thanks for your reply
here is the information:
1. what is the current aging time set for port-security?
it is default setting
2. For the mac-addresses in conflict that's shutting down the port, what device is it? Laptop?
yes,,ladtop,,some of them running VM
3. Do you have "sticky" option enabled? From what you described, I think not, but I just to make sure. Don't enable "sticky" option unless you've a real business needs for it.
no,we don't enable that feature
4. Is it the same mac-add that has been causing the problem or different mac-addresses every time?
no, it is random mac-address.
5. Sounded like the problem arose after you implemented port-security, is it correct?
no, we have run this stack for 3 weeks, and this issue just came last weekend.
6. Can you post the switchport config?
just for example,portf1/0/24
int f1/0/24
sw mo acc

sw port violation restrict
spanning portfast
spanning bpduguard enable
