Learning has never been so easy!
As a Network Administrator/Engineer you may be asked to find MAC addresses and/or IP Addresses, hopefully this can make your job a little bit easier. These commands work on most Cisco Switches and Routers but sometimes the commands can vary from device to device.
5 Steps totalStep 1: Connect to your Cisco DevicesCisco Connect Software Mac Yosemite Update
Connect to the Switch/Router by using a console cable or a terminal emulator like Putty or Secure CRT. If you are successful it should look something like this.
Step 2: Find The MAC Addresses
On the layer 2 device (switch) enter the username and password if needed. Next enter 'enable' mode on the switch by typing enable. Next type the command 'show mac address-table'. If successful it should look like the picture. It's worth noting that on some Cisco devices the command 'show mac-address-table' also works.
Step 3: Find the IP Address
On the layer 3 device ( L3 switch or router) in my case I am using a router, enter the username and password if needed. Next enter 'enable' mode on the router by typing enable. Next type 'show ip arp' if done correctly you should get an output similar to the picture.

In the example I have provided there were only 9 IP addresses. However in the real world there could be dozens or even hundreds of IP addresses. To help filter the results on a router type 'show ip arp ?' You will see gigabitethernet' as an option this will let you filter results by interface or sub-interfaces. In my exmaple it typed 'sho ip arp gigabitEthernet 0/0.10' and that listed all IP's on my sub-interface.
Step 5: Filtering the results on a Layer 3 Switch
As stated in Step 4, you will likely have more than 9 IP Addresses. This can be made worse in a messy closet with a 48 port switch running the closet and maybe even some layer 2 switches under that. Luckily in addition to being able to filter by interface you can also filter by VLAN. So type in 'show ip arp ?' and you will see 'vlan' as a listed filter. As you can see I typed in 'sho ip arp vlan 20' and it listed only those IP's in vlan 20. In this case it was the vlan interface and a PC.
I hope this guide was helpful for you. If you aren't sure about something or feel like I missed a step, please let me know.

This guide will you take you each step of the way through setting up a VPN on your Mac. The steps and screenshots used in this tutorial are from OS X 10.10 (Yosemite) but are nearly identical to previous versions of OS X, so you should have no trouble following along, even if you’re not using Yosemite.
If you don’t have a VPN service yet, I strongly recommend and endorse the VPN service provided by Private Internet Access, which works perfectly with OS X on any Mac.
