Discover PC Configuration Information
Step 1: Access de pc die je zit en je command prompt.
Weet je niet in welk addres je zit doe op de pc in command promt: config /all.
Kan je je ip vinden en langzaam aan je netwerk discoveren.
Aan onderstaande informatie zie ik dus dat ik meerdere Default gateway's heb.
PC1:
ipv4 address: 10.2.15.10 ( Ip address van de pc)
Subnetnmask:255.255.255.0
Default gateway: 10.2.15.1 ( Dus de router in het netwerk is dan 10.2.15.1)
Router is altijd de default gateway.
PC2:
ipv4 address: 10.2.25.10
Subnetmask: 255.255.255.0
Default gateway: 10.2.25.1 ( 10.2.25 Netwerk)
PC3: ipv4 address: 10.2.35.10
Subnetmask: 255.255.255.0
Default gateway: 10.2.35.1 (10.2.35 Netwerk)
PC4:
ipv4 address: 10.3.100.4
Subnetmask: 255.255.255.0
Default gateway: 10.3.100.1 ( 10.3.100 Netwerk)
PC5: ipv4 address: 10.3.100.5
Subnetmask: 255.255.255.0
Default gateway: 10.3.100.1 (10.3.100 Netwerk)
PC6: ipv4 address: 10.4.1.10
Subnetmask: 255.255.255.0
Default gateway: 10.4.1.1 (10.4.1 Netwerk)
PC7:
ipv4 address: 10.5.1.10
Subnetmask: 255.255.255.0
Default gateway: 10.5.1.1 (10.5.1 Netwerk)
Documenteer dus echt je bevindingen ^^^^^^^^^^
From PC1, ping the default gateway to ensure that you have connectivity.
Zorg dat je altijd weet dat je de goede default gateway hebt.
Dit doe je door te pingen
In command promt op PC# ping je dus de default gateway:
Router is 10.2.25.1
Dus : Ping 10.2.25.1
( je router ^)
Use the telnet ip-address command. The IP address is that of the default gateway.
When prompted for the password type cisco.
Je Typt bij het commando Telnet je default gateway die je wilt zoeken.
Voor PC
Telnet 10.2.25.1 ( je router)
Password: Cisco
je wordt gevraagt het wachtwoord in tevullen ( in het examen staan deze links boven in of in de documenten)
Nu zie ik Router 3
Step 3: View current interface configurations.
a. Use both the show ip interface brief and show protocols command to determine
the current interface configurations.
De commando's hieronder ga je dus gebruiken om makkelijker het netwerk van de pc te zien:
op de pc's gaat het dus zo
command prompt op de pc
telnet Defaultgateway
Wachtwoord cisco/Cisco^
Commando's
Show ip interface brief:
laat je de poorten zien zoals Gig0/1, Ethernet0/1
Show protocols ( laat je protocollen zien )
Is bijvoorbeeld Protocol Routing ingeschakeld ( enabled)
Staat de poort aan of uit.
^^^^Dit zijn de commands die je moet weten
Verdere command's volgen.
Hiermee ga je dus het grootste wat je ziet documenteren
Part 4: Discover Routes and Neighbors in the Network
Step 1: On the gateway router for PC1,
display the routing table.
a.
Je gaat zometeen als je in de router zit of je zit er nog in een hoop shit aan poorten en info zien
enable
Show ip route
( laat je een hoop info zien) Ben er zelf nog niet uit wat ze nou willen
Kopieer alles wat je hier ziet staan in het,
vergeet niet te scheiden en goed uit te zoeken wat belangrijk is
Step 2: Discover directly connected Cisco devices.
On the gateway router for PC1, use the show cdp neighbors detail command to discover other
directly connected Cisco devices.
Om apparaten te zien die direct met Apparaat1/server te zien ga je op de pc
en zorg je dat je op de gateway van je pc zit
Voorbeeld:
telnet DefaultGateway*
show cdp neighbors detail
Zoek dan het volgende:
Interface: GigabitEthernet0/0.5, Port ID (outgoing port): FastEthernet0/5
Step 3: Document the neighbor information and test connectivity.
The show cdp neighbors detail command lists information for one neighbor, including its IP address.
Document the hostname and IP address of the neighbor, and then ping the IP address to test connectivity.
The first two or three pings fail while ARP resolves the MAC address.
Step 4: Telnet to the neighbor and discover directly connected Cisco devices.
a. Telnet to the neighbor and use the show cdp neighbors detail command to discover other directly connected
Cisco devices.
b. You should see three devices listed this time. The PC1 gateway router may be listed for each subinterface.
Note: Use the show interfaces command on the switches to determine the subnet mask information.
Step 5: Document the hostnames and IP addresses of the neighbors and test connectivity.
Document and ping the new neighbors you have discovered. Remember, the first two or three pings fail
while ARP resolves MAC addresses.
Step 6: Telnet to each neighbor and check for additional Cisco devices.
Telnet to each of the new neighbors you have discovered, and use the show cdp neighbors detail command
to check for any additional Cisco devices. The access password is cisco.
Step 7: Continue discovering and documenting the network.
Exit the Telnet sessions to return to the default gateway router for PC1. From this router,
Telnet to other devices in the network to continue discovering and documenting the network.
Remember to use the show ip route and show cdp neighbors commands to discover IP addresses you can use for Telnet.
Note: Use the show interfaces command on the switches to determine the subnet mask information.
Step 8: Repeat Steps 1 to 7 as necessary to discover the entire network topology.
Part 5: Draw the Network Topology
Step 1: Draw a topology.
Now that you have discovered all the network devices and documented their addresses,
use the Addressing Table information to draw a topology.
Hint: There is a Frame Relay cloud in the middle of the network.
Step 2: Keep this documentation.
a. Show your topology diagram and Addressing Table to the instructor for verification.
b. Your topology diagram and Addressing Table are needed for Part II of this activity.
Let op!!!!
als iets niet werkt of je snapt iets niet is het de fout van horizon
