View the routers interfaces View which cables are connected to the routers WAN interfaces (the cards that are inserted in to the HWIC slots) View which routing protocols are running on the router View which IOS version the router is running
Step 1 First let’s configure the hostname of the router. As you powered on NYEDGE1, let’s configure the hostname accordingly. In the same way you did the switch in a previous module, enter global configuration mode and use the hostnamecommand to set the routers hostname: Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname NYEDGE1 NYEDGE1(config)# Step 2 Next we’ll have a look at which interfaces the router has, andon the serial interfaces we’ll check whether there are any cables attached or not. Being able to view which cables are attached to the serial interfaces (WIC-1T or WIC-2T in the lab) is very handy, it can be a great way to troubleshoot connectivity issues. Quit out of global configuration mode, and use the show ip interface briefprivileged mode command to get a summary view of the interfaces: NYEDGE1(config)#exit NYEDGE1# *Jun 2 16:14:36.127: %SYS-5-CONFIG_I: Configured from console by console NYEDGE1# NYEDGE1#show ip interface brief Interface IP-Address OK? Method Status Protocol Embedded-Service-Engine0/0 unassigned YES unset administratively down down GigabitEthernet0/0 unassigned YES unset administratively down down GigabitEthernet0/1 unassigned YES unset administratively down down GigabitEthernet0/2 unassigned YES unset administratively down down Serial0/0/0 unassigned YES unset administratively down down Serial0/0/1 unassigned YES unset administratively down down NYEDGE1# In the output you can see that NYEDGE1 has a two serial interfaces, this can be confirmed if you observe the images at the start of this module.
Step 3 Let’s have a look at what type of cable is connected to the serial interface. To do this, you can use the show controllersprivileged mode command, we’ll focus on the serial 0/0/0interface NYEDGE1#show controllers serial 0/0/0 Interface Serial0/0/0 Hardware is SCC DTE V.35 Clock Freq detected Rx clk/Tx clk 1932734/1932734 (+-10%) (Output omitted) Whilst it is not entirely obvious from the lengthy output that results from the command, in the first few lines you will see DTE V.35 starting at the beginning of one of the lines. This indicates that a DTE cable is attached to the interface. Connect to NYEDGE2 and NYWAN1 and compare the output from this command (quit the initial configuration dialogs on both). On NYEDGE2 you will see (Note:I have set the hostnames for ease of reference in the outputs below): NYEDGE2#show controllers serial 0/0/0 Interface Serial0/0/0 Hardware is SCC DCE V.35, clock rate 2000000 (Output omitted) On NYWAN1, use serial 0/2/0, if you look at the picture at the start of the module you will see that
