pelco cctv multicasting problem

Piotr_Jakubczyk — Tue, 26 Apr 2016 22:37:00 GMT

Hello i have trouble with seting up multicasting in my X440-X460 switches. I can ping every device in network, but Video is not showing under my WorkStation or isnt recorded. I have run wireshark on my Workstation sniffing for multicast trafic but no trafic was found. How to diagnose this situation. (Windows firewal is diabled)

Run Wireshark on the workstation affected.
Click Capture > Interfaces > Place a check mark next the Endura NIC > Click Start > Let the capture run for a minute > Click Stop.
In the display filter type udp.dstport==2901 then click Apply.
If the workstation is receiving multicast traffic from the System Manager your output will look like the sample below. If it does not contact your network administrator.

Hints from Pelco:

Does the selected switch support an appropriate number of Internet Group Management Protocol (IGMP) entries for the installation? It is important not to exceed the number of IGMP entries the switch can handle, because it will either block multicast traffic or flood multicast traffic when these limits are exceeded.

Hi Piotr,

Just to confirm, your PC isn't receiving the 239.255.255.250 stream?

What is sending this stream out? Is it in the same VLAN as your PC?

This immage with ip 239.255.255.250 is sample output from wireshark runing workstation when switch is streaming multicast packets from camera to Workstation. In my case output from wireshark is blank.. so my configuration is wrong. All devices are in one VLAN "v3-CCTV". All switches are runing IGMP Snooping but: - Switch1 doesn't see multicast group from Switch2 and Switch3. - Switch2 doesn't see multicast group from Switch1 an Switch3. - Switch3 doesnt see multicast group from Switch1 and Switch2 How to make my switch1 to see multicast groups from switch2 and switch3? Im reading about something called IGMP Querier, is there something like this in Summit X440 or X460?

Is there an IP address on any of the switches in VLAN 'v3-CCTV'? If so, IGMP query is enabled by default in EXOS and there should be a querier. You can confirm this with the command 'show igmp vlan v3-CCTV'.

Are the links between the switches configured to have the v3-CCTV vlan on them?

Glad to hear you were able to get this worked out Piotr!

Couple of observations and questions. If you have igmp snooping enabled the switch will prune back all the mcast streams till it sees a join from your pc.

Each Camera should also have it's own ip and mcast address. If you do a show igmp snoop detail on the switch you should see all the mcast senders (cameras) and what mcast address they are using. This would also tell you if the camera was actually transmitting out a mcast stream.

Your PC would need to do a join for each of the cameras you wish to record and watch.

Each of those ports that are hooked up to a camera should be receiving xxx bandwidth all the time if the camera is working.

You could also create a mirror port and add one of the camera's ports or the vlan and do your sniff from that port to see what the camera's are sending out.

Good luck

Problem solved! Thanks! Any switch hasn't configured IP so i think there wasn't anyone to send query. So i run under switch1 this command and everything works like charm!
