Between two buildings i want to establish a redundant network connection. If one of the connections fails, the other connection shall transport the network data automatically. There is a SRW2024 in every building. They are connected by a fibre-cable between the miniGBIC ports 24 of every switch. This combination exists two times.
In one building (Keller in the appended pdf-file) there is a rack with MPEG4 codecs. This rack has a built in unmanaged switch with two ports. This ports are patched to one port of the SRW2024.
In the other building (Pforte) there is a PC which receives the MPEG4 streams. It is connected to a fifth SRW2024 which receives the streams of the two connections on ports 1 and 2.
In my first try i have enabled the spanning tree protocoll in all 5 switches. The PC received the MPPEG4 streams. But when i disconnect one of the fibre connections the system comes to an unstable condition where the MPEG4 streams are interrupted sometimes and no network connection is possible.
Even if i reconnect the fibre, the system switches the streams off and on and was not stable.
Where is my fault, is it enough to configure only the fifth switch for spanning tree ?
It would be glad if anyone has an idea to solve the problem.
I have no experience with the series, but I see in the documentation that you can stack the switches. If you stack they, I think they will work as one logical one like a 3750 e.g. and you can use a Port-channel configuration.
If I`m wrong, we should take a close look to the STP config, to make sure which one will be the root and which ports are up to make the situations "controlled"
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
