Hello all,
since few months ago we are having problems with some network interfaces where we have Solaris servers connected on our Catalyst 6500 with the following configuration:
interface GigabitEthernet1/4/36
description 1/17/11_PALMERA1-ACCESOUNIX
switchport
switchport access vlan 101
switchport mode access
spanning-tree portfast edge
spanning-tree bpdufilter enable
spanning-tree bpduguard enable
The interfaces of the Solaris servers are part of a cluster using Veritas software and the traffic on the switch interfaces are outbound how int can see on the beginning output:
GigabitEthernet1/4/36 is up, line protocol is up (connected)
Hardware is C6k 1000Mb 802.3, address is e05f.b97a.ebbb (bia e05f.b97a.ebbb)
Description: 1/17/11_PALMERA1-ACCESOUNIX
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 1000Mb/s, media type is 10/100/1000BaseT
input flow-control is off, output flow-control is off
Clock mode is auto
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output 00:00:16, output hang never
Last clearing of "show interface" counters 12w0d
Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 1000 bits/sec, 1 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts (0 multicasts)
0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 watchdog, 0 multicast, 0 pause input
0 input packets with dribble condition detected
17385683 packets output, 1417944779 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier, 0 PAUSE output
0 output buffer failures, 0 output buffers swapped out
We have opened a query to Oracle support and they have said that this is the normal operation but on the switches, the interfaces are flapping
continuously:

Has anyone the same problem or that knows what is it happening?
Although this behavior does not impact on the production services, fills the local log of the switch; and if we need to find some event, it is imposible mission!
Regards and thanks a lot.
