arp, ipconfig, ping, traceroute, tracert, troubleshooting
To Troubleshoot Cisco and Windows networks, you need to know command equivalents. Cisco and Windows commands are similar but not identical.
Here are 7 Windows and Cisco commands that you should know:
- ping- used both in Windows and in the Cisco IOS to verify connectivity from of to a router (default gateway) and from a router to a PC.
- traceroute or trace in the Cisco IOS or tracert in Windows – used to trace the path your network traffic takes to a destination (like the web server you are trying to access) or from your router to a downstream router.
- arp -a in Windows or show ip arp in the Cisco IOS – used to verify Layer 2 to Layer 3 mappings (aka Ethernet to TCP/IP) or Ethernet MAC Address to IP Address (and vice versa).
- ipconfig /all in Windows or show ip interface brief in the Cisco IOS – used to show the IP address configuration for your NIC on your PC or for your router’s LAN/WAN interfaces. This output would include the IP Address, Subnet Mask, Default Gateway, and (on a PC), even the DNS Servers.
These are all pretty basic commands but they are all necessary commands that you must know to troubleshoot Windows and Cisco Networking.
