Re: Need Help Urgent!!

For the ├в Excessive broadcasts", it a Critical event and it├в s (formerly broadcast storm).
For the ├в High collision or drop rate", it a Major event and it├в s (formerly over bandwidth), therefore you have to check the two side speed and duplex mode.
For the ├в Excessive crc/alignment error├в , it a Minor event and it├в s (formerly problem cable)

Re: Need Help Urgent!!

thank you for your help.
all of my switches are configer to work in auto . do i need to change this configuration?
"100/1000 auto"

Re: Need Help Urgent!!

First question has anything changed on the network?
Possibly you are looking at something broadcasting more on the network causing problems. (More broadcasting means more collisions).
Are you running spanning tree? Are you switches networked together in a loop for failover?
(If they are in a loop and spanning tree has failed/stop running on a switch this will cause this error)
