It looks to me that you have a loop in your network and instability of the spanning-tree-protocol.
You should investigate where the loop is, what is causing it and remediate that issue. These messages are probably symptoms of problems outside of your switch in the network, not on the switch itself.
Spanning tree topologies are expected to be stable and only change if there is a failure in one of your devices in the STP domain, or if devices are added/removed.

Subject: Log getting spammed on an Aruba CX6200
Hey fellow Airheads!
Hoping someone might be able to provide a quick fix for a little annoyance we are running into. We just had to check our switch log to do some troubleshooting and were hit with a wall of text! the following is spamming the log once or twice a second!
hpe-mstpd[3532]: Event|2011|LOG_INFO|CDTR|1|Topology Change received on port lag1 for CIST from source:
the log message has a bunch of different mac addresses, one for each line. I'm guessing there's something we need to turn off on our LAG to stop these messages?
current lag config is as follows (pretty basic config)
interface lag 1
no shutdown
no routing
vlan trunk native 1
vlan trunk allowed all
lacp mode active
lacp rate fast
exit
Thanks in advance for any advice!
