Problems WS-C4503-E %C4K_EBM-4-HOSTFLAPPING:

Jhon1989

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.

 

 

Port Channel1:

 

interface Port-channel1
switchport
switchport trunk allowed vlan 100,101
switchport mode trunk
switchport nonegotiate
logging event link-status

 

 

Best Regards.

 

 

 

 

 

 

Ok, thanks!

Does the physical port go up and down at all?

Also, what is the output of "sh etherchannel summary"
