I configured ip sla video probes on 2951 to send probes to 3945, but it seems that i meet some problems, can anyone help me?

Can anyone help me with this?
Be sure your ISR's have enough PVDM-DSP's allocated for IPSLA-VO use.
The CTS-1080P-Best video profile runs at 4MB/s and needs at least 1 - PVDM3-16 DSP card
to run up to 4 - CTS-1080P-Best sessions (60-credits per session).
Thanks for Michael's answer! It helps a lot!
BTW, i have some other questions, which need your help!
#1.how can i find more info about PVDM-DSP used for ISRG2 devices, or how can I find these limitations to catalyst 3k,4k or ISRG2?
#2.after i search in the CCO&medianet website, I find we need to support ASR1k and some other device described in medianet roadmap ppt. But I check the medianet data sheet and find 3k,4k and ISRG2 devices support this feature. Do you know which types of devices support this feature as a sender now?
Becasue we need add some device support in our NMS product.
Anyway, thanks very much for your help!
Answers to your questions;
#1) Use this Doc as a guide for DSP allocation:
Also look at this Doc for deploying IPSLA-VO across platforms:
#2) Medianet Datasheet shows the ASR-1K supporting Media-Monitoring on IOS-XE 3.5 and higher. Performance monitoring & Mediatrace, however IPSLA-VO is not currently supported. I would need to check with engineering if there are any plan to support IPSLA-VO on the ASR-1K. It does not seem to be in the roadmap I have, but these roadmaps change all the time. The 3945E ISR-G2 can Send up to 175 CTS-1080P-Best video sessions with a 20% CPU mainly because the DSP offload the CPU. However the Responder can only receive 80 of these video sessions with a 72% CPU utilization. Your Application could use Multiple ISR's to achieve higher density. Our Cisco Prime Collaboration (CPC) NMS provides a GUI interface to control the ISR's & Switches to setup tests within your network. CPC does a lot more with Medianet including; MSI, Mediatrace, Perf-Mon, Metadata. A very powerful video collaboration Mgt system.
