Connecting to a Host

· If possible, use pods 7-10. They have devices capable of running SDM.

· Each pod has a connection on CAT1 port FastEthernet0/18 to an access server that manages the hosts in the lab.

· The hosts are numbered 1 – 16.

· Each host has two network adapters. One is connected to RPI’s public network, and the other is connected to a private VLAN.

· The IP addressing scheme is as follows:

How to connect:

1) Configure FastEthernet0/18 on CAT 1 to trunk VLAN 900 + X where X is the number of the host you have chosen (you do not need to use the same host number as your pod number). You may also allow multiple VLAN’s on the trunk if you need to connect to more than one host.

switchport trunk allowed vlan 900 + X

switchport mode trunk

2) Make sure that interface FastEthernet0/18 is up. If not, ask a TA.

3) Remote Desktop into the host you have chosen using the IP address of the public interface shown above.

· Username: administrator

· Password: lmi

You are now connected to the host’s public interface, but there are further configurations necessary to get the host communicating with your pod (SDM will not work yet).

Example

In order to connect pod 8 to Host 9, you would need to configure CAT 1 to trunk VLAN 909 on interface FastEthernet0/18. You can then connect to Host 9 using Remote Desktop with an IP address of 128.213.10.109.

4) Now check to see if the host has already has an IP address configured.

a. You can check by showing the host’s network connections.

b. Start > Control Panel > Network Connections > VLAN 900 + X

c. If there is already an address configured, you can use that, otherwise choose an address now. Do not configure a default gateway, or you will lose connectivity to your host.

Example

5) Next, you must configure R2’s port that connects to CAT 1 with an IP address in the same subnet as the host’s private VLAN IP address. Make note of the IP address you choose, you will need it later as the gateway address.

6) Once the host and R2 are in the same subnet, you must ensure they are in the same VLAN. To do this, configure port FastEthernet0/2 on CAT 1 as an access port in VLAN 900 + X. Now that the host and R2 are in the same subnet and VLAN, and since they are directly connected, they should have full connectivity. Ping to test.

switchport access vlan 900 + X

switchport mode access

7) At this point, the host can only reach R2, and SDM can be used on R2 only. Before connecting to SDM however, you must create a username and password (with privilege level 15) on the router.

username _______ privilege 15 password ________

ip http authentication local

8) If you need the host to connect to any other devices in the pod, you must add routes to the private networks that the devices are on using the route add command.

a. Open a DOS prompt.

b. Use the command: route add <destination network> MASK <network mask> <gateway>

c. For the gateway, use the IP address of the next hop router (in our case this will always be the IP address you configured on R2).

9) When finished, always shut FastEthernet0/18 on CAT 1 to limit traffic between pods.
