POSTMAN API: LABORATORY 

TASK 1: SET IP ADDRESS ON YOUR VIRTUAL MACHINE. 

1. Open VMWARE -> File -> Open -> locate RIVAN APPS -> IOS -> CSR1000v -> Open

2. Assign a name for your virtual machine and password. 

   Router name: CSR1000v
   Router username: admin 
   Password: pass

3. Before Powering on make sure the default network adapter 2 is set to NAT. 

4. Power ON the virtual machine. Press any key to continue. 

5. Type in the following commands: 

	en (for enabling) 
	sh ip int br (there should not be an ip address assigned since we did not set an 
	               ip address. 
				   
    COMMAND TO ASSIGN AN IP ADDRESS: 
	
	conf t 
	int gi2
	ip add dhcp 
	no shut 
	
	**wait for your virtual machine to notify you that ip DHCP has been up**

	CHECK IF THERE'S an IP ADDRESS ASSIGNED ON YOUR GIGABIT 1. 
	
	COMMAND: 
	sh ip int br OR do sh ip int br
	

6. Once you have seen that there is an IP Address already, open your CCNA Desktop 
   Folder and locate the file named DEVOPSCrashCourse that is located on the bottom
   and edit with notepad ++.
