Hi NetPro,
currently my port-channel config at Cat6509 as below.
Interface Port-Channel9
switchport
switchport access vlan 64
and used at Cat4507
interface GigabitEthernet4/29
description Cisco
switchport access vlan 64
spanning-tree portfast
channel-group 9 mode on
interface GigabitEthernet4/39
description Cisco
switchport access vlan 64
spanning-tree portfast
channel-group 9 mode on
so, when i " show interface gi 4/29 "
i got input and CRC error.
Output queue: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 7434000 bits/sec, 669 packets/sec
1987713842 packets input, 188931850324 bytes, 0 no buffer
Received 216462 broadcasts (10659 multicast)
3743826 runts, 0 giants, 0 throttles
6074501 input errors, 2330675 CRC, 0 frame, 0 overrun, 0 ignored
0 input packets with dribble condition detected
12836531883 packets output, 18532759512753 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 output buffer failures, 0 output buffers swapped out
any suggest ?

Hi Jackal,
could it be that one or more of the interfaces on one of the switches are in half-duplex modus?

Hi Marcos,
initially, i've hardcoded to both site but end up i still got the CRC error, and then when i try auto i still got the same thing.
i am curious about what went wrong ?

Hi Jackal,
did you try other cables on the ports? Did you try other Ports? Could it be that the cables be out of specifications? Could it be that the distance between the switches is too long? Did you got the same errors when you unchannel the ports and try one port each other to find out if one or more ports are defective? Personaly I would try it without portfast on the channel, because there is a switch on the other end and the spanningtree could not run correcly during port initialisation.
I hope this will help you to find a solution for your problem.
Regards
Marcos

Hi Marcos,
yes, i did change cables and another switch port as well, but CRC error still remain. so you would suggest remove the spann-portfast on channel-group ? ok , i will try it and let you know then.

Hi NetPro,
i have tried to remove the portfast from the channel-group, but i still got the CRC error ? something i dont understand was from the etherchannel - Gi4/29 and Gi4/39.
since this is port-channel how come the CRC error only occurred on Gi4/29 only ?
even thought i have changed the switch port as well, i still got the CRC error !

Hi,
which type of Giga module do you have installed?

Do a show interface status and see how it negotiated the link and at what speed . One side or the is probably not correct . Match both sides either hardcode both sides or leave both sides as auto .

Hi Glen,
yes, i have hard code for both sites.
Hi Andrea,
i am using WS-X4448-GB-RJ45 module.
