We are having an issue with DAI blocking traffic if we move a device between switches in a stack, but no issue if you move between ports on the same switch. For example if I move from 1/0/5 to 1/0/24 there is no issue, but if I move from 1/0/5 to 3/0/5 the traffic gets blocked. The DHCP snooping database updates and shows the correct MAC/IP bindings following the device to the port. Has anyone seen this issue?
We are seeing this on stacks of S3500s running 220.127.116.11.
