I’m still working on the ONT test and doing labs, so I marked up a lab for me to work. I’m using the same setup as I did last time. The two routers are 3640s running 12.4(25b). Part of the lab was to identify HTTP…
I’m still studying for the ONT test, so I did some labs tonight. One of them was to demonstrate the qos pre-classify command for tunnel interfaces. When you have a packet sent over a GRE tunnel, the ToS field gets copied to the GRE packet,…
Imagine that…another ONT notes post. This one is about QoS on wireless networks.
Here are some more notes from my ONT studies. AutoQoS seems to be pretty straightforward.
Here are some more ONT notes. We study pre-classifying and end-to-end QoS this time.
Here’s another set of notes from my ONT studies.
Here are some more notes from my studies. Of course, no one cares about them but me, but it’s my blog. I’m sure someone will find it useful. Please help to correct dumbass mistakes. Congestion Speed mismatch – traffic leaves a lower-bandwidth interface than the…
