I assume the hostflapping is causing a spike in CPU since the packets are not being processed by CEF. A checkpoint firewall is on the other side of the two ports. Has anyone run across this problem in general or with Checkpoint firewall using the same mac on two different ports? How could I solve this?
The issue can occur due to Spanning Tree Protocol (STP) loops in the network that cause packet drops from the specific host. In addition to packet drops, STP loops lead to several other symptoms, which are listed here:
Loss of connectivity to, from, and through affected network regions.
High link utilization (often 100 percent).
High switch backplane utilization (compared to the baseline utilization).
Syslog messages that indicate packet looping in the network (for example, HSRP duplicate IP address messages).
Syslog messages that indicate constant address relearning or MAC address flapping messages.
An increase in the number of output drops on many interfaces.
