Hi, all!

I have a problem with total output drops on the etherchannel.

I have the etherchannel between 
cisco WS-C3560E-24TD (System image file is
"flash:/c3560e-universalk9-mz.122-46.SE.bin") and
CISCO7606 (SUP-32) (c7600s3223_rp Software
(c7600s3223_rp-ADVIPSERVICESK9-M), Version 12.2(33)SRB4, RELEASE
SOFTWARE (fc3))

On 3560-E:
interface Port-channel1
 description CORE
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,2,3,4
 switchport mode trunk
 switchport nonegotiate
 load-interval 30
 storm-control broadcast level pps 500k
 storm-control multicast level bps 1m
 spanning-tree portfast trunk
 spanning-tree bpdufilter enable

One of the link:
interface GigabitEthernet0/7
 description CORE-1
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,2,3,4
 switchport mode trunk
 switchport nonegotiate
 load-interval 30
 speed 1000
 duplex full
 storm-control broadcast level pps 500k
 storm-control multicast level bps 1m
 no cdp enable
 channel-protocol lacp
 channel-group 1 mode active
 spanning-tree portfast trunk
 spanning-tree bpdufilter enable

On both devices:
port-channel load-balance src-dst-ip

QoS disabled

output of the show interfaces command:
sh int po1
Port-channel1 is up, line protocol is up (connected) 
  Hardware is EtherChannel, address is 001e.bed9.d308 (bia
001e.bed9.d308)

  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Full-duplex, 1000Mb/s, link type is auto, media type is unknown

  Members in this channel: Gi0/7 Gi0/8 Gi0/9 Gi0/10 Gi0/11 Gi0/12 Gi0/13
Gi0/14 
  ARP type: ARPA, ARP Timeout 04:00:00
  Last input never, output 00:02:19, output hang never
  Last clearing of "show interface" counters never
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This counter constantly increasing :(

Can anyone help me here?
