Using VMware and CDP information (HP and Cisco Switches)

So on of the most valuable networking features of VMware is setting up CDP information or LLDP (if using non cisco devices). We can see exactly which VMNIC is plugged into which port.

ESXi can receive and display CDP information within the client or web client, but this doesn’t work with HP switches which use LLDP, which you will see in the below examples for both vendors.

Below the environment is plugged into a HP switch and no CDP information is being displayed into the standard switch, however we can send CDP information from VMware ESXi to the HP switch. (But from a Cisco Switch the information does show)

Creating VPN tunnel between Cisco ASA and Watchguard XTM

Today was the second time I’ve done this in around a year, it’s a little uncommon to be honest, which means googling advice on how to do it, is a bit thin.

Todays walk through is also made even more different by the fact that at the branch site containing the Watchguard, its connected to a Cisco 857w router, with a Public IP address NAT’d to it due to the site having an ASDL connection.

See the below diagram I’ve sketched up in visio;

It’s actually easy enough to setup, the official documentation on the Watchguard is here, but doesnt cover it all.
