The model installed is SF302-8PP 8-Ports. I agree with you that a model like 2900 should be used. But what about the case I do support for. Is it valid? The question is, what parameter in the data sheet tells that? I have other questions as in the post.

I have an installation for CCTV over Small Business Switches. Some switches have up to five switches connected to it. Some switches is full with CCTV cameras that needs POE. After getting problems in the network, I configured Syslog to monitor the case. Some switches do cold start. Sometimes we have to shut/no shut the port to work again. The camera sends two streams for real time ad recording. The camera sends broadcast, multicast and uni-cast. My questions are, Are small business switches suitable for this installation. What is the parameter in data sheet that tells that (throughput, maximum POE...)? I plan to reduce the VLAN IP subnet size to /26. Is it better to terminate the VLAN at the main switch of the building and route it to the core. Or terminate the VLAN on]n the core. In another words, Is it better to do switching or routing? I believe switching is faster since it is mostly on hard ware in contrast to routing which is done by software.

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.

Thank you Chris Now you could get the five stars . I did several telephone calls and several E-Mails with Cisco partners but I found my information is more than what they have. It seams that the new license procedure is not clear enough for many people. Thank you again

Thank you Chris. I understand that I could enable CME on any two routers of the seven routers I got. Is it correct? What if I enable CME on all of them? The RTU paper licenses I got are identical. What you mean by "SRST and CME licenses are interchangeable"?

As I know, on ISR G2 routers, CME license does not require a license file. I have to accept the EULA to convert the licenses from Eval to Right to use. There is something making confusion for me. For ISR G2 router with IOS Version 15.2(2)T1; does it by default has CME-SRST license or we should order CME license either for feature or seats? If we should order it; then for our case, we ordered seven routers and just ordered two CME-SRST licenses; on which two routers do CME feature runs? How could I know that?

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";

In LMS stacked switches appears not like it is installed in the rack which makes confilict. The up on of the three stacked switches appears in the middel. How to control the units display to reflect the phisical installation? If I reconfigure the switches priority and delet them from LMS then discover it again, does it solve?

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.
