First of all, the post isn’t about explaining QoS. Configuring AutoQos on Cisco switches should be very easy. At least, that is what all the Cisco documentation tells you.

The session about firewall design and deployment didn’t reveal a lot of new things about the Cisco ASA appliance or FWSM module. The only new thing for me was the possibility to configure a redundant interface for a Cisco ASA appliance. The screen shot below shows the cabling scheme for an implementation with and without … Read More
