Post #1 of 10 (5577 views) Permalink %LINK-4-ERROR and %CDP-4-DUPLEX_MISMATCH 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 https://supportforums.cisco.com/document/14716/link-4-errorchar-experiencing-errors-error-message-catalyst-switch-running-cisco-ios 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!

Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Anyone has idea how to fix http://puck.nether.net/pipermail/cisco-nsp/2005-May/020085.html this problem? I have a Cisco 3512XL running Etherchannel with http://www.networking-forum.com/viewtopic.php?t=2927 a Cisco 6509. The Etherchannel has two fastEthernet links. There are "%LINK-4-ERROR: FastEthernet0/1 is experiencing errors" log messages in 3512 side periodically: May 5 14:39:52 pdt: %LINK-4-ERROR: FastEthernet0/1 is experiencing errors May 5 21:55:03 pdt: %LINK-4-ERROR: FastEthernet0/1 is experiencing errors May 5 22:40:37 pdt: %LINK-4-ERROR: FastEthernet0/1 is experiencing errors May 6 08:31:57 pdt: %LINK-4-ERROR: FastEthernet0/1 is experiencing errors May 6 09:17:03 pdt: %LINK-4-ERROR: FastEthernet0/1 is experiencing errors And the interface on 3512 side reports CRC and overrun errors: 5 minute input rate 30426000 bits/sec, 5663 packets/sec 5 minute output rate 33608000 bits/sec, 7128 packets/sec 309548015 packets input, 2524293435 bytes Received 35078 broadcasts, 0 runts, 0 giants, 0 throttles 1479 input errors, 1479 CRC, 0 frame, 1649 overrun, 1649 ignored There is no err reported on 6509 side. And I also check the speed/duplex on both side, they are hardcoded as 100M/Full Duplex. I suspect the port fa0/1 is defect in 3512 side.
