have you tried swapping out the fiber? Maybe switching tx/rx ?

|Hi Christian!
|
|I don't tried it, but on the C2924 I cannot change the media
|type, only on the C2960 side...
|I think the media type on the C2960 is set to auto, and it
|recognizes as SFP. I think this is ok...
|
|C2960: Half-duplex, 100Mb/s, link type is auto, media type is
|100BaseFX SFP

|Try setting the media type under the interface on the 2924?

||
||Hi all Experts!
||
||
||
||I have the following problem:
||
||We have two switch connected by fiber cable:
||
||
||
||WS-C2960G-24TC-L:Gi0/21<<<<< >>>>> Fa1/4:WS-C2924M-XL
||
|| FIBER
||
||
||
||The problem is, that the C2924 Switch sends the following messages in
||every minute:
||
||
||
||Apr 3 08:11:33.112 MET-DST: %LINK-4-ERROR: FastEthernet1/4 is
||experiencing errors
||
||
||
||On the C2960 I cannot change the duplex or the speed settings.
||
||On the C2924 I've changed the duplex settings, but:
||
||- If it's set to duplex auto or duplex full, then
||%CDP-4-DUPLEX_MISMATCH error on the C2960 Switch
||
||- If it's set to duplex half, then %LINK-4-ERROR on
||the C2924 Switch
||
||
||
||Why the newer Cisco Devices and IOS doesn't support the speed and
||duplex settings?
||
||Does these errors highly affect the network performance?
||
||Is there any solution for this problem?
||
||
||
||
||
||Thank you in anticipation!
