The problem occurs then goes away after 20 or so minutes unless we can narrow down which closet it is coming from and reboot the switch. All of our management tools die during the outage. Does anyone have any ideas on how we might prevent this from happening or track down the offender? We have 6509's in our Core and a mix of 3548's and 3550-SMI. Any thoughts are appreciated. Thanks!
