Router> enable
Router# configure terminal
Router(config)# hostname NYEDGE2
NYEDGE2(config)# exit
NYEDGE2# show controllers serial 0/0/0
The output will be as follows:
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname NYEDGE2
NYEDGE2(config)#exit
NYEDGE2#show controllers serial 0/0/0
Interface Serial0/0/0
Hardware is SCC
DCE V.35, clock rate 2000000
idb at 0x21ADADC0, driver data structure at 0x3C2D47A0
wic_info 0x21ADBCD0 NYEDGE2#show controllers serial 0/0/0
!<-- Output Omitted -->
NYEDGE2#
Step 5
Connect to NYWAN1. Quit the initial configuration dialogs on routers by typing no and issue the following commands (press Enter after each command):
Router> enable
Router# configure terminal
Router(config)# hostname NYWAN1
NYWAN1(config)# exit
NYWAN1# show controllers serial 0/2/0
You will see the following output:
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname NYWAN1
NYWAN1(config)#exit
NYWAN1#show controllers serial 0/2/0
Interface Serial0/2/0
Hardware is SCC
No serial cable attached
idb at 0x3C818878, driver data structure at 0x21F2DAA8
wic_info 0x3C819788NYWAN1#show controllers serial 0/2/0
!<-- Output Omitted -->
NYWAN1#
In the output of NYEDGE2, you can see that there is a DCE cable attached, and on NYWAN1, there is no cable attached. This gives you all three possible outcomes of this command: DTE, DCE, and no cable. If you look at the picture at the start of the module, you will see that there is no cable attached to Serial 0/2/0. This is also confirmed by the output.
Step 6
Next, view the routing protocols that are running on NYEDGE1. Connect to NYEDGE1and enter the following command:
NYEDGE1# show ip protocols
Press Enter.
You will see the following output:
NYEDGE1#show ip protocols
*** IP Routing is NSF aware ***
NYEDGE1#
As you can see, there are currently no routing protocols enabled; this is, of course, the case as the router was powered up in a fresh, un-configured state.
