Hands-On Lab | CCNP: Building Cisco Multilayer Switched Networks Study Guide (642-811)

This lab will provide step-by-step instructions for configuring both access layer and distribution layer switches. You'll use a 2950 switch for the access layer and a 4000 series switch for the distribution layer. Figure 2.1 provides the network diagram that will be configured in this lab.

Configure the access layer switch by going to the console and pressing Enter.

Assign the console password:

 enable configure terminal line con 0 login password cisco

Assign the enable password:
```
 enable password sanfran 
```
Assign the enable secret, which will override the enable password:
```
 enable secret terry 
```
Set the hostname of the switch:
```
 hostname 2950 
```
Set the IP address of the switch:
```
 ip address 172.16.10.2 255.255.255.0 
```
Set the default gateway for the switch:
```
 ip default-gateway 172.16.10.1 
```

Set interface 4 to run in full-duplex mode:

 interface fastEthernet 0/4 duplex full

Set the description of the interface to Management PC:

 interface fastEthernet 0/4 description Management PC Control-Z

Type the command to view the current configuration:
```
 show running-config 
```
Verify the IP configuration of the switch:
```
 show ip int 
```
Verify the configuration of interface FastEthernet 0/4:
```
 show interface fastEthernet 0/4 
```

Configure the interface to full-duplex and add a description of Link to 4000:

 configure terminal (if needed) interface fa0/23 duplex full description Link To 4000

Configure interface fa0/24 to connect to the FastEthernet port 1/2 of the 4000 switch. Set the description and duplex as well:
```
 interface fa0/24 duplex full description Another Link to 4000 
```
Move your console cable to the 4000 series distribution switch. Set the hostname to be 4000:
```
 enable set system name 4000>
```

Set the user-mode and enable passwords:

 set password cisco set enablepass sanfran

Set the IP address of the 4000 switch:

 set interface sc0 172.16.10.4 255.255.255.0

Configure the port speed and duplex of the connection to the access-layer switch:
```
 set port duplex 1/1 full set port speed 1/1 100 
```
Set the description of port 1/1 to Link to Access Layer:
```
 set port name 1/1 Link to Access Layer 
```

Set port 1/2 as the second connection to the access layer switch:

 set port duplex 1/2 full set port speed 1/2 100 set port name 1/2 Link to Core Switch

Type the command to view port 1/1:
```
 show port 1/1 
```
Type the command to view the configuration of the 4000 switch:
```
 show config 
```
Test the connections by pinging all devices.
