Hi everybody.
Our AIX-Team installed a new Server, which has problems getting the Management-Interface up. We tried switching cables and switching ports, no success. Not good, but nothing special.
But what I really don't get is interface resets counter in the show interface-output:
======================
n99903-ms02#clear counter
Clear "show interface" counters on all interfaces [confirm]y
[power on server]
n99903-ms02#sh int fa0/23
FastEthernet0/23 is down, line protocol is down (notconnect)
Hardware is Fast Ethernet, address is 0019.065b.a019 (bia 0019.065b.a019)

interface FastEthernet0/23
description s002fa
switchport access vlan 12
no logging event link-status

no snmp trap link-status

end
======================
The counter stays the same for several hours - just the interface reset in the first second. The Event does not produce any log-entry.
Is there any clear interpretation of a link, which is notconnect, but, has no packets in or out, but starts with an Interface reset? Can we blame the Server-NIC for sure, or is there perhaps a misconfiguration somewhere? We have the same behavior on all 4 interfaces of the Server, so before I accuse the Hardware I prefer to be sure, that it is not a fault on the network-side...
thx in adanvace for any hints
