QOS has the following sequance of operations: Classify-Mark-Bandwidth and priority. Classify is a load on the processor and better to be done while the packet input to the network. So, it is applied on input interface. It could be applied on output also to deal with different WAN technology (ATM & MPLS for example). And hence it mark the packet Bandwidth and Priority by logic is to be done on the output interface. The router may has more than one interface with different speeds Hence, each class will have different bandwidth on each interface. ... View more

Thank you. We solved it for one stack by deleting the configuration, then follw up next steps (which I got from another discussion (How to stack 2 3750 switches?). We will test it with another stack to confirm that it is solved. 1.  Power up the switch master (ONLY!); 2.   Attach the stacking cable to the rest of the members; 3.  Power up the members ONE-AT-A-TIME and based on the order of your choice. Example, if switch 2 is the 2nd switch, then power this switch after the master has been powered up and stacking cable has been applied.  This is followed by switch 3, switch 4, etc. Rules-of-the-Thumb: 1.  Ensure all switches are running the same IOS version, same Feature Set (example IP Base); 2.  Once all switches are up, ensure you enable "switch n priority XX"; ...

I did some study to understand the relation between the IOS, CME and Phone files. I will add my what I got soon because there is one point not clear for me. ... View more

I don't know the version that was on the IP Phone before it fail. I got the files on CME from both cmterm-7911_7906-sccp.8-5-4.zip and cmterm-7911_7906-sip.8-5-4.zip. The reset to default I found (# during reboot then 123456789*0#) does not work for 7911. ... View more
