DHCP packets are dropped due to high packet rate

Hi all.

The last few days the following message has started appearing in the logs of our two E3800 distribution switches:

W 04/11/16 08:22:33 02698 dhcp-snoop: backplane: DHCP packets are dropped at port 25 due to high packet rate.

Port 25 is a 10G connection to our core switch. Has anyone come across this before? The switches are running software KA.16.01.0004

Re: DHCP packets are dropped due to high packet rate

Hello.  There is a 100 pkts/sec rate-limit on DHCP packets with DHCP-snooping enabled, it's a DoS protection mechanism.  It's been in place for some time however the log message is new for X.16.01.
