Hi good day,
I have a problem with SW WS-C4503-E, send these messages in the logs;
% C4K_EBM-4-HOSTFLAPPING: Host 55: 32: D1: 00: K8: X8 in vlan 100 is moving from port Gi1 / 1 to port Po1
It is a constant message, I verify it in the documentation and in other blogs, the problem can be STP.
The service is not a problem for the host and the end point, the interface does not present drops, CRC and the reset interface.
What happen in this case?
I look forwarding your comments.
Best regards.

Hi,
Is this a copper or fiber port?
Does the port connect to an end device or another switch/router?
Can you post the configs for the physical port as well as the Portchannel?

Hi Reza Sharifi,
Is this a copper or fiber port?
Copper.
Does the port connect to an end device or another switch/router?
Another SW, specifically HP.

switchport trunk allowed vlan 100,101

Ok, thanks!
Does the physical port go up and down at all?
Also, what is the output of "sh etherchannel summary"

adding to other post, is this port connected to any Esxi or WLC ?
