When using 3 x670_48x switches in a stack (native) at a client, I'm experiencing high stack-port utilization. This reaches 100 percent on certain stack ports. I am using native v160 stacking.
The firmware used on these switches is 22.214.171.124, the license is CORE.
The setup is used to stream multicast raw video within a VLAN to media devices (monitors and servers). The bandwidth of the stream is about 3,6 gb/s (uncompressed).
When contacting our supplier we were told that all multicast traffic will flow through the stack ports. This will cause packet drops on the stack ports and will saturate the stack ports.
I was under the impression that even with stacking, the multicast should stay within its own VLAN?
To resolve this issue, is it necessary to remove native stacking from our setup? If not, is there an alternative solution to our problem?
If there is any more information required to answer my question(s), feel free to post below.
Thanks in advance,
