Qos Priority

We just talked about tagging traffic and policing traffic, but we haven’t talked about prioritizing traffic. Tagging just sets a value in the header. Policing sets a “bandwidth ceiling” that can’t be crossed. Prioritization guarantees a certain amount of bandwidth for a flow/app/etc. no matter what’

QoS Policing

We covered QoS tagging the other day, but that just marks packets. I think you’re old enough now that we should actually do some policing. Policing is where you restrict the amount of bandwidth that a flow or set of flows can use. For example, say you have a

Default Route via DHCP on an ASA 5505

I finally got my ASA 5505 up and running at the house, but I ran into a little problem — the box wouldn’t add the DHCP-provided default route into its routing table. That one threw me for a loop since the box is made for SOHOs, but it makes sense
