receive flow state logs on nexus 5K

[suthomas1]

Hi,

We have a nexus 5548 (  ver 5.2(1)N1(1b) ).

acting as core. there are servers connected to this in different vlans.

Often , we see following messages in nexus switch. The connections sometimes drop & regain after sometime.

eth101/1/11 operational Receive Flow Control state changed to off

Even if we connected a normal laptop to the switch ports in any of the vlans, we see drops & at that point of time, the ping to gateway(vlan interface on N5K) keeps dropping. Although at times, the connections to the server are still fine even if the ping to gateway drops.

There are not much errors on the interface.

Appreciate help on this. Thanks in advance.

Thanks. I did get few things out of the above, but in a larger way it doesn't really point out possible causes for the error that i encountered.

Appreciate any further suggestions.
