VCN3000 high-speed download abend

Publication Date:  2015-01-29 Views:  20 Downloads:  0
Issue Description
When try to download the recording in high-speed, in the first few seconds, the speed is normal, but it will reduce to 0 soon.
Handling Process
1. Capture the data between server and CU when doing the high-speed download, find out that the download isn’t abort just the speed reduce to 0.

2. The interface configuration is according to the requirement, the interface is support auto-negotiation and the speed is 1000Mb/s.
3. So the problem is probably caused by the network, so we checked the configuration of switch and firewall.
4. The firewall arrested RSTP, the system use RTSP for transfer file, then we do “no inspect rtsp” on firewall.
     Policy-map Global policy 
     Class inspection_default   
     Inspect rtsp
Root Cause
The firewall policy inspects RSTP.
Solution
Change the policy of firewall.
Suggestions
When the CU client and server are in different network, please make sure the network permits the transfer.
