Hi,
We are having problems in the performance of the ethernet. We are using
Cisco 2924 Switch for our Lan but I have observed that of and on various
links goes down and up quiet often. look as follows
Mar 4 16:54:31 dialup20 4448: 1w2d: %LINK-3-UPDOWN: Interface
FastEthernet0/21,
changed state to up
Mar 4 16:54:31 dialup20 4449: 1w2d: %LINEPROTO-5-UPDOWN: Line protocol
on Inter
face FastEthernet0/21, changed state to up
Mar 4 16:54:39 dialup20 4450: 1w2d: %LINK-3-UPDOWN: Interface
FastEthernet0/21,
changed state to down
Mar 4 16:54:39 dialup20 4451: 1w2d: %LINEPROTO-5-UPDOWN: Line protocol
on Inter
face FastEthernet0/21, changed state to down
Mar 4 16:55:11 dialup20 4452: 1w2d: %LINK-3-UPDOWN: Interface

changed state to up
Mar 4 17:37:08 dialup20 4456: 1w2d: %LINEPROTO-5-UPDOWN: Line protocol
on Inter
face FastEthernet0/21, changed state to up
Mar 4 18:25:23 dialup20 4457: 1w2d: %LINK-3-UPDOWN: Interface
FastEthernet0/23,
changed state to up
Mar 4 18:25:23 dialup20 4458: 1w2d: %LINEPROTO-5-UPDOWN: Line protocol
on Inter
face FastEthernet0/23, changed state to up.
I have checked the cables they are perfectly alright. I added
carrier-delay of 4 sec but got no advantage.
What could be the source of the problem and can I solve it.
Thanks
