Now, you can easily migrate your PIX configurations to ASA configuration for your new devices. Find out how to do it, step by step, in my new articleL Converting from old to new with the PIX to ASA Migration Tool

7 Windows & Cisco commands for network troubleshooting

David Davis David Davis Profile: David Davis

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:

  1. 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.
  2. 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.
  3. 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).
  4. 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.

Happy Troubleshooting!
