In my own simpleton mindset I see it as follows- I am sure if I am incorrect others will show me the error of my ways!
If you want to mark traffic before encapsulation occurs thus allowing your traffic to be differentiated from other qos traffic then you can or don’t have to use this feature in the following scenarios:
1) If your marking is ONLY based on ip prec/dscp values then qos pre-classify is NOT required 2) If your service-policy applied directly onto tunnel then qos pre-classify is NOT required ( even using additional marked values) 3) If your service-policy applied to physical interface of tunnel(s) using additional marks values such as sip/dip - port- protocol etc then qos pre-classify IS required on each preferable tunnel(s)

Hello cknox1, I've not heard of any Cisco Standard for racking equipment, but there are some familiar terms that provide clues if you're building out more than a few racks. * ToR Switch = Top of Rack -- Use this switch for connections to all devices within the same rack and possibly the racks to either side. * EoR Switch = End of Row -- Use this switch to terminate uplink connections from all the ToR switches in the aisle. This can be a distribution layer switch or may be a core layer switch dependent upon how much capacity you need and the size of your installation. There's another train of thought about locating the EoR Switch in the middle of the row/line-up to minimize long cable runs, but if the connections are optical, there's little difference. In general, you need to ensure you have adequate room between equipment for proper air flow and cooling. You generally want to position heavier equipment near the bottom of the rack to avoid a top heavy rack that can tip over. You may want to consider using patch panels to tie equipment in different racks together, but in today's Ethernet-rich environment, switches take the place of patch panels. Finally, here's a link to some information as food for thought: http://www.anchor.com.au/hosting/planning/Server_Rack_Equipment_Layout_and_Cable_Organisation

I realize this is an old post, but it was referenced in the answer to a recent question regarding the configuration of a back-to-back T1 connection.
My interest here was in providing a bit of extra information that was asked for by huangedmc in his follow-on question, specifically: ** Also, why are the T1's generally believed to have 1.544M of bandwidth, when it's actually 1.536M? (24 * 64K) **
This is a great question and deserves an answer that is found within this wikipedia article on Digital Signal 1 -- "A total of 1.536 Mbit/s of bandwidth is achieved by sampling each of the twenty-four 8-bit DS0s 8000 times per second. This sampling is referred to as 8-kHz sampling (See Pulse-code modulation ). An additional 8 kbit/s of overhead is obtained from the placement of one framing bit, for a total of 1.544 Mbit/s"
In other words, the additional 8 kbps needed to get from 1536 kbps to 1544 kbps is framing overhead unrelated to the data that is being carried. It allows the two ends of the T1 to determine where a T1 frame (physical layer) starts and stops.
