[Music]
the destination IP address is not 10.10
10.1 why it times out it step to examine
the ARP table our router 1 switch to
real-time mode click router 1 and CLI
enter privileged exec mode and then show
MAC address table
[Music]
how many MAC addresses are in a table
and why there are zero MAC addresses in
the table and because it times out
just know that Christmas enter the show
art command
is there an entry for 172 16 31.2 yes
what happens to the first ping in a
situation where the router responds to
the ARP request it times out and we are
all done thank you again for watching
the pack of tracers and I'll be
uploading some more later so please hit
subscribe so you'll be informed of when
I upload these I usually upload about
two or three a week thank you again for
watching ultimate tech hub
[Music]
[Music]
you
