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 5Connect 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 6Next, view the routing protocols that are running on NYEDGE1. Connect to NYEDGE1 and 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.
